RPD Pneumatic Actuator
Double acting pneumatic actuator for 90° operation
for On-Off and Modulating heavy duty service
General
The RPD pneumatic actuator series was
engineered and is manufactured to
provide maximum torque output with
minimum supply pressure.
Simplicity, reliability and economy are at the
top of the list of design parameters.
The RPD actuator is suitable for any quarter
turn application such as ball, plug, butterfly
valves or dampers, in both On-Off and
Modulating heavy duty service.
Features
• Totally enclosed, weatherproof housing in
nodular cast iron for maximum strength and
suitable for use in hostile environments
• A compact rack and pinion design provides
simple construction and constant output
torque throughout the 90° stroke
• An adjustable bronze sliding block supports
the transverse force exerted on the rack by
its engagement with the pinion
• Rack and pinion in nodular cast iron, output
shaft in alloy steel for maximum strength
• The rack is nitrided for minimal friction
• External travel stops for precise angular
stroke adjustment between 80° and 100°
• Electroless nickel plated and polished
cylinder and output shaft for corrosion
resistance and minimal friction
• Floating type piston seals for low hysteresis
and high sensitivity, preventing sticking
problems
• Lever or jackscrew manual override

sizing criteria
Valve data required
Break to open torque
Required torque to move the valve away from its closed position under the full differential
pressure. This torque value must take into account the possible sticking effect which could affect
the valve if it is closed for a long time.
Reseating torque
Required torque to close the valve under the full differential pressure.
Break to close torque
Required torque to move the valve away from its open position with maximum working pressure in
the pipeline.
This torque value can be high in the case of “double block and bleed” ball valves.
End to open torque
Required torque to fully open the valve.
Running torque
Required torque to actuate the valve in opening and in closing without differential pressure along
the angular stroke except the fully open and fully closed positions where the required torques are
those listed above.
Dynamic torque
Required torque to actuate the valve in opening under the medium flow through the valve. This
torque value is high particularly on modulating service and when the medium speed and specific
gravity are high.
The angular position where the dynamic torque occurs has to be defined.
Safety factor
It is essential to confirm if the above torque values include a safety factor. Depending on the valve
application additional safety factors may have to be considered over and above those
recommended.
Maximum allowable stem torque
Maximum torque the valve stem can withstand.

Operating conditions data required

Supply medium pressure range (minimum, normal, maximum)
Type of actuator: double acting or spring return to close or spring return to open
On-Off or Modulating service
Frequency of operation and required operating times
Actuator sizing general criteria
A safety factor must be included during sizing if not included in the figures supplied by the valve
manufacturer.
The safety factor value has to be defined as a function of the valve type and size, of the working
condition and of the operating time. The safety factor is usually included in the range from 1.2 to
1.5: higher values have to be employed in case of extreme working conditions (for instance in
case of low temperature, dirty and/or high viscosity medium, very infrequent operation, modulating
service, short operating time).
The output torques values listed in the performance tables of actuators do not include a safety
factor but are the minimum guaranteed torques.

RPD/RPS Pneumatic Actuator
sizing criteria
RPD actuators, because of the rack and pinion mechanism, have a “constant” output torque with
a fixed supply pressure. For actuator sizing the following comparisons between the valve data,
including the safety factors, and the actuator data have to be performed.
• Check that the actuator output torque, with minimum supply pressure, exceeds all the valve
required torques
• During operation the actuator provides, along its full travel, only a torque equal to the required
valve torque. No problems will occur if the actuator output torque, as listed in the performance
table, exceeds the valve maximum allowable stem torque.
But if there is the possibility that the valve stops along its stroke, due to abnormal conditions, it
is necessary to check that the actuator output torque, with the maximum supply pressure or
with the regulated pressure, if a pressure regulator is fitted on the pneumatic supply, does not
exceed the valve maximum allowable stem torque and the actuator max operating torque

For actuator sizing the following comparisons between the valve data, including the safety factors, and the actuator data have to be performed.
• Check that the “spring ending torque” of the actuator exceeds the valve “reseating torque” with maximum differential pressure
• Check that the “air starting torque” of the actuator, with minimum supply pressure, exceeds the valve “break to open torque” with maximum
differential pressure
• Check that the “spring starting torque” of the actuator exceeds the valve “break to close torque” with maximum working pressure in the pipeline
• Check that the “air ending torque” of the actuator, with minimum supply pressure, exceeds the valve “end to open torque”
• Where a valve “dynamic torque” is present, check that it is overridden by the actuator “air intermediate torque” with minimum supply pressure.
“Air intermediate torque” is calculated by the formula: AIT = (AST + AET)/2. For a more accurate sizing BIFFI should be consulted
• When required, since there is the possibility that the valve stops along its angular stroke because of abnormal conditions, it is necessary to check
that the actuator “spring starting torque” and the “air starting torque”, with maximum supply pressure or with the regulated pressure, do not exceed
the valve maximum allowable stem torque and the actuator maximum operating torque

RPD/RPS Pneumatic Actuator
control system
General
BIFFI has the ability to apply advanced
engineering technology to design and
manufacture of pneumatic controls and
accessories.
The experience and knowledge acquired in
the actuator industry allow BIFFI to meet with
the highest requirements for control modes
and operating conditions by correct selection
of schematics, components, materials and
protection treatment.
The actuator service can be On-Off or
Modulating. Actuator control can be local or
remote by electric or pneumatic signals.
The control system can include devices for
automatic operation or stay put in case of
emergency (electric or pneumatic supply
failure, high temperature, low or high pipeline
pressure etc.).
For heavy duty service or special working
conditions (for example low working
temperature, sour gas supply, special
emergency operation, etc.), control valves
specially designed and manufactured by BIFFI
can be supplied.
Control systems can either be mounted on a
panel or enclosed inside a weatherproof
cabinet.
Control systems can either be supplied
separately or assembled on the actuator.
The actuator housing has dedicated threaded
holes for the mounting of control systems and
accessories.
Main components of the control system
- Stop valves, check valves
- Air conditioners (filter, pressure regulator with pressure gauge, lubricator)
- Air storage tanks with accessories (relief valve, pressure gauge with stop valve, drain plug).
Standard air tanks are designed, manufactured and tested according to ISPESL Standard. If
required the tank can be supplied in accordance with different codes like ASME Vlll DIV. 1,
SNCT/France, BS/UK, TÜV/Germany, etc.
- Solenoid valves, manual valves, pneumatic pilot valves
- Flow regulators
- Quick exhaust valves
- Pressure switches - pneumatic or electric
- Terminal enclosures
- Positioners - pneumatic or
electropneumatic
- I/P converters
Features
• The standard components have the body in aluminium.
Brass and stainless steel versions can be supplied
• The standard directional control valves are spool type. Poppet type valves are available
• The standard solenoid valves are air pilot operated. Direct solenoid operated valves are
available
• Manual override for solenoid valves is available
• Manual reset is available for solenoid valves and for pneumatic pilot valves
• The electrical component enclosures can have explosionproof and/or weatherproof protection.
The explosionproof enclosures are in accordance with CENELEC Standards EN 50014 and EN
50018. Enclosures in accordance with UL or CSA Standards can be supplied. Components
suitable for use in intrinsically safe circuits are available
• Terminals enclosures with increased safety protection are available
• The pneumatic connections are in copper pipe and brass fittings as standard; stainless steel
can be supplied on request
• Standard weatherproof cabinets for control systems are in carbon steel. Glass reinforced
polyester and the stainless steel on request

The diagram shows the simplest On-Off
control. The gas supply pressure is applied to
one side of the cylinder and exhausted from
the opposite side.
When the control valve (2) is actuated the
connections of supply and exhaust to the
cylinder chambers are reversed.
The control valve can have many types of
actuating devices (solenoid, manual control,
pneumatic pilot, spring, etc.).
The spring return control valves allow
"fail safe" operation.

On-Off service: air fail safe system

This system allows "fail safe" operation
when the pressure in the gas supply line
drops below a set value.
The diagram shows the actuator (1 ) in the
"fail safe" condition.
When the gas supply pressure drops below
the pressure switch (5) set point, the
pneumatic supply to the solenoid valve (6)
pilot is exhausted and the actuator moves to
the "failsafe" position by using the gas stored
in the tank (4). The tank is connected to the
gas supply through the check valve (3).

When modulating control is required as a
function of a pneumatic or electric control
signal, a positioner (5) is used, which controls
the supply to the actuator cylinder to keep the
valve in the required angular position.
The positioner has a mechanical linkage to
the actuator, for a feedback of the valve
position.
Control System for Pneumatic Actuators
typical control systems for spring return actuators
On-Off service: three way control valve
The diagram shows the simplest On-Off
control. The control valve (2) has two
positions. In one position the gas supply
pressure is connected to the cylinder
chamber, and the actuator performs the
"pneumatic" operation. In the other position
the cylinder is connected to the exhaust and
the actuator moves under the operation of the
spring.
The control valve can have many types of
actuating devices (solenoid, manual control,
pneumatic pilot, spring, etc.).
Spring return control valves allow
"fail safe" operation.

On-Off service: quick spring operation

When fast action is required under spring
operation, a quick exhaust valve (3) is installed
in the cylinder port to exhaust the gas from
the cylinder directly to the atmosphere.
When the control valve (2) opens to the
atmosphere a differential pressure is created
across the quick exhaust valve (3) causing it
to open.
The resultant high flow capacity from cylinder
to atmosphere allows quick spring operation
of the actuator.
