DCV 10 Stainless Steel
Disc Check Valve for use with Automatic Pump Traps
Description
The DCV10 disc check valve has been designed specifically for use with
Spirax Sarco's APT14HC and APT14SHC automatic pump-traps. The
check valve ensures the correct flow of condensate and other suitable
fluids through these condensate pumps and also prevents reverse
flow.
Sizes and pipe connections
The PN25 design is available in sizes DN25, DN40, DN50 and DN80
to fit between EN 1092 PN16 and JIS / KS 10K flanges.
Please note: The Class 300 design is available in size DN40 only
to fit between ASME B 16.5 (ANSI) Class 150 and Class 300 flanges.
Standards - Designed in accordance with BS EN 14341:2006. This
product fully complies with the requirements of the European Pressure
Equipment Directive 97/23/EC.
Shut-off - Shut-off conforms to EN 12266-1:2003 Rate F.
Certification - This product is available with certification to EN 10204
3.1. Note: All certification/inspection requirements must be stated at the
time of order placement.

Operation
The DCV10 is opened by the pressure and flow of condensate and
is closed by the pressure of the spring when flow ceases and before
reverse flow occurs.

Pressure loss diagram with open valve at 68°F (20°C).
The values indicated are applicable with to spring loaded valves
with horizontal flow. With vertical flow, insignificant deviations
occur only within the range of partial opening.
The curves given in the chart are valid for water at 68°F (20°C). To
determine the pressure drop for other fluids, the equivalent water
volume flowrate must be calculated and used in the graph.
______
Vw = √ S.G x V E
A
Vw = Equivalent water volume flow in GPM
S.G. = Specific Gravity
V = Volume of fluid GPM
Pressure loss information for steam, compressed air and gases is
available from Spirax Sarco.
