Edward Hermavalve
Condensate
Pump
• High Pressure Coolant Injection
When a packed valve can not meet
atmospheric leakage standards,
Flowserve Edward Valves can provide
the hermetically sealed Hermavalve ®.
Unlike the numerous bellows-type
valves on the market, the Hermavalve ®
provides the tight shutoff, enhanced
flow, and durability characteristics of
our Y-pattern globe valve in a compact
diaphragm-sealed design. Built for
applications of 2500 psig at 650°F,
these valves have a service life of at
least 4000 cycles without any external
leakage.
Please refer to items 9-18 in the key for
recommended valves for these systems.

Edward’s gas-hydraulic actuators for
large, fast-closing main steam isolation
valves are subjected to a rigorous
qualification program to provide
dependability of operation under
the most adverse conditions. Some
features include:
Flowserve desuperheaters cool process
steam by injecting atomized cooling
liquid directly into the flow. Available
separately or with an integrated control
valve to attain maximum rangeability,
responsiveness and control, Flowserve
desuperheaters offer the following
benefits:
• Complete atomization
• Lowest ∆p atomization available
• Multiple small spray nozzles
• Simple design with no moving parts
• Fail safe operation to either close or
open valve within an adjustable range
of 3 to 10 seconds
