Description
Pilot Operated Relief Valve
Model: 14E-TPW
Description
The Groth Models 14E and 14F Pilot-Operated Relief Valves are used to replace weight-loaded or spring-loaded valves in many applications to increase efficiency and reduce evaporation losses. Several advantages are obtained over the traditional valves. For example, the process pressures may be closer to the set pressure than would be considered prudent and safe with the traditional valve. Additionally, greater conservation is obtained due to minimum product loss which in turn provides increased profits.
Features
Ease of precision settings
Only the pilot needs to be set
Lower profile and weight than spring operated models for high settings
Remote pilot sensing option allows the pilot to sense the true system pressure
Remote or manual blowdown available
Main valve remains tight to set pressure
Flow capacity available at 10% overpressure
Modulating action conserves product (available on most settings, consult factory)
Top entry allows valve to be serviced without removal from mounting
