THERMAL RELIEF VALVE (TRV)/POP ACTION VALVE

THERMAL RELIEF VALVE (TRV)/POP ACTION VALVE

A compact Thermal relief valve designed to prevent
damage to piping and equipment caused by the expansion of
liquefied gases. . The thermal relief valve relieves the overpressure
in a piping system of fluid due to temperature rise.
When liquefied gases are trapped between two closed valves (a
situation known as liquid lock) the reheating and consequent
boiling can lead to a dangerous rise in pressure In most cases
pressure relief valve limit the system pressure to a specific set
level.

The SEPL thermal relief valve has been designed with this
application specifically in mind using materials which are
particularly suited to the purpose. One major benefit of this is that
the valve will not in its seat even when left unused for long
periods of time. The valve also reseats correctly after venting off
the expanding fluid, thus preventing the waste of expensive
cryogenic gases. It is available with a variety of outlet
connections to suit the customers’ requirements.
All valves are tested, locked to prevent unauthorized tampering, prior to dispatch
