Cryogenic Thermal Relief Valve CVF10CF45N00

Parker Bestobell's compact cryogenic thermal relief valve are designed to prevent damage to piping and equipment caused by the expansion of liquefied gases.

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. The Parker Bestobell Thermal Relief Valve has been
designed with this application specifically in mind using materials which are particularly suited to this purpose.
One major benefit of this is that the valve will not stick 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 degreased for oxygen duty, assembled in clean room conditions and pressure tested prior to dispatch.
