Trane VAL10766C Safety Relief Valve – DN20 (3/4"), Spring-Loaded Pressure Relief Valve For RTWD / RTWS Screw Chillers – Genuine HVAC Parts, Compressor Parts, Central Air Conditioning Refrigeration Parts

The Trane VAL10766C is an original factory spring-type safety valve (Safety / Relief Valve), serving as the final safety barrier in the pressure system of the chiller unit. When the pressure inside the condenser, evaporator, or pressure vessel exceeds the set value, the medium thrust overcomes the spring preload force, causing the valve disc to automatically open and release the medium to the outside of the system to relieve pressure; once the pressure drops to the return seat pressure, the spring re-engages to compress the valve disc and automatically close to restore sealing, effectively preventing equipment from deforming due to overpressure, rupturing pipes, or causing personnel injuries. This valve is manufactured with high-quality materials and precise structure, featuring accurate action pressure, sensitive response, tight reseating, reliable sealing, and excellent pressure resistance and corrosion resistance. It can operate stably for a long time. It is suitable for the overpressure protection of the condenser and evaporator in Trane RTWD, RTWS, etc. water-cooled screw chiller units. It is a necessary component for the regular calibration and replacement of the safety valves of the units.
