HAT/RA-HP Heat Actuated Trap/Reverse Acting – High Pressure


The HAT/RA-HP valve is commonly used as a thermal relief valve on fire pumps and high-pressure water pumps to keep them cool during idling. Rated to1000 PSIG (69 BAR), this self-operating valve monitors fluid temperature and will automatically open to discharge over-temperature fluid. The valve will modulate closed again once cooler fluid backfills to the system to reduce energy and water waste.
