Water relief valve ECONO/HAT-RA

stainless steelbrassthermal

The ECONO/HAT-RA is a pump thermal relief valve designed to protect domestic water supply booster pumps from over-temperature damage, while reducing water waste and increasing overall system efficiency. Operation As the fluid temperature increases to within the operating range of the pump seal temperature control, ECONO/HAT-RA, the thermal actuator modulates the valve open to discharge the over-temperature fluid. If the temperature is above the acceptable range, the thermal relief valve will continue to modulate open allowing additional fluid discharge. As the outlet temperature falls, the thermal safety valve then modulates toward the closed position, reducing flow. This modulating action maintains a relatively constant fluid temperature even as operating conditions vary. This water discharge can be collected, reused, or repurposed to reduce waste. Typical Applications ECONO/HAT-RA pump seal temperature control valve is primarily used for thermal relief on booster pumps to keep them cool during idling. It can also be used to control cooling water outlet temperature or flow of cooling water, glycol, or other cooling media in applications requiring economical removal of heat from equipment or a process. Since ECONO/HAT-RA valves open on rising temperatures, they can be used in many other thermal relief valve applications. These pump thermal relief valves save space, install in seconds, and eliminate the use of extra, expensive, and time-consuming piping. The unique ram-type plug & seat provide reliable, tight shut off longer than any other design available.
