1. Self contained thermal actuator2. Reverse action
3. Sensitive to temperature only
4. Easy installation with pipe wrench
As the fluid temperature increases to within the operating range of the SP42, the thermal actuator modulates the valve open. If the fluid temperature is above the acceptable range, the valve will continue to modulate open allowing additional fluid discharge. As the outlet temperature falls slightly, the valve then modulates toward the closed position, reducing flow. This modulating action maintains a relatively constant fluid temperature even as operating conditions vary.
The model SP42 reverse action valve can be used to regulate the flow of cooling water, glycol or other cooling media in applications requiring economical removal of heat from equipment of a process. Since the SP42 valves open on rising temperatures, they can be used in many thermal relief valve applications.
