Operation
The TBV-PR integrates temperature control and pressure relief into one valve. The thermal actuator of the thermal bypass valve precisely adjusts the opening based on temperature fluctuations to control flow and ensure optimal system performance. Cooler fluid goes through the valve bypass, while hotter fluid goes through the system’s heat exchanger/cooler.
The built-in pressure relief function safeguards the system from excessive pressure buildup. When the pressure exceeds a predetermined threshold, the valve opens, allowing fluid to escape and reducing pressure to a safe level. Refer to the Bypass Mode with H/X path blocked graphic below.
This versatile valve can be incorporated into a 4-way manifold to efficiently direct fluid flow based on temperature, ensuring optimal system performance and safety.
