Thermal Bypass Valve

Thermal Bypass Valve

Type

Accessories

 

An optional feature for the MAR and BOLR Series – thermal bypass and pressure relief features combined in one valve. Temperature bypass is activated (closes) when oil reaches a defined set point of 110° F and allows full oil flow through the heat exchanger. When the oil is cool, the valve is open to allow a partial flow bypass.

Function

Thermostatically activated, these valves route partial, cold oil flow around the heat exchanger to limit backpressure and unwanted cooling of oil during cold start-up situations. When the oil is cold (<110°F, 43°C), the internal valve connection P-T is open directing flow around the cooler with minimum pressure loss and enabling the oil temperature to increase to operating temperature. Once this temperature is reached (>110°F, 43°C), the thermal wax element closes the P-T connection and full flow is directed through the heat exchanger. The integrated pressure relief valve, set at 60 PSI, also helps safeguard the cooler from occasional return-line flow surges.

3D Model Coming Soon.

Our 3D Product Configurator will allow you to build up the cooler with specific options that are required for your application, view what you have created in 3D, then download the model directly into your format to complete your modeling project.
