Thermal Bypass Valve

Maintain Optimum Fluid Temperature

Parker’s thermal bypass valve will modulate fluid temperature by shifting return line flow through the cooler, or bypassing it directly to the reservoir.

Additionally, an integral pressure relief function automatically releases excess pressure to the reservoir if the cooler becomes restricted, and the inlet pressure becomes excessive. Relief crack pressure settings range from 5 to 85 PSI.

These lightweight, aluminum valves are ideal for hydrostatic drive circuits requiring fast warm-up, controlled fluid temperatures, and low return line back pressure.

Features

• Lightweight, corrosion-resistant aluminum housing.
• Available in five shift temperatures.
• Integral relief valve to dump excessive inlet pressures to the reservoir.
• 250 PSI maximum operating pressure.
