116-1895: Direct Operated Relief Valve

Description: A hydraulic relief valve is a device used in hydraulic systems to control or limit the pressure of fluid within the system. It is a safety device that prevents damage to the system or equipment due to excessive pressure buildup by diverting excess fluid flow back to the reservoir or tank. Attributes: • Provide precise control over the flow of fluid in a hydraulic system. • Have a Quick response time. Applications: The relief valve typically consists of a valve body, a spring-loaded poppet, and an adjustable pressure setting. When the pressure in the hydraulic system exceeds the set pressure, the valve opens, allowing fluid to bypass the system and return to the reservoir. This relieves the pressure and prevents damage to the system or equipment and it is widely used in Cat 436C, 446, 446B, and 446D Backhoe, D10T, D9R, and D9T Track Type Tractor.
