Relief valve – Balanced piston type pilot operated (1) With shock damping valve (Y) X P T Relief valve – Balanced piston type pilot operated (1) Overview This balanced piston type pilot operated relief valve, which is a seat type relief valve, regulates the highest pressure of the hydraulic circuit and at the same time prevents overload of the hydraulic equipment and drive machines and sets pressure for control of the hydraulic equipment. The relief valve with unloading function is used for loading and unloading the circuit pressure with electrical signals. Type indication RB Features 1. As this valve has a larger seat diameter than that of a general balance type relief valve, it has good responsiveness and flow resistance when unloaded is small. 2. Pressure override is small. 3. Operation is correct and both responsiveness and stability are good. 4. The relief valve with unloading function can perform shockless, smooth unloading if it is used together with the shock damping valve (refer to the section of the type number index “ZNS5”).
