Pressure Check Valve
聽
Introduction
聽
Pressure check valves enable the regulation of system pressure to adjust the force on a hydraulic piston rod or the torque on a hydraulic motor shaft. Pressure relief valves are used to set the maximum pressure in the circuit and protect it from overloading. Pressure reducing valves permanently maintain the output pressure at the set value while protecting the appliance from overloading. Unloading valves are designed for economical pressure control in accumulator-operated circuits that serve as a power source for emergency control.

Features
聽
Different types of pressure control check valves include relief, reducing, sequence, counterbalance, safety, and unloading. All of them are typically closed valves, except for reducing valves, which are usually open.
聽
Pressure Relief Valves regulate oil flow or system pressure and limit maximum pressure. They help to provide additional operator and component safety.
