1. Rexroth relief valve

Overflow, pressure stabilizer, which is used to regulate and maintain the oil supply pressure of the pump while overflowing the excess oil in the system. When the regulated pressure is reached, the hydraulic system is controlled to keep it in a constant state. Relief valves for overload protection are called safety valves. If the system fails, and the pressure rises to a limit value that can cause damage, the valve opening opens and overflows, ensuring the safety of the system.

2. Rexroth pressure reducing valve

This results in a stable pressure in the branch circuit, which is lower than the oil pressure in the main circuit. According to its function of controlling pressure, the pressure reducing valve can be further divided into a fixed value pressure reducing valve, a differential pressure reducing valve and a fixed ratio pressure reducing valve, wherein, the constant value pressure reducing valve has a constant output pressure, the differential pressure reducing valve has a fixed difference between the input pressure and the output pressure, and the fixed ratio pressure reducing valve has a fixed ratio between the input pressure and the output pressure.

3. Rexroth sequential valve

A sequential valve is a pressure valve that uses pressure as a control signal to automatically turn on or off a specific oil circuit. Because it is commonly used to control the sequence of movement of actuators, it is called a sequential valve.

Rexroth sequential valves are capable of actuating one actuator (e.g. hydraulic cylinder, hydraulic motor, etc.) followed by other actuators.
