Cartridge relief valve Marchesini DRV-S10-02

These values come from the manufacturer's published data. The full list is in the specifications tab.

Applications

• Overload protection of the circuit
• Hydraulic blocks
• Compact power units

How it works

A pressure control valve works against an adjustable spring. When circuit pressure overcomes the spring force, the valve opens and sends excess oil to tank or another line, so pressure stays at the set value and the pump and actuators are protected from overload.

Selection and maintenance

Choose the setting range and flow to match the circuit. Set pressure only with a gauge and under safe conditions. Pressure loss or swings usually come from a worn seat, a tired spring or dirt particles, and a valve that stays open keeps heating the oil.
