Hydraulic Relief Valves

USE AND OPERATION
The relief valve limits the maximum pressure in a circuit to the valve's setting.
When the circuit pressure reaches the setting, the valve opens and stops the circuit pressure going any higher.
MATERIALS AND FEATURES
Body: zinc plated steel.
Internal parts: hardened and ground steel. Seals: BUNA N standard.
Leakage: Guided poppet negligible leakage.
Oil temperature: 50° C - Oil viscosity: 30 cSt
CONNECTIONS
Connect circuit port with pressure to P and tank port to T. Port P is reversible.

USE AND OPERATION
Made up by two cross port relief valves, these valves ore used to limit the pressure in the both ports of a hydraulic motor to a certain setting.
Direct flange mounting for orbital motors type OMP-OMR provides maximum safety, very low pressure drop and a robust installation.
MATERIALS AND FEATURES
Body: zinc-plated steel.
Internal parts: hardened and ground steel.
Seals: BUNA N standard.
Leakage: Guided poppet - negligible leakage.Oil temperature: 50° C - Oil viscosity: 30 cSt
CONNECTIONS
Flange M1 and M2 directly to the motor and connect ports V1 and V2 to the supply.

USE AND OPERATION:
Made up from two cross line relief valves, this valve is used to limit the pressure to a certain setting in the two ports of a cylinder/hydraulic motor. It's ideal to provide protection against sudden shock pressures or to limit the maximum pressures in the two ports of a hydraulic circuit.
MATERIALS AND FEATURES:
Body: zinc-plated steel.
Internal parts: hardened and ground steel.
Seals: BUNA N standard.
Leakage: Guided poppet - negligible leakage.
CONNECTIONS:
Connect V1 and V2 to the pressure flow or to the cylinder/ hydraulic motor. Vice versa for the remain-ing ports V1 and V2. Mounting close to the cylinder is highly recommended in order to avoid pressure drops and to have a fast response.
