VR Valves

Oilgear Towler relief valves are used for the control of maximum pressure in hydraulic systems. They can operate accurately over long periods of time without re-adjustment and have low pressure rise between minimum and maximum flow. The unique Oilgear Towler design allows the valve response to be adjusted so that excessive rate of pressure rise can be eliminated and thus shocks and pressure overshoot in the system can be minimized.

The Direct operated range are available for either cartridge or, surface mounting with options for the combination of spool and main spring to cover a wide range of flows and pressures.

The Pilot operated valves have the unique Oilgear Towler design that allows the valve response to be adjusted so that excessive rate of pressure rise can be eliminated. The valves are suitable for pressures up to 500 bar and flows up to 2000 l/min.
