VR4V 03 / 06 / 10 Series

The Veljan Pressure Relief Valve series VR4V are pilot operated and work on the principle of hydraulic balancing. These valves are used to limit the system pressure in a hydraulic system and protect the system against pressure overload. Accurate pressure control even under wide flow variations are achieved by these valves.

The valves may also be used to generate a pressure drop in a hydraulic circuit. VR4V consist of a high flow poppet type seat valve section controlled by the low flow, adjustable pilot section mounted on top. Pressure setting is achieved by means of knurled knob. For tamper proof setting, an acorn nut with lead seal is available as option. Optional vent valve VVV01sandwiched between pilot section and the main body can be used for venting the VR4V valves.

Exceptionally fast response is obtained due to the precise ratio between the main piston area and its mass. High pressure stability is an out standing feature of VR4V valves.
