VR4R 03 / 06 / 10 Series
Veljan Pressure Reducer Valve Series VR4R are pilot operated controls used to control pressure in a secondary part of a hydraulic circuit. Pressure is maintained as set by control knob on the pilot or by an external pilot source.
Product Description
In some application,VR4R is used to maintain a lower pressure in the secondary circuit to limit the force available from certain actuators.
VR4R consists 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 a knurled knob. For tamper proof setting, acorn nut with lead seal is available as an option. Optional vent valve VVVO1 sandwiched between pilot section and main body can be used for venting the VR4R valves.
Extremely accurate settings can be obtained due to the precise construction of control components. The design of poppet allows for the minimum of friction and hysteresis giving a sensitive response to conditional changes.
