PILOT OPERATED PRESSURE CONTROLS - FLANGED TYPE VR5 Series

nnnn

r) ri

nnnn

Veljan Flanged type, Valves Series VR5V( Relief ), VR5U (Unloader]

nnnn

and VR5S (Sequence ) are pilot controls. These range of valves are

nnnn

suitable for mounting directly on a SAE Pump outlet flange, ensuring

nnnn

maximum pump protection against peak pressure and eliminating

nnnn

costly piping. The pilot stage of VR5 valves are designed to reduce

nnnn

pressure overshoot and minimise cracking flow, thus reducing

nnnn

power and production losses during high pressure operation .

nnnn

VR5 valves consist of a high flow poppet type seat valve section

nnnn

controlled by the low flow, adjustable pilot section mounted on top.

nnnn

Pressure setting is achieved by means of a knurled knob.

nnnn

For tamper proof setting, acorn nut with lead seal is

nnnn

available as option. Optional Vent Valve VWO

nnnn

sandwiched between pilot section and main body can be

nnnn

used for venting the VR5 valves.

nnnn

Exceptionally fast response is obtained due to precise

nnnn

ratio between main piston area and its mass. High

nnnn

accuracy and quiet, flutter free control are the important

nnnn

characteristics of VR5 valves.

nnnn

VR5V Pressure relief valves are used to limit the pressure of

nnnn

a hydraulic system. The VR5V may also be used to

nnnn

generate a pressure drop in a hydraulic circuit. Normally

nnnn

port A is connected to pump and port B to tank.
