Feature:

• Veljan Pressure control valves are superior in performance and design - even under high flow conditions at maximum operating pressure of 5000 psi (350 bar). Series VR1E02 is a direct operated pressure relief valve designed to control system pressure remotely. Pilot operated pressure control valves series VR4* & VR5* consist of two valve sections: a high flow poppet type seat valve section controlled by the low flow and adjustable pilot section mounted on top. VR4* series are offered for various mounting options, subplate or pipe mounted, or as cartridge assemblies for manifold applications. VR5* series pressure control valves are flange type suitable for mounting directly on pump delivery port thereby minimising piping and saving space. The internal operating components of flange mounted Pressure Controls (VR5* series) are same as those of VR4* series. Pressure Relief Valves (VR4V/VR5V) offer precise and smooth limitation of the system pressure in a hydraulic system. Pressure Unloading Valves (VR4U/VR5U) are used to unload a circuit at preset low pressure when a pilot signal higher than the preset low pressure from external source is maintained (at Port X). This saves considerable energy. Pressure Reducing Valves (VR4R) are used to control reduced pressure in the secondary part of a hydraulic system than its primary part and to maintain this pressure as set by the control knob on the pilot. Pressure Sequence Valves (VR4S/VR5S) are used to operate the hydraulic system in a pressure sequence. After system pressure of the primary part of a system reaches to the preset value of the valve, the valve opens and allows flow to the secondary part of the system. 

Product Details:

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 VVV01 sandwiched 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 outstanding feature of VR4V valves.

Product Details:

Veljan Flanged type, Valves Series VR5V ( Relief ), VR5U (Unloader) and VR5S (Sequence ) are pilot controls. These range of valves are suitable for mounting directly on a SAE Pump outlet flange, ensuring maximum pump protection against peak pressure and eliminating costly piping. The pilot stage of VR5 valves are designed to reduce pressure overshoot and minimise cracking flow, thus reducing power and production losses during high pressure operation . VR5 valves consist of a high flow poppet type seat valve section controlled by the low flow, adjustable pilot section mounted on top. VR5V Pressure relief valves are used to limit the pressure of a hydraulic system. The VR5V may also be used to generate a pressure drop in a hydraulic circuit. Normally port A is connected to pump and port B to tank. Pressure setting is achieved by means of a knurled knob. For tamper proof setting, acorn nut with lead seal is available as option. Optional Vent Valve VVV01 sandwiched between pilot section and main body can be used for venting the VR5 valves. Exceptionally fast response is obtained due to precise ratio between main piston area and its mass. High accuracy and quiet, flutter free control are the important characteristics of VR5 valves.

Veljan Pilot Operated Check Valves VC4V are with pilot control for hydraulic unlocking. These are spring-loaded poppet type valves. Mounting configuration of VC4V are according to International Standards such as CETOP, DIN, ISO or NFPA. Standard versions available are subplate mounting L - body and T - body. VC4V valves can be used as body type units or cartridges for manifold application. VC4V valves have zero-leak condition for flow from port B to port A and free flow in opposite direction. The blocked flow (zero-leak) direction can be unblocked hydraulically via a control piston. A small control piston and stroke is enough to unblock the flow. Thus the low pilot oil volume of 0.64 ml results in a fast response time.

Feature:

• Veljan Seat Valves are body type mounting series VD4S and cartridge units series VCAR. The complete range of cartridges - body mounted VD4S and manifold mounted VCAR are sized from 3/8” to 1 1/2” permit flows from 180 lpm to 600 lpm and pressures up to 350 bar. The interface porting on the subplate body versions follow CETOP, ISO and DIN standards and is dimensionally identical with the VR4 series of pressure controls. Hence VD4S and VR4 valves can be conveniently used in combined circuitry. 

The modular design is used in all valve sizes and the valves are used for a variety of functions : - As a leak - proof directional control A variety of standard combinations of internal components are available along with additional options to suit special circuitry.

These options are

• Poppet stroke limiter : flow rate, - Vent valve sandwiched : to electrically control poppet operation, 
• Seat area changes : to vary operational characteristics, 
• Shuttle valves : To take pilot oil from Port A and Port B. Advantages of VCAR cartridge valves are that when integrated with specially designed manifold blocks they offer space and cost savings in comparison with conventional piped circuit construction. 

 
A manifold design using cartridges is more sophisticated than utilising VD4S units and greater attention is required in the assembly of the cartridges into the manifolds. Fast response and rapid frequency of operation even at the highest flow is achieved due to poppet design and precise ratio between its mass and stroke. The cast passages within the VD4S valve body when used with correctly designed manifolds ensure circuits in which pressure drop and oil turbulence is minimal. Veljan seat valves and cartridges function to direct flow from port A to port B or vice - versa and their operation is dependent upon the effective pressure area and spring force on the poppet. The cracking pressure is proportional to the ratio of control area to seat or ring area. Veljan- As a pressure control for the adjustment or limitation of the pressure - As a check valve to obtain unidirectional flow - As a throttle valve to control and limit the rate of flow
