Check Valves

Check Valves - C
These seat type valves allow free flow from port A to port B and give leak-proof closure in opposite direction. Available as inline mounting or Sub-plate mounting as per factory & ISO standards.

Check Valves, SCREW-IN CARTRIDGE - KSC / KSD
Two port screw-in cartridge valves that are designed to fit in a cavity confirming to ISO 7789 : 1998 (E). These are seat type vales, available in four different sizes and with five different cracking pressure in each size. Check valves allow free flow in one direction while providing leak-free closure in reverse direction.
Features
• Fits into ISO 7789 : 1998 (E) cavity. (other cavities available on request)
• Cartridge construction for compact integrated manifolds
• Economical
• Quick and Easy field service, reduces down time
• Valve Bodies available on request

Check Valves - C (ISO)
Seat type valves. Allow free flow from port A to port Band offer leakage free closure in opposite direction. Available in four sizes of standard interfaces conforming to
ISO 5781
IS 10187
DIN 24340
Each model available with options of four cracking pressures : 0.5, 1.5, 3 and 5 bar.

Check Valves - CI
Seat type valves, Model CI with internal drain. Threaded or Sub-plate mounting construction. Available with two pilot piston size options only for Model CI.

Check Valves - CI06
Seat type valves, Model CI with internal drain. Threaded or Sub-plate mounting construction. Available with two pilot piston size.

Check Valves - CL
Seat type valves, CL with external drain. Threaded or Sub-plate mounting construction.

Check Valves - 2CI
These valves are available with the pilot operated check valve facility on either A or B or both A and B threaded ports. The hydraulic opening operation for free flow in reverse direction is achieved by means of internal pilot pressure available from the other working port.

By-pass Check Valves (Modular) - BCM
Seat type modular valve. Intended for by - passing. Pressure control valve,Pressure reducing valve etc. to achieve reverse free flow condition.Allow free flow from port A to port B or from port B to port A ( see model code ) and offer leakage free closure in opposite direction. Available in four sizes of standard interfaces conforming to ISO 5781, DIN 24340 or IS 10187 Each model available with options of four cracking pressures : 0.5, 1.5, 3 and 5 bar.

Pilot Operated Check Valves (Modular) - CIM 06
These modular valves are available with the pilot operated check valve facility on either 'A' or 'B' ports. The hydraulic opening operation for free flow in reverse direction is achieved by means of internal pilot pressure available from the other working port. Interface conforming to
ISO 4401-AB-03-04-A
IS 10187
DIN 24340
To ensure proper closure of both valve poppets, both user connections should be unloaded when the control valve is in the neutral by connecting with the return line.

Pilot Operated Check Valves (Modular) - CIM 10
These modular valves are available with the pilot operated check valve facility on either A or B or both A and B ports. The hydraulic opening operation for free flow in reverse direction is achieved by means of internal pilot pressure available from the other working port.   To ensure proper closure of both valve poppets, both user connections should be unloaded when the control valve is in the neutral position by connecting with the return line.

Shuttle Valves - SL
Seat type construction. Automatically connects it's P port to either A or B depending upon whichever of the two ports is at higher pressure level. Isolates port A and B from each other. Port P gets connected to tank, only if, port A and port B are connected to tank. Available both in Threaded and Sub-plate type.

Prefill Valves ( PV 32 - 80 )
Intended for prefilling and exhausting of large hydraulic cylinders. Can be used as anticavitation check valves. Decompression feature is optional up to size 80.

Prefill Valves ( PV 100 - 200 )
Intended for prefilling and exhausting of large hydraulic cylinders. Can be used as anticavitation check valves.

Prefill Valves ( PV 100 - 200 ) - 21 Series
The Prefill Exhaust Valve (PV) is a hydraulic-pilot operated check valve with seat type construction. It allows free flow from port A to port B. Flow from port B to port A can be enabled by applying pilot pressure to it's port X. The decompression feature enables the valve to open in two stages progressively, allowing smooth and rapid exhaust of the compressed oil. Opening and closing time of the valve can be influenced by providing Throttle-Check Valves in the X port line. Flanged port A of the valve housing can be rotated around vertical axis through 360° to facilitate access to flange fixing bolts and flange orientation
Features
• Integrated Seat provides high rigidity, high fatigue resistance and less deflection of the flange.
• Encapsulated O-ring allows easy of assembly and prevents o-ring damage during assembly.
• Simplified Cavity machining
• Larger suction flange to reduce pressure drop in the suction line and consequently increase flow handling capability
• Improved Pilot cylinder sealing to minimize pilot leakage and reduce frictional loss during operation.
