Check Valve – 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 Valve (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 valve (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

Pilot operated check valve (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 valve ( 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.
