BFR5K150SK2PTS12 Cartridge Flow Control Valve Unit

Module Feature

BFR5K150SK2PTS12 is a screw-in cartridge flow control valve for industrial hydraulic systems.

It adopts cartridge insert design for installation inside standard valve manifold cavity. It is equipped with built-in pressure compensator to keep stable flow output when upstream pressure fluctuates. The model integrates pressure and temperature test ports for on-site inspection and adjustment. It is widely used in hydraulic stations, plastic injection equipment and metal forming machinery for flow regulation and speed control of hydraulic actuators.

Working principle

The internal spool and compensator assembly automatically adjust the opening gap.

When inlet pressure changes, the compensator spool moves to maintain constant pressure difference across the fixed orifice, so the output flow keeps stable regardless of load variation. The adjustment screw can set the required flow rate according to process demand.

Onboard components

Valve sleeve, metering orifice spool, pressure compensator spring, adjusting screw, O-ring sealing set, pressure/temperature test passage.

LED indicators

Not applicable.

Hardware self‑diagnosis

No built-in electronic self-test. The performance is checked by pressure gauge, flow meter and actuator running speed.

Programming software

Not applicable.
