KFTG4V52B50NZMU1H720

The KFTG4V52B50NZMU1H720 proportional valve belongs to the Proportional Valves series produced by Vickers and is intended to regulate hydraulic flow and pressure in automation systems. It relies on solenoid-controlled actuation, so coil energization shifts the spool to meter oil without mechanical linkage. The 24 V DC coil voltage aligns with standard machine power supplies, simplifying electrical integration. A B-port flow rating of 50 l/min (13.20 US gpm) defines the maximum volume the valve can pass while maintaining stable control. System designers can operate up to 315 bar (4500 psi) because this is the stated maximum pressure the unit can withstand. Metering is available on both the meter-in and meter-out sides, allowing symmetrical throttling during cylinder extension and retraction. The body mounts on an ISO 4401-05 (NFPA D05/CETOP 5/NG10) interface, so it fits directly onto commonly machined subplates.

Physical dimensions are fixed at a height of 106.172 mm (4.180 in) and an overall length of 10.830 in, figures that assist when planning manifold spacing or enclosure depth. The valve carries no onboard electronics, therefore a separate amplifier must generate the driving current for the solenoids. Because a manual override is not provided, technicians cannot shift the spool by hand during commissioning or power loss. The specification lists no command input, indicating that proportional control is achieved solely through the coil current rather than an integrated feedback port or potentiometer. Likewise, there is no communication protocol, so the component cannot exchange data with fieldbus networks and remains a purely analog device. These traits define a straightforward flow-control element that depends on external electronics for precise positioning.
