The KTG4V52B50NZMUH730 valve is part of the Proportional Valves series from Vickers and is installed to modulate hydraulic actuator speed and force. It is solenoid controlled, so a 24 VDC coil converts electrical signals into spool movement for precise flow adjustment. The coil is housed at the B port end, which simplifies wiring in manifolds where that side faces the control cabinet. An ISO 4400 (DIN 43650) connector provides a quick-release electrical interface for maintenance and replacement. The valve bolts to an ISO 4401-05 (NG10) subplate, allowing interchange with other NG10 components in a circuit. Meter-in/meter-out metering lets designers balance acceleration and deceleration by throttling flow in both directions. The hydraulic body withstands up to 315 bar, so it can operate in high-pressure mobile or industrial power units without external pressure reducers.
At rated conditions the B port passes 50 L/min, supplying cylinders or motors that need moderate volume without cavitation. The flow path is sized for anti-wear hydraulic oils and non-alkyl phosphate esters, ensuring compatibility with common mineral and fire-resistant fluids. System cleanliness must reach ISO 17/15/12 to prevent spool sticking and to maintain proportional accuracy. There is no feedback sensor on the valve, so position control relies on the driver card and calibrated current. A manual override is not fitted, which prevents accidental spool shifts during service. The design also omits on-board electronics, keeping heat away from the hydraulic block and allowing remote mounting of the driver. Physical dimensions are 194.564 mm in length, 106.172 mm in height, and 70.104 mm in width, so the valve fits standard stack heights in NG10 manifolds.
