225APA0176B

The 225APA0176B servo valve belongs to the Servo Valves series and is produced by Vickers for precise hydraulic automation. It meters fluid to control actuator position or speed in systems such as presses or injection machines. The unit does not include a communication input, so valve commands are delivered strictly through electrical coil drive without embedded fieldbus conversion. A maximum flow rate of 100 l/min supports medium-capacity circuits that need rapid cylinder movement. The valve sustains up to 350 bar, enabling operation in high-pressure manifolds. SAE ports provide standard connection threads for easy line routing with common hose fittings. Through holes are provided for mounting, letting the body be bolted directly to a subplate or manifold block. The ductile iron housing resists fatigue and shock loads encountered in industrial service. A configuration with four sections separates control stages to enhance response consistency across the spool stroke. The assembled valve weighs 58.3 lb, which contributes to vibration damping once the unit is fixed in place.

The valve remains functional in ambient temperatures down to −40 °C, permitting outdoor or refrigerated installation, and it tolerates surrounding air up to 60 °C so panel heat does not cause derating. Hydraulic fluid may enter as cold as −25 °C to accommodate low-temperature startup, while a ceiling of 80 °C protects seals during continuous duty. A body length of 13.73 in helps distribute porting and pilot passages without restricting service space inside compact power units. The width of 10.64 in maintains a stable footprint that aligns with standard manifold pads. Overall height is 6.43 in, allowing the valve to clear adjacent components in stacked assemblies. Internal cavity volume of 939.341 in³ provides room for spool travel and damping chambers that smooth pressure transients. These dimensional and thermal limits define where the 225APA0176B can be mounted and how it will behave under varying environmental and fluid conditions.
