The XG033F21 pressure reducing valve belongs to the Pressure Control Valves series and is manufactured by Vickers for hydraulic automation circuits that require stable downstream pressure. It is pilot operated, so a small control flow modulates the main spool to maintain the set pressure even when demand changes. The two stage layout separates sensing from flow handling to improve response. A maximum operating pressure of 210 bar (3000 psi) defines the allowable inlet pressure, and a nominal flow capacity of 53 L/min (14.0 US gpm) indicates the volume it can pass without generating excessive differential. The valve mounts on a subplate or manifold to simplify installation on modular power units, and the size 03 interface matches common CETOP patterns. Because no check valve is built in, designers must add separate blocking components when reverse flow must be prevented. Reliable service requires fluid cleanliness of 19/17/14 to limit contamination-induced wear.
Nitrile seals are fitted to contain hydraulic fluid and remain elastic between −20 °C (−4 °F) and 70 °C (158 °F), allowing the valve to operate in mobile and industrial environments. A 1/4 NPTF gauge port lets technicians connect pressure instruments directly for setup and troubleshooting. Physical dimensions of 6.200 in (157.48 mm) in length, 2.810 in (71.37 mm) in width, and 5.600 in (142.24 mm) in height help designers allocate clearance on crowded manifolds and confirm envelope size against adjacent components. These proportions also aid in predicting mass and support requirements when the valve is installed on lightweight aluminum bases. Together, the temperature range, sealing choice, and dedicated gauge port ensure the XG033F21 maintains accurate pressure reduction over prolonged duty cycles while permitting straightforward monitoring and maintenance.
