The RCT03A320 valve belongs to the Pressure Control Valves series produced by Vickers for hydraulic automation systems. It is pilot operated, allowing a small pilot flow to modulate the main orifice and stabilize circuit pressure. The design follows size 03 standards and employs a two-stage layout that combines a pilot element with a larger main stage for smooth response. A cast iron body provides mechanical strength, while a working limit of 3000 psi (210 bar) and a flow capacity of 12 gpm (45 L/min) cover many medium-duty circuits. Porting is 3/8 NPT, and the same 3/8 in NPT thread mount secures the unit to piping or manifolds. Because adjustment and feedback are purely hydraulic, the valve includes no electrical connection points.
An internal check valve permits reverse flow when required and prevents unwanted backpressure during normal regulation. Nitrile (Buna-N) seals withstand exposure to petroleum oils, matching the stated fluid compatibility. Reliable service depends on maintaining fluid cleanliness at ISO 4406 code 19/17/14 or cleaner to protect the pilot passages. The assembly operates in oil or ambient temperatures from -20 °C (-4 °F) to 70 °C (158 °F), so it can be installed in cold storage areas or warm machine bays without modification. When these temperature and cleanliness limits are respected, the valve maintains accurate pressure control throughout its operating range.
