CT10B30

The CT10B30 relief valve is produced by Vickers as part of the Pressure Control Valves series. It protects hydraulic circuits by opening when system pressure reaches a preset limit, making it suitable for automation pressure regulation. A balanced piston mechanism keeps the opening force consistent despite downstream variations, which stabilizes the relief point. The nominal size 10 body defines passage areas sized for medium-flow installations. Circuit plumbing connects through a 1-1/4 in port that uses NPTF threads, ensuring compatibility with common steel pipe fittings and minimizing leakage paths. These interface details simplify mounting and allow the valve to be inserted quickly into existing manifolds or line bodies.

The valve follows the standard vent configuration, which means pressure adjustment is carried out locally rather than through an external pilot line. Because no sequence feature is present, the unit operates solely as an over-pressure safeguard and does not coordinate multiple actuator stages. A fluid cleanliness requirement of ISO 18/15 limits particulate contamination and helps the internal moving parts seat reliably after each cycle. Installation planning is aided by the rectangular envelope: the body measures 182.626 mm in length, 83.312 mm in width, and 156.972 mm in height, dimensions that fit easily inside typical power unit frames. These metrics let designers allocate space accurately and maintain correct service clearances around the valve.
