The 280 series stainless steel hydraulic rotary control valves are designed for control of hydraulic actuators in hostile environments where internal leakage must be minimized. They use an optically flat rotary spool with pressure-loaded seats to ensure near-zero internal leakage. The valves are easily configured to application requirements and come in six standard flow patterns, three sizes, three types of hydraulic seal side ports, and with manifold O-ring port, straight or cranked handle, spring-center or detent action. The valves are rated for maximum pressure to 700 bar (10,000 psi), maximum flow to 38 lpm (10 gpm) and meet ATEX directive BS EN 13463-1:2009.
