These Dynex relief valves provide consistent and accurate control of pressure regardless of flow variations. The design features a hydraulically balanced spool controlled by an integral pilot valve. With a narrow differential between cracking pressure and full flow, these valves are ideal for systems requiring constant actuator force. Pressure is manually set by turning the maximum pressure adjustment knob. Turning clockwise increase pressure. The setting is held by a locknut.
