The Parker Double Throttle check valves feature a sandwich design, making them ideal for easy configuration in stack systems. The throttle and check valves are integrated into the A and B ports. These valves can be used to influence the switching time of pilot operated directional valves by positioning the throttle check valve between the pilot stage and the main stage. This configuration allows for precise control over fluid flow and switching times, enhancing the performance of hydraulic systems. Metering needle design allows a very wide range of flows to be suitable for all applications
Large bypass check valves allow high flow at low pressure drop
