The Prefill Exhaust Valve (PV) is a hydraulic-pilot operated check valve with seat type construction. It allows free flow from port A to port B. Flow from port B to port A can be enabled by applying pilot pressure to it’s port X. The decompression feature enables the valve to open in two stages progressively, allowing smooth and rapid exhaust of the compressed oil. Opening and closing time of the valve can be influenced by providing Throttle-Check Valves in the X port line. Flanged port A of the valve housing can be rotated around vertical axis through 360° to facilitate access to flange fixing bolts and flange orientation. kindly refer the catalogue for ordering code and technical specification.
