Bidirectional Pilot-Operated Valve

Pilot-operated valves use upstream pressure to open and close the main valve. Conventional pilot-operated valves offer distinct advantages, including significantly reduced actuator size, lower weight, and decreased power consumption. However, they can only control fluid flow in the forward direction, from the IN port to the OUT port. To overcome this limitation, our company has developed a new pilot-operated valve capable of controlling flow in both forward and reverse directions. It is ideal for applications that require switching flow direction depending on the operating phase. For example, it enables fluid control in both charging and power-generation modes in reversible water electrolysis and fuel-cell systems. Despite its compact height of 109 mm, the sample product provides a high flow rate with a Ø10 mm orifice and withstands pressures of up to 1 MPa in both directions. Orifice size, pressure rating, and materials can be customized upon request. Note: Details such as specifications, etc., may be changed without notice.
