The sealing function of BK3 and SK3 valves is only given when the pressure standing on the closed port is zero or if the pressure between the connected ports is higher than the pressure on the closed port. No shut -off position for third port is possible! To apply pressure from all ports, a special variant is required. Add A to the order code.
