Main features: The track type ball valve relies on the lifting and lowering of the valve stem to rotate and tilt the ball, which belongs to forced sealing. Therefore, it is designed with a single valve seat, so there is no possibility of abnormal increase in chamber pressure. It can only be used as a switch valve and is very suitable for high temperature, high pressure, frequent operation, zero leakage, emergency shutdown, hazardous medium isolation and other working conditions. Typical application conditions include molecular sieve switching valve, hydrogenation compressor inlet and outlet valve, emergency shutdown valve, metering pipeline shutdown valve, etc.
