Main Feature

1) The seat ring uses the floating seat ring structure with O-seal ring sealed and pre-tightening force applied to have inlet and outlet dual-way sealed, and the open-close moment with this structure is 1/2 that of the common valves only, able to lightly open and close valve.
2) When fully opened, the valve’s channel is smooth and linear,with an extremely small flow resisting coefficient and no pressure loss ,and the pipeline can be cleaned with hair-ball through it .
3) Automatic removal of the high pressure in the internal cavity when the valve is about to close so as to ensure safety.
4) Fully sealed structure leaves a good protective property, suitable for the requirement of 24-hour duty.
