This product is subject to the combination of ball valve and butterfly valve, the main structure similar to butterfly valve, the valve core for part of the sphere
which take ball valve core part of the real effective near the sealing surface, as part of the seat for the ring body, valve core center of rotation is different from a sphere center. Profile is visible on the sphere surface contact with ring cone with the pedal is not formed by the center points and the ball ring cone vertical profile, in other words, the valve seat sealing surface is not a sphere A continuous surface of a line. With reverse pressure or reverse the role against the differential pressure is greater than the positive effect when, seating series of dynamic self-compensation seal clearance, to two-way sealing. The more pressure, the better the effect of the bidirectional seal.
