Characteristics:
Reliable sealing method.
The sealing ring can be replaced directly on the valve.
The material of valve seat is stainless steel.
The valve uses streamline design, which act the fluid with small resistance.
The sealing ring uses imports rubber vulcanization, which is good elasticity and long life.
Profile:
The traditional butterfly valve uses the way that the wheel rim compressing the sealing rings. Because when the screw looses or the sealing ring shifts they will cause leaking, so the sealing ring is set on the valve directly of this series butterfly valve. It is connected with the valve by barb, which overcome the leakage characteristics of the traditional butterfly valve.
