产品介绍
The Pneumatic Tetrafluoro Butterfly Valve adopts a PTFE-lined butterfly plate with a spherical sealing surface. The valve is light in operation, tight in sealing performance and long in service life; it can be used for quick cutting or regulating flow. Suitable for applications requiring reliable sealing and good adjustment characteristics. The valve body adopts a split type, and the seal at both ends of the valve shaft is controlled by a rotating base surface between the disc plate and the valve seat plus fluororubber; the valve shaft is not in contact with the fluid medium in the cavity.
产品特点
1. The design is novel, reasonable, unique in structure, light in weight, and quick to open and close.
2. The operating torque is small, easy to operate, labor-saving and smart.
3. Can be installed in any location, easy to maintain.
4. The seal can be replaced, the sealing performance is reliable to achieve two-way seal zero leakage.
5. The sealing material is resistant to aging, corrosion and long service life.
