EPDM Seat PN16 Turbine Cast Steel Manual Double Eccentric Flange Butterfly Valve
Product Introduction
Turbine flange butterfly valve (also known as turbine flange flap valve) generally adopts three eccentric multi-level metal hard seal structure, which is widely used in metallurgy, electric power, petrochemical, water supply and drainage and municipal construction industrial pipelines with a medium temperature of ≤425 °C, and is used to regulate the flow and carry the fluid.
The valve adopts a triple eccentric structure, and the valve seat and disc plate sealing surface are made of different hardness and stainless steel, which has good corrosion resistance and long service life.
Product Advantages:
1. Small and lightweight, easy to disassemble and maintain, and can be installed in any position.
2. The structure is simple and compact, the operating torque is small, and the 90-degree rotation opens quickly.
3. The flow characteristics tend to be straight, and the adjustment performance is good.
4. The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes the possible internal leakage point.
5. The seals are replaceable, and the sealing is reliable to achieve two-way sealing.
6. The butterfly board can be sprayed according to user requirements, such as nylon or PTFE.
7. The valve can be designed as a flange connection and a clamp connection.
8. The driving mode can be manual, electric or pneumatic.
