Double Flange Butterfly Valve Introduction

The Double Flange Butterfly Valve is a highly efficient and reliable valve designed for industrial use. With its unique design, it allows for precise flow control and reduces the risk of leakage. Made with durable materials, it offers long-term performance and minimal maintenance. Experience improved productivity and cost savings with this essential component for any industrial system.

The main features of flange butterfly valve are:

Small and lightweight, easy to disassemble and maintain, and can be installed at any position.
Simple and compact structure, small operating torque, 90 ° turn to open quickly.
flow characteristics tend to straight line, good regulation performance.
The connection between butterfly plate and valve stem adopts pinless structure, which overcomes the possible internal leakage point.
butterfly plate outer circle using spherical modeling, improve the sealing performance and extend the service life of the valve, with pressure opening and closing more than 50,000 times still maintain zero leakage.
The sealing parts can be replaced and the sealing is reliable to achieve two-way sealing.
Butterfly plate can be sprayed with coating according to user requirements, such as nylon or PTFE.
Drive mode can be manual, electric or pneumatic.

Flange butterfly valve is suitable for temperature ≤ 120 ℃ or ≤ 150 ℃, nominal pressure ≤ 1.6MPa water supply and drainage, sewage, food, heating, gas, ships, hydropower, metallurgy, energy systems and textile and other industries, especially for two-way sealing and the valve body is easy to corrosion occasions, as a flow control and interception of the medium.

Note: The prices marked are for 2-12 inch handle flange butterfly valves, and for 14-48 inch are worm gear flange butterfly valves.
