Our company's D673H\D671X pneumatic butterfly valves are the standard choice for pipeline applications. They are typically categorized into pneumatic butterfly valves with soft seals and pneumatic butterfly valves with hard seals. These pneumatic butterfly valves feature a simple structure, low flow resistance, linear flow characteristics, and no debris retention. They also offer the advantages of being lightweight, easy to install, and requiring low torque to drive. They can be used for both cutting off media and regulating the flow rate of media. The valve body can be fitted with components made from different materials and equipped with seals made from various materials to accommodate different media and operating conditions, optimizing cost and performance. The pneumatic butterfly valves with soft seals are suitable for temperatures up to 120℃ or 150℃. The pneumatic butterfly valves with hard seals are suitable for temperatures of 200℃ or higher and up to 450℃, with nominal pressure up to 1.6MPa. They are used in industries such as water supply and drainage, sewage, food, heating, gas, marine, hydropower, metallurgy, energy systems, and light industry and textiles. They are particularly suitable for applications requiring bidirectional sealing and for valve bodies prone to rust, where they are used to regulate flow rates and cut off media.

Pneumatic Wafer Butterfly Valve - Product Features

Compact and lightweight, easy to disassemble and maintain, and can be installed at any location.
(2) Simple and compact structure, low operating torque, quick 90° rotation to open.
(3) Flow characteristic tends to a straight line, with good regulating performance.
(4) The butterfly plate and valve stem connection utilizes a pinless structure, eliminating potential internal leakage points.
(5) The butterfly plate's outer diameter features a spherical design, enhancing sealing performance and extending the valve's lifespan. It can operate with pressure and still maintain zero leakage after more than 50,000 cycles of opening and closing.
(1) Sealing parts are replaceable and provide reliable double-sealing.
(7) Butterfly plates can be coated with a finish as per customer requirements, such as nylon or polytetrafluoroethylene.
