PRODUCT DETAILS
The D71X Wafer Butterfly Valve is a compact, soft-seated valve designed for reliable isolation and flow control in commercial and industrial pipeline systems.
Its wafer-style body is installed between pipeline flanges, helping reduce installation space, overall weight, and material requirements compared with conventional flanged butterfly valves. The centerline concentric design provides simple quarter-turn operation, low flow resistance, and reliable sealing for compatible media.
Different body, disc, stem, and seat material options are available to meet specific operating conditions. Manual lever, worm gear, electric actuator, and pneumatic actuator configurations can also be supplied according to application and project requirements.
