PRODUCT DETAILS
The D371X Worm Gear 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 dependable sealing for compatible media.
The worm gear operator provides mechanical advantage, helping reduce manual operating force for larger valve sizes and applications with higher operating torque. Lockable gearbox and extended stem configurations may also be available according to project requirements.
