PRODUCT DETAILS
The D341X Worm Gear Flanged Butterfly Valve is a soft-seated centerline butterfly valve designed for reliable isolation and flow control in commercial, municipal, and industrial pipeline systems.
Its flanged body provides a strong and stable pipeline connection, making it suitable for larger valve sizes and applications where rigid mounting and easier alignment are preferred. The centerline concentric design provides simple quarter-turn operation, low flow resistance, and reliable sealing for compatible media.
The worm gear operator provides mechanical advantage, helping reduce manual operating force for larger valve sizes and higher torque requirements. Lockable gearbox and extended stem options may also be available according to project requirements.
