Worm Gear Lug Butterfly Valve

Description :-

Overview
A Worm Gear Lug Butterfly Valve combines the robust flow control capabilities of a butterfly valve with the precision and torque advantages of a worm gear actuator. The lug design features raised lugs on both sides of the valve body that allow the valve to be bolted directly to pipeline flanges, enabling one-side installation or removal without disturbing the opposite flange. The worm gear mechanism provides mechanical advantage, allowing easy manual operation and precise flow regulation in low to medium pressure systems.

Key Features

Construction: Valve bodies typically made from ductile iron, carbon steel, or stainless steel with discs in stainless steel (SS316) and shafts in SS410 for corrosion resistance and durability.
Actuation: Manual worm gear operator offers controlled, low-effort valve operation with self-locking capability to hold valve position securely.
Pressure Rating: Commonly rated around PN10 to PN16 (10–16 bar pressure), suitable for diverse industrial applications.
Sealing: Rubber or soft seats with excellent corrosion and wear resistance provide reliable leak-tight closure.
Installation: Lugged ends allow for flange bolting on both sides, permitting installation and removal from one side of the pipeline, ideal for dead-end systems.
Size Range: Available in sizes from DN50 (2″) up to DN600 (24″) or larger, catering to various piping sizes and flow rates.
Applications: Used extensively in petrochemical plants, thermal power stations, water treatment, HVAC systems, and other industrial pipeline applications requiring dependable isolation and flow control.
