Industrial Butterfly Valves — Manufacturer, Supplier & Stockist
Butterfly valves use a rotating disc mounted on a shaft to control flow, offering a compact, lightweight and cost-effective solution for both isolation and throttling. Navjivan Valves supplies wafer, lugged, double-flanged and high-performance butterfly valves across a wide range of sizes.
Product Overview
Butterfly valves take up far less space and weight than gate or globe valves of equivalent size, since the disc rotates within the pipe bore rather than lifting clear of it. Quarter-turn operation allows quick opening and closing, and the design scales efficiently to large diameters, making butterfly valves popular for water treatment, HVAC, and general isolation duty across many industries.
Types of Butterfly Valves
High-Performance Butterfly Valves (HPBV)
Available in concentric, double-offset and triple-offset configurations, with triple-offset designs offering the highest sealing integrity for demanding, high-pressure or high-temperature service.
Wafer-Type Butterfly Valves
Fit between two pipeline flanges without their own separate flange, using the flange bolts to hold the valve in place — a compact, economical choice for general isolation.
Double-Flanged Butterfly Valves
Feature their own flanged ends on both sides, simplifying installation and removal without disturbing the rest of the pipeline — favoured on larger diameters and higher pressure lines.
Lugged Butterfly Valves
Use threaded lugs cast into the body so the valve can be installed as an end-of-line valve or removed for maintenance without depressurising the whole pipeline.
