Butterfly Valves Supplier in Pakistan

Butterfly valves control flow with a disc that rotates a quarter turn inside the pipe bore. Their compact, lightweight body makes them far easier and cheaper to install on large-diameter lines than gate or globe valves, while still giving reliable isolation and regulation. A. Karimjee & Sons supplies butterfly valves for water, HVAC, chemical and industrial piping in wafer, lug and flanged designs.

Types We Supply & How to Choose

Butterfly Valve Types

Selection guide

Wafer: Clamped between two flanges; the most economical design, but the line must be isolated to remove it.
Lug: Threaded lugs let either pipe side be disconnected as a dead end — needed for end-of-line or single-side maintenance.
Double Flanged: Bolted flanges both sides for larger-diameter and higher-pressure lines.
High Performance: Double-offset design for higher pressures and tighter shut-off.

Frequently Asked Questions

What is the difference between wafer and lug butterfly valves?

A wafer valve is clamped between two flanges and needs both sides bolted; a lug valve has threaded lugs so either pipe side can be removed independently, allowing dead-end service.

Are butterfly valves good for throttling?

Yes, within limits — they regulate flow well through the mid-range of travel. For precise throttling at low flow, a globe valve is usually the better choice.

What size range is available?

Butterfly valves cover a wide diameter range and are especially cost-effective in larger sizes where gate valves become heavy and expensive.
