Ball Valves Supplier in Pakistan

Ball valves are quarter-turn valves that give quick, reliable, leak-tight shut-off of liquids and gases. A 90° turn of the handle moves the port from fully open to fully closed, which makes them the go-to choice for isolation duty in oil & gas, water treatment, chemical processing, HVAC and general industrial systems. A. Karimjee & Sons supplies ball valves from trusted manufacturers in a full range of sizes, materials and pressure classes, ex-stock in Karachi.

Types We Supply & How to Choose

Ball Valve Types

Selection guide

Full Port: Bore equal to the pipe ID for virtually unrestricted flow and minimal pressure drop — ideal for pigging and high-flow lines.
Reduced Port: Smaller bore that lowers weight and cost where a slight pressure drop is acceptable.
Floating: Ball supported by the seats; economical for smaller sizes and lower pressures.
Trunnion Mounted: Fixed, supported ball for lower operating torque in larger sizes and higher pressure classes.
Flanged: Bolted flange ends for straightforward maintenance on larger lines.
Threaded: Screwed ends for compact, smaller-bore installations.

Frequently Asked Questions

What is the difference between a full port and reduced port ball valve?

A full port valve has a bore equal to the pipe's inside diameter, so flow is unrestricted; a reduced port valve has a smaller bore, which lowers cost and weight but creates a small pressure drop.

When should I choose a trunnion ball valve over a floating one?

Trunnion-mounted valves are preferred in larger sizes and higher pressure classes because the ball is fixed and supported, reducing operating torque and seat wear. Floating valves are economical for smaller, lower-pressure lines.

Do you supply SS316 ball valves?

Yes — ball valves are available in SS304 and SS316 as well as carbon and cast steel. SS316 is recommended for coastal, marine and chemical environments.
