Ball Valve

Category

Quarter-turn ball valves for reliable isolation with full-bore, reduced-bore and multiple seating options.


Ball valves are a practical choice when a piping system needs quick shutoff without a complicated operating sequence. Their quarter-turn movement keeps operation simple, while the bore through the ball provides a direct flow path when the valve is open. SVR Global, a Ball Valve Manufacturer in USA, supplies configurations for new installations, plant upgrades and replacement work where dependable isolation and repeatable operation are required.

What is a Ball Valve?

A ball valve is a rotary valve that uses a spherical closure element with a hole through its centre. When the bore is aligned with the pipeline, fluid passes through the valve. Turning the ball through 90 degrees places the solid part of the ball across the flow path and stops the flow.

Ball valves are mainly used for on/off isolation. Their performance can vary considerably depending on how the ball is supported, the type of seat used, the body construction and whether the valve has a full-bore or reduced-bore passage. 

What Makes Ball Valve Designs Different?

Ball Support

The way the ball is supported influences seat loading, operating torque and suitability for different pressure conditions.

Seat Design

Soft and metal seating arrangements are selected according to shutoff requirement, temperature and service conditions.

Body Construction

Cast, forged, bolted and welded bodies provide different approaches to strength, maintenance access and external sealing.

Bore Design

Full-bore and reduced-bore configurations allow the flow passage to be matched to pressure-drop and installation requirements.

Ball Valve Features

• Quarter-turn operation for quick opening and closing

• Full-bore and reduced-bore flow options

• Soft-seated and metal-seated configurations

• Anti-blowout stem and anti-static design options

• Fire-safe and low-emission configurations

• Manual, gear and automated operating options

Seat, body and operating arrangement can be selected to suit the service conditions without changing the basic quarter-turn operating principle.
