Our ball valve is a quarter turn shut-off valve that controls the flow of fluids by a rotary ball. The spherical rotary ball consists of a straight bore through it. The pipe is in the open position when the bore is aligned in the same direction as the flow, allowing the fluid to pass through it. When the bore is rotated 90 degree from the flow path, the valve is closed, and the flow is blocked. Ball valves are used in residential and commercial application for its reliable sealing properties and long service life. The image below is an example of a sectional view of a ball valve.

* S&W Floating Ball Valves

1) Reliable Seat Seal : Double-beveled sealing ring in order to reduce the friction between the ball and the sealing ring to achieve lower operation torque. 

2) Fire safety Design 

PTFE seats

3) Blow-out Proof Stem: An internal entry anti-blow out stem maintains maximum operating safely at high operating pressure.

4) Anti -Static Design: spring-loaded devices which maintain contact between ball and stem, and stem and body to ensure electrical continuity

5)Live Loaded Gland Flange: Live Loading is designed to provide gland load retention, compensating for expected in-service consolidation of packing. 

6) Locking Device

* Trunnion mounted Ball valves 

S&W Trunnion Ball valves are designed in accordance with API 6D for classes ASME class 150,300,600,900,1500 and 200.

1) Body Joint Construction 

2) Stem Design/Anti blowout

3)Anti-static Device

4)Emergency sealant injection 

5) Fire safety 

Fire Service: Designated by manufacturer as being applicable for use in fire service 

Metal Seated: Valves with metal seats are desgined for severe applications such as high pressure and temperature. Seats can be made of various materials such as carbon & Stainless steel to withstand the demanding application.

Severe Service Rated: The valve is designated by manufacturer as being suitable for sever service where there is continuing operational 

Valve size: Valve size is the designated size of the valve by S&W 

Pressure Rating: Maximum safe pressure value for which valve is rated.
