BRASS AND SS BALL VALVE
[CODE NO.4222]
Ball valves are used to shut-off pressurised media in pipes or hoses
A ball valve is a rotational motion valve that uses a ball-shaped disk to stop or start fluid flow.
The ball performs the same function as the disk in the globe valve. When the valve handle is turned to open the valve, the ball rotates to a point where the hole through the ball is in line with the valve body inlet and outlet. When the valve is shut, the ball is rotated so that the hole is perpendicular to the flow openings of the valve body and the flow is stopped.
Most ball valve actuators are of the quick-acting type, which require a 90??turn of the valve handle to operate the valve. Other ball valve actuators are planetary gear-operated. This type of gearing allows the use of a relatively small handwheel and operating force to operate a fairly.
Some ball valves have been developed with a spherical surface coated plug that is off to one side in the open position and rotates into the flow passage until it blocks the flowpath completely.
Seating is accomplished by the eccentric movement of the plug. The valve requires no lubrication and can be used for throttling service.
The ball valve is a quarter-turn valve suitable for clean gas, compressed air, and liquid service. They also can be used for slurry service, but provisions for prevention of crud buildup must be made. The use of soft-seat materials such as nylon, delrin, synthetic rubbers, and fluorinated polymers imparts excellent sealing ability.
With fluorinated polymer seats, ball valves can be used for service temperatures ranging from 450 to 500 F ( 270 to 260 C); with graphite seats, service temperatures to 1000 F (538 C) or even higher are possible. Also, with metal backing seats, the valves can be used in fire-safe services. Ball valves are similar to plug valves in operation. They are nonbinding and provide leak-tight closure. The valves exhibit negligible resistance to flow because of their smooth body and port.
