Flowjet Valves : Industrial Valves Manufacutrer

Floating Ball Valve

Flowjet Offer a whole range of Ball valves in a variety of sizes, pressure ratings and materials, in wafer style, or screwed, welded or flanged connections.

A ball valve has a quarter turn spindle connected to a ball inside the valve. The ball has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked.The handle position lets you see the valve’s position. On a floating ball type, the upstream pressure the ball against the seat, giving a tight shut off. On a trunnion mounted type, the ball is fixed; seat sealing action is achieved by the thrust of springs acting on the seat rings, as the pressure increases the fluid pressure pushes the seat rings against the ball.

Ball Valves are Strong enough & Usually work to achieve the perfect shutoff even after years of No use. Therefore Ball Valves are Perfect Choice for Shutoff Application & are often preferred to globe & Gate valve for this purpose, especially in smaller size.

However, standard ball valves do not offer the fine control that may be necessary in throttling applications, but V ported ball variations are available for control purposes. The unrestricted bore in full bore ball valves make them ideal for hot tapping andpigging.

Being a quarter turn from fully open to fully closed, and having a relatively low operating torque, ball valves can be readily actuated for remote operation.
