Product Description

A ball valve is a flow control device which uses a hollow, perforated, and pivoting ball to control fluid flowing through it. It is open when the hole through the middle of the ball is in line with the flow inlet, and closed when it is pivoted 90 degrees by the valve handle, blocking the flow.

They can be operated manually or by using an actuator. The simplest operation of a ball valve is through the use of a wrench or a lever manually turned by an operator. Torque is applied to rotate the lever arm by 900 by either clockwise or counterclockwise to open or close the valve. If the lever arm is parallel to the pipe, it indicates that the valve is open. If the lever arm is perpendicular to the pipe, it indicates that the valve is closed.

Ball Valves are used for flow and pressure control and shut off for corrosive fluids, slurries, normal liquid, and gases. They are used in the oil and natural gas industry, but also find a place in many manufacturing sectors, chemical storage, and even residential uses.


Ball valves are simple to operate and maintain
Quick to open
Can be operated manually or by actuation
Causes little turbulence when fully open
Has a low pressure drop and can handle relatively high flow capacities


Ball valve is a shut-off valve that allows, obstructs, and controls the flow of liquids, gases, and vapors in a piping system by rotating the ball having a bore inside the valve. The ball is mounted against two seats and has a shaft that connects it to the operating and control mechanism that rotates the ball. When the cross-section of the bore is perpendicular to the area of the flow, the fluid is not permitted to pass through the valve. The fluid flows through from the valve, and the fluid flow rate depends on the area of the bore exposed to the flow.



The primary components of a gate valve include the body, bonnet, ball, stem, and seat.
