What is an Industrial Ball Valve?

Ball valves are very versatile, they allow, hinder and control the flow of liquids, gases and steam in the piping system by rotating the ball with holes in the valve. The ball is mounted on two seats, connected to the ball using a stem, and the operation of rotating the ball is carried out by a control mechanism. When the orientation of the hole is completely perpendicular to the direction of the fluid in the pipe, no fluid is allowed to pass through the valve. The velocity of the fluid depends on the Angle of rotation of the sphere. Ball valves, like plug valves and butterfly valves, are a kind of right-angle rotary valves. They can be operated manually or with actuators. The simplest operation of the ball valve is to use a wrench or a lever manually turned by the operator. Apply torque to turn the lever arm 90° 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, the valve is closed.

Characteristics of Valve Use

Fast Opening & Closing

The ball valve switch stroke is short, only need to rotate 90 degrees to achieve opening and closing, simple and fast operation, suitable for often open and close conditions
Two-way Flow

Common ball valves are basically two-way seal design, the medium can flow from any direction and provide a reliable seal
Simple Structure

Simple structure is easy to maintain later, greatly reducing the cost of maintenance
Valve Body Straight-through

The flow mode of the ball valve is straight-through, and the resistance received by the medium when passing through the valve body is small, which greatly reduces the wear caused by the medium

About The Key Parts of The Ball Valve

01

Ball

The ball is usually spherical, and the channel is formed in the middle of the ball. The pipeline is controlled by rotating the ball.
02

Body

The spherical body has excellent stress conditions, strong anti-bending and anti-extrusion capabilities, the body is designed with a small wall thickness, light weight, and good overall structural performance.
03

Stem

The stem drives the sphere to rotate through the rotation or push of the operating mechanism to achieve the on-off of the pipeline.
04

Seat

The seat is a positioning device for the ball, usually made of metal, plastic or elastic material. The seat is a groove cut on the spherical surface of the ball. When the ball rotates, it cooperates with the seat to form a seal to prevent medium leakage.
05

Operation

The operation includes a manual operation and automatic operations. The manual operation is usually composed of a handle, gears, etc., and the movement of the ball is controlled by manual rotation or push. In automatic operation, the ball valve is matched with an electric actuator, or a pneumatic actuator.
