The valve body portion of the manual high platform ball valve is designed with a higher platform for easy installation and removal of the manual handling handle. Its working principle is to drive the rotation of the valve stem and the ball by rotating the handle or the hand wheel, so as to control the flow and cut-off of the medium. When the handle or handwheel rotates, the stem moves with it, which in turn drives the ball to rotate in the seat. When the sphere channel is aligned with the pipeline flow channel, the medium can flow; When the sphere channel is staggered with the pipeline channel, the medium is cut off.

Structural characteristics

High platform design: Easy to install and remove manual handling handles, improving valve maintainability.

Ball and seat: The ball is usually made of a corrosion-resistant material, such as stainless steel, and the seat is closely fitted to the ball to ensure tightness.

Valve stem and handle: The valve stem is fixed on the ball and connected with the handle, and the rotation of the valve stem and the ball can be driven by rotating the handle.

Sealing structure: A sealing ring is usually installed between the ball and the seat to enhance sealing and prevent media leakage.
