Areas of application and industrial sectors

Ball valves can be used in many different applications. However, they are primarily used in industrial processes, in the fields of water supply and water/waste water treatment. In addition to this, GEMÜ plastic ball valves are successfully used in the chemical industry. Alongside valves with straight through body (2/2-way valves), T valves (3/2-way valves) are also available. Accessories, such as seal adjusters and stroke limiters, manual overrides, proximity switches, optical position indicators and electrical position indicators, round off the ball valve portfolio.

Valve type

A spherical rotating body equipped with a flow channel is rotated 90° in a housing. Based on the position of the ball, the valve is then either closed, partially open or open. Gaskets inserted into the housing are used for sealing at the surface of the ball.
