The basic principle of this valve is based on the floating ball sealing against the downstream seat using the differential pressure as sealing force. Both seats are fixed (stationary) while the ball has a predetermined “float-space”.
The ceramic components are embedded into a metal housing which absorbs the physical torque and vibration resulting from the pipeline.
The quarter turn motion of the ball (0-90) yields in a specific valve opening. The geometrical shape of the ball allows for different control characteristics in function of process requirements.
The ball valve has a three-part-body design. This allows direct connection to existing pipelines while optimising flow and control characteristics (larger opening angles thanks to a reduced central bore).
Actuator connection is done by yoke and adapter. All kinds of quarter turn pneumatic, hydraulic and electric actuators can be used. Manual operation with hand lever is also available. Standard connection is according to the DIN / ISO 5211, special connections are possible.
