The basic principle of this valve is based on the floating ball sealing against the downstream seat using the differential pressure as the sealing force. Both seats are fixed (stationary) whilst the ball has pre-determined “floating space”
The ball valve has a three-part-body design. As a control valve usually has a reduced central bore, this allows pipe size end connections at either end of the valve.
Actuator connection is done by yoke and adaptor and the valve can be operated by quarter turn pneumatic, electric or hydraulic actuators
