COMBINING WITH AN ACTUATOR UNIT The ball segment valve is first and foremost a control valve offering excellent tightness in the closed position. The properties of this valve make it useful for most applications. Combined with Somas pneumatic actuators and positioners the result is a flexible unit with a wide control range. Good tightness up to class V for metal seats and class VI for soft-seal seats. The one-piece design of the ball segment and shaft results in backlash-free operation and accurate control The valve segment comes with dual bearings which results in high durability and low torque requirement The valve seat can be replaced from the outside without the need to disassemble the valve, this makes the valve service friendly Valve body with a centrally mounted ball segment
