Specification Sheet
How the LKB-F Valve Works
The LKB-F Butterfly Valve can be operated with a Pneumatic Actuator, or a handle. There are three versions: normally closed (NC); normally open (NO); and air/air activated (A/A).
For pneumatic operation, an actuator converts axial piston motion into a 90° rotation of the shaft. The torque increases as the Valve disc contacts with the seal ring of the Butterfly Valve, to secure proper closing of the Valve seat.
For manual operation, a handle locks the Valve in open or closed position. Two-position, four-position, regulating 90°-position, and multi-position handles are available. Indication Units can be mounted on manual Valves for feedback on their position.
