LKB Automatic or Manual Butterfly Valve Application
LKB is a sanitary automatically or manually operated butterfly valve for use in stainless steel pipe systems. Working principle LKB is either remote-controlled by means of an actuator or anually operated by means of a handle. The actuator is made in three standard versions, normally closed (NC), normally open (NO) and air/air activated (A/A). The actuator is designed so that an axial movement of a piston is transformed into a 900 rotation of a shaft. The torque of the actuator is increased when the valve disc contacts the seal ring of the butterfly valve. The handle for manual operation mechanically locks the valve in its open or closed position. The handles for the valve sizes NW125 and NW150, which are designed for locking in two intermediate positions, enables adjusting of the valve, so that the flow rate can be regulated. Standard design LKB is available in three versions, LKB for ISO tubes, LKB-2 for DIN tubes and LKB-F for flange connection. The valve consists of two valve body halves, valve disc, bushes for the disc stem and seal ring. LKB-F also consists of two flanges and two flange seal rings. The valve is assembled by means of screws and nuts
