Butterfly valves

LKB LKB is a sanitary automatically or manually operated butterfly valve for use in stainless steel pipe systems. LKB is either remote-controlled by means of an actuator or manually 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 90° 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 DN125 and DN150, which are designed for locking in two intermediate positions, enables adjusting of the valve, so that the flow rate can be regulated. 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. Two actuator sizes, ø85mm and ø133mm, cover all valve sizes. The actuator is available in two versions, LKLA and LKLA-T. The actuator is fitted onto the valve by means of a bracket and screws. The handle for manual operation is fitted onto the valve by means of a cap/block system and a screw. The valve has welding ends as standard, but LKB and LKB-2 can also be supplied with fittings. The most used valves are shown on this page, for more variants e.g. seal material Silicone, FPM, HNBR, please contact your Tetra Pak representative.
