The LKB butterfly valve is controlled manually by means of a handle. The handle mechanically locks the valve in its open or closed position. For the LKB and LKB-2, the handles for the valve sizes DN125 and DN150 enable valve adjusment and can be locked in two intermediate positions to regulate the flow rate.
The valve body is made of two separate halves assembled by a clamp. A specially designed rubber seal is fixed between the two halves and a profiled disc closes against the seal. The LKB-2 valve has a handle in stainless steel, which by the use of the standard locking cover ensures that the valve can be securely locked in the closed position.
LKB-2 is a sanitary, manually operated butterfly valve which is used as a shut-off valve when needing a valve easily dismantled for cleaning and inspection, eg. on farm milk tanks.
