The block-type ball cock K 72302 is a robust flow-control component used in the cylinder lubrication system of the Sulzer ZV40/48 engine, designed to regulate and isolate the supply of lubricating oil to individual cylinders. Featuring a compact block construction and a precision-machined ball valve mechanism, it ensures reliable shut-off and smooth flow adjustment under pressure. Engineered to withstand oil exposure, vibration, and thermal variations, this valve provides durable and leak-free operation over long service intervals. By enabling precise control of lubrication flow, the K 72302 ball cock plays a key role in reducing wear, optimizing lubrication efficiency, and ensuring long-term engine reliability.
