Description
1. USA KNKE Cast Steel Gate Valve Product Overview
The USA KNKE Cast Steel Gate Valve is a high-performance valve crafted from durable cast steel. We manufacture these valves from metal materials, casting them into high-quality components. The materials include grades like WCA, WCB, WCC, and LCB, which are ideal for demanding industrial applications. These valves work well in sectors such as oil, chemical, and power generation. Additionally, the gate valve offers two sealing mechanisms: automatic sealing and forced sealing. High-pressure valves use automatic sealing, while low-pressure valves rely on forced sealing. The valve’s sealing surfaces consist of stainless steel and hard alloys, which ensure excellent durability and provide a reliable seal under harsh conditions.
