SW Gate Valve


Description of Sw Gate Valve:

ZECO is a well-known SW gate valve manufacturer and a long-term supplier to global industrial companies and oil stockists. When the ZECO SW gate valve is fully opened, the sealing surface of the gate has little contact with the medium and is less corroded by the medium of pipeline, which can ensure long-term and efficient sealing performance. Forged gate valves are usually used when the user needs the line to maintain a minimum pressure loss.When the gate valve is fully opened, it has no contact with the medium in the pipeline, which is equivalent to a section of pipeline, and produces a very low pressure loss. This structure also makes it easier to clean the pipeline. The gate valve is also a multi-turn valve.
