Description
WESDOM gate valves are reliable, offering a tight shut-off and low pressure drop. The design covers a wide range of requirements to meet any customer need from general to severe service conditions. WESDOM gate valves are in compliance with the latest edition of API600 , API6D , ASME B16.34,etc.
Gate valve is one of the most widely used valves in various fluid transportation projects.In traditional gate valves, there are common phenomena such as fluid leakage and serious internal corrosion. Common soft-seal gate valves and stems on the market The shaft seal is easy to leak, and it is impossible to replace the seal ring under the condition of constant water and any opening.
