Stainless Steel knife gate valve is a type of valve that has a knife like structure inside the body that is seated on the pipeline and is driven by a threaded stem. Suraj Metal Corporationis a leading manufacturer and supplier of the Stainless Steel Pulp Valve and other types in different sizes, scales and dimensions. The size ranges of the valves vary for resilient and metal seated pneumatic knife valve from 2 inches to 54 inches.
The pressure ratings range from 150psi for smaller valves and 100psi for larger valves. There are different types such as the Slurry knife gate valves that are used for slurry removal. These valves cannot be used to control the flow. These can only be used to completely open or close a pipeline. As the Wafer and lug type knife gate valve is designed to descend and ascend slowly, it minimizes the hammer effect by the liquid inside the pipe. If the valves are used to control the flow by opening it half way through, the resilient seated knife gate valve can cause cavity and be subject to water hammer effect. As a leading supplier, we produce and supply the different types such as the metal seated knife gate valve and others. Please feel free to contact us for more detailed information and pricing of the different types of valves such as the bonneted knife gate valve.
