304 Pulp Valves Supplier, check sizes of ASTM A351 CF8M 316 Slurry knife gate valves

Knife Gate Valve is a type of valve that has a gate. The gate is embedded in the valve body and is controlled by a threaded stem. The stem has a handle on top and is operated by the handle. The knife gate valve manufacturers produce them in various material grades and standards. The gate valves can come in different types for different applications requirements. Sometimes the fluid is too thick to be block by an ordinary gate. This is where sharp ended knife gates are used. These are good in blocking high viscosity fluids by cutting through them and blocking the fluid flow. The knife gate valve manufacturers in india produce the valves for pulp and paper, power plant, wastewater treatment plants, chemical plants, food and beverages, mining industries and many other industries.

Biggest Supplier of Knife Gate Valve, Refer SS Wafer and lug type knife gate valve Dimensions

The sizes range with the knife gate valve specification. There are sizes ranging from DN50 through DN1200 and larger diameter valves can be made upon request. The standard sizes are used mostly in the industries. The working pressures of the valves differ as well. There are different pressures and diameter correlations. The DN50 through DN250 flanges can handle pressures of 10 bars, valves up to DN400 are made for 6 bar pressure and so on. The knife gate valve dimensions such as the body width, flange size, face to face fitting size, the inflow and outflow diameters vary with the valve type and the application requirements.
