What's gate valves & features

Opening and closing part of gate valve is flashboard. Its direction of motion is perpendicular to the direction of fluid. The valve is usually used to cut-off medium. The entire flow channel is a straight-through passage when the valve is fully-open, and the pressure loss of medium running is minimum. Gate valve is usually divided into several types by seal part mode, such as: wedge gate valve, plate gate valve, parallel 2-flashboard gate valve, wedge 2-flashboard gate valve. Gate valve is usually for working condition in which the valve is not opened or closed frequently, and supports flashboard fully open or fully closed. It's not suitable for adjustment or throttling. Different materials may be selected for transportation of water, steam, oil, natural gas, nitric acid, acetic acid, oxidant and urea.

Our cast steel gate valves are widely used in the industries of oil, chemical, medicine-made, fertilizer, electrical power, etc. as on/off control valves for passing or cutting off the medium. The gate is designed as a wedge flexible gate of easy seal and wearing compensation, seal surface is overlaid with wearing resistant hardened alloy; the seat seal surface overlaid with wearing resistant hardened alloy to be matched with gate seal surface; the stem is specially treated to ensure its strength, rigidity, corrosion resistance and abrasion resistance. Our gate valve is with reliable seal, safe use and easy 
operation. Valves are available in a complete range of body/bonnet materials and trims, which are used for the medium of water, steam, oil product, nitric acid, acetic acid, etc.
