GATE VALVES

As a trustworthy gate valve company, gate valve factory in China, MstnLand provides high performance gate valve products, mainly include bolted bonnet wedge gate valves and pressure seal bonnet gate valves China, which are widely used in gas, petrochemical, oil, offshore, power station and refining industries.



The gate in the industrial gate valve is for opening and closing purposes. Its motion direction is perpendicular to the direction of fluids. The gate valve can only be fully opened and fully closed, and can not be used for flow regulation. Therefore, when the valve is fully open, the flow channel is straight-through and the pressure loss difference is minimum. So gate valves can be used in many conditions.



Types of Gate Valves Based on Material



When selecting different types of gate valves, you should pay more attention to the valve body material which should be determined by the actual working conditions such as temperature, pressure medium. We are a professional Chinese gate valve manufacturer who supplies gate valves made of stainless steel, wcb, carbon steel, forged, cryogenic, etc. And based on the body materials, you can find different types of gate valves are for sale now in Mstnland.

Gate Valves Working Principle

The opening and closing part of gate valve is a flashboard. Its direction of motion is perpendicular to the direction of fluid. A gate valve is usually used to cut off the medium. The entire flow channel is a straight-through passage when gate valve is fully open, and the pressure loss of the 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 and wedge 2-flashboard gate valve. Gate valve is usually used under working conditions 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. Various materials may be selected for transportation of water, steam, oil, natural gas, nitric acid, acetic acid, oxidant and urea.
