Product details

Gate valves are the most common valves which are used for opening and closing. We mainly produces Gate valves according to the standard of API 600. We call them API 600 Gate valves. According to different design standards, DIN Gate valves are also avaiable

.

The body of Gate valves may be made of metals. Such as: Forged Steel Gate valves, Stainless Steel Gate valves, Alloy Gate valves, Bronze Gate valves, Cast steel Gate valves and Carbon Steel Gate valves, ect. Among them, Forged Steel Gate valves are widely used especially as the shut-off devices when size is more than 50mm.Our products are Forged Steel Gate valves according to the standard of API 602. And Stainless Steel Gate valves according to the standard of API 603, we call them API 602 Forged Steel Gate valves and API 603 Stainless Steel Gate valves.The body can also be made of non-metal materials. For example, Ceramic Gate valves, which have good performance of abrasion and hardness.


Some other Gate valves are made of special materials, such as Hastelloy Gate valves、Special Steel Gate valves and Special Alloy Gate valves.Transmitting and processing of media that are heavily corrosive, Duplex Stainless Steel Gate valves or Super Stainless Steel Gate valves are usually selected to mitigate the problems for they can work well in the area with corrosive surroundings.


Owning a gate/ wedge makes Gate valves such different and characteristic. By lifting the gate/ wedge, the Gate vales allow the fluid to go through the path successfully.There are different kinds of wedges/gates. A Wedge Gate valve can be equipped with single gate disc, double gate disc and resilient gate disc, ect,. Generally speaking, the Gate valves are designed to be fully open or closed, thus having no function of throttling. For extremely thick fluid, Knife Gate valves are commonly used to cut through the fluid.


Gate valves have different connection types, which resulting in different kinds of Gate valves.They are Flanged Gate valves, Screwed Gate valves, Butt Weld Gate valves and Socket Weld Gate valves. When connected with the pipeline, Flanged Gate valves have flange ends which are drilled according to flange dimensional standards compatible with pipeline.
