GOST Gate Valve

This GOST gate valve from TOT is a type of stainless steel gate valve, which is simple in design and complies with Russian standards. The GOST gate valve consists of a valve body, a valve cover, a valve stem, a valve seat ring, a handwheel and a gate. The valve stem that connects the handwheel and the valve disc is responsible for driving the valve disc to the correct position.

We can provide you with manual, bevel gear transmission and electric stainless steel gate valves. Contact us now to get the most favorable ex-factory price.

Description

When the valve is open, the gate moves in the bonnet to allow full flow. When the gate valve is closed, the gate moves down into the seat, achieving a positive seal.

You can usually use this valve to stop or start flow, because they are not designed for throttling, the valve only operates in the fully open position or the fully closed position. We can also provide you with a two-way gate valve, allowing it to be used in both directions.

Flanged stainless steel gate valves are suitable for ANSIClass150~900, PN2.0~16.0MPa, working temperature -29~425℃ (carbon steel) and -40~500°C (stainless steel) on various pipelines, used to cut off or connect the media in the pipeline.

You can use our stainless steel gate valves for a variety of media fluids such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media and urea.
