Flat Gate Valve

About the flat gate valve, the two sealing surfaces are parallel to each other and vertical to the channel center. The disc is of flat plate shape. The elastic and floatable seat can always be kept close to the disc during the opening and closing process. The flat gate valve is mainly used for long transportation pipelines of crude oil, product oil, natural gas, etc. The flat gate valve with diversion hole is suitable for pipelines that require pigging, and the flat gate valve without diversion hole is suitable for pipelines that do not require pigging.

Flat gate valve is a sliding valve with parallel gate valve. The closure is a single ram. The valve can be divided into two parts: the flat gate valve with the diversion hole and the flat gate valve without the diversion hole. It is applicable to gas pipeline, crude oil pipeline, etc.

The plate gate valves can be designed and manufactured with single disc and double discs structure, the products conform to the latest API, GB, ISO and other related standards, because of its unique double discs structure, it can achieve excellent bi-directional sealing performance under both high and low pressure. The greater the torque, the tighter the seal. During the switching process, the sealing face of the discs and the seat ring are separated from each other, thus reducing the wear and tear of the sealing surface and prolonging the service life of the valves. It is widely used in the pipeline for oil and natural gas. The flat gate valve has a pilot hole which allows the cleaning balls to pass through. The flat gate valves are designed to minimize pressure drop and prevent impurities such as mud from entering the valve chamber.

Medium: The valve is suitable for several media including water, steam, oil, gas, petrol products, nitric acid, acetic acid, etc.

Our company provides high performance gate valve products, including Wedge gate valve, Pressure seal gate valve, Knife gate valve, Flat gate valve and Bellow seal gate valve.

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 used under some 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.
