As an experienced Gate Valve Supplier, our gate valves are produced strictly in accordance with international standards, suitable for harsh environments such as high temperature and high pressure, corrosive media, and widely used in industries such as oil, natural gas, chemicals, and power plants.
Are you looking for a Gate Valve with high cost performance, on-time delivery, and support for customization? Welcome to consult now!
Grooved Gate Valve is an opening and closing component, the gate plate’s movement direction is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.
Different types of gate valves to meet your needs
From the outside, most water gate valves look somewhat similar, however, the internal design is different. Most flanged gate valve consist of a valve body and a bonnet, which contains a closing element, called a disc or gate. The closing element is connected to a stem that passes through the bonnet and is ultimately connected to a handwheel or other actuator to operate the stem. The pressure around the stem is limited by the packing that is compressed into a packing area or chamber.
The movement of the cast iron gate valve disc on the stem determines whether the stem rises when the disc is opened or screwed in, and this reaction also defines the two main stem/disc types of gate valves: rising stem or non-rising stem (NRS gate valve). Rising stems are the most popular stem/disc design type in the industrial market, while non-rising stems are more popular in the waterworks and pipeline industries. Of course, some marine applications where gate valves are still used and space is limited also use the NRS type.
The most common stem/bonnet design in industrial valves is the external thread and yoke (OS&Y gate valve). The OSY design is preferred for corrosive environments because the threads are outside the fluid sealing area. It also differs from other designs in that the handwheel is attached to a bushing on top of the yoke, rather than to the stem itself, so the handwheel does not rise when the flanged gate valve is opened.
We also supply all sizes of gate valves, including high-quality 6 in gate valves, ensuring reliable performance for your industrial needs.
