Product Description

American standard forged steel gate valve and flange gate valve belong to the same type of valve, the difference is that its closing part is a ball, and the ball rotates around the center line of the valve body to achieve opening and closing. Gate valves are mainly used to cut off, distribute and change the flow direction of media in pipelines. Two-piece ball valve and three-piece ball valve are a new type of valves widely used in recent years. Generally, these valves should be installed horizontally in pipelines.

The steel American Standard gate valve can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing media and urea and other media. There are manual, bevel gear transmission and electric and so on. Structural features: 1. The fluid resistance is small, and the sealing surface is less brushed and eroded by the medium. 2. The opening and closing of the American standard gate valve is more labor-saving. 3. The flow direction of the medium is not restricted, and the flow is not disturbed and the pressure is not reduced. 4. The shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide
American Standard cast steel gate valve is to rotate the valve love to make the valve open or closed. Gate valve switch lightweight, small size, can be made into a large calibre, reliable sealing, simple structure, easy maintenance, sealing surface and the ball surface is often in a closed state, is not easy to be eroded by the medium, in various industries have been widely used.

Pressure seal bonnets

Pressure seal bonnet gate valves are ideal for high-pressure applications (more than 15 MPa). Pressure seal bonnets have a downward-facing cup inserted into the valve body. When internal fluid pressure increases, the cup is forced outward, improving the seal.

Stem design

The gate is raised and lowered by the spinning of a threaded stem (Figure 2 Labeled B). As discussed, a manual wheel or actuator spins the stem. Depending on the design, it is either considered a rising stem gate valve or a non-rising stem gate valve. So, as you spin the stem, it either raises or stays in place with the spin.

Outside Screw and Yoke , also referred to as rising stems, are fixed to the gate. Therefore, the threads are on the actuation side. So, as the gate is raised or lowered, the stem moves with it up and down. Consequently, they have built-in visual indicators of the state of the valve and are easily lubricated. Since they have moving components, they cannot be used with bevel gears or actuators. Therefore, rising gate valves are suitable for manual actuation.

On the other hand, a non-rising stem is fixed to the actuator and threaded into the gate. An indicator is often threaded onto the stem to show the open or closed state of the valve. Non-rising gate valves are common in underground installations and applications with limited vertical space.
