Do not use the valve as a crowbar to open the flange, as this may cause damage to the flange area and/or damage to the O-ring seal.

Cast iron gate valves are used in commercial and industrial applications. Its typical services include: hot and cold water, HVAC, steam, gas and other general utility services.

The three-way ball valve is made of stainless steel and can withstand a working pressure of 1000 PSI. The available ports are L-Port or T-Port. The ball valve is connected at the threaded end: BSPP or NPT.

Compared with ball valves, gate valves require multiple turns to fully open. The valve is not suitable for throttling or control, because partial opening will cause damage to the gate and wear of the valve seat. In addition, some valve closures can cause

The valve seat of the gate valve is either provided integrally with the valve body or adopts a seat ring structure. The valve seat provided by the valve seat ring structure can be screwed into place or pressed into place and sealed and welded to the valve

The valve seat is responsible for the movement of the valve gate. It can also help to further seal the flowing medium. For gate valves, there are two valve seats according to the type of gate. Take the wedge valve as an example, the valve seats on both si

The pipeline gate valve is designed to meet the long-distance transportation service of crude oil and natural gas. It is designed in accordance with API 6D and has DBB function, so the valve can provide two-way switching services. Our straight-through con

This kind of gate valve is more flexible, because its gate can move up or down, there is no obstacle to the flow of fluid or gas, thus ensuring less friction.

The gate valve can provide different discs or wedges. The range of the gate valve is usually determined by the type of wedge used.

Our company can also provide customized valve services according to your requirements. Feel free to contact us for more information or to request a complete product category.

The valve body and bonnet are made of castings and are connected by flange joints. The seat surface of the valve seat and the wedges conform to the API 600 standard. The seat ring is welded into the valve body.

Gate valves and globe valves are the two most common types of valves in industrial applications. Both have made great contributions to any industrial service. They may look similar, but the functions of these valves are different.

We test every valve during the production process, and carry out quality control in all processes such as forging, processing, and assembly to ensure quality.

The gate valve is composed of three main parts: the valve body, the valve cover and the valve trim. The body is generally connected with other equipment through flange, thread or welding connection. The engine cover containing the moving parts is usually

The working principle of the stop valve is the vertical movement of the valve disc away from the valve seat. So when the valve is closed, it will cause the space between the disc and the seat ring to close. This is why these valves are used to start, stop
