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.

Ball valves are more effective in forming tight seals and have higher reliability and life than gate valves, but they are more expensive. They are often used to shut down and control applications. Because the ball valve can be opened and closed instantane

Gate valves are widely used in pipelines to transport media. Gate valves can be divided into wedge gate valves, flat gate valves, parallel double gate valves according to the form of valve seats. The product can have a longer service life. It can be insta

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

Industrial applications such as power generation, mining and chemical industries use gate valve. What makes it useful is that the design limits flow barriers. In addition, there is minimal pressure drop. This kind of valve can also be used when the pressu

You can expect the service life of the shut-off valve to be approximately 10 to 25 years, with an average of 20 years. However, if they are not "exercise" once a year or two years, then when you really need to close the valve for a pipeline emer

The ball valve is designed to contain a ball in the valve. The ball valve is a form of quarter-turn valve that uses a hollow, perforated and rotating ball (called a "floating ball") to control the flow through it. It is open when the hole of the

The closing function of gate valves is very good. They provide laminar flow with minimal pressure loss.

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.

Gate valves Gate valves are called rising valves or non-rising valves. Around the non-vertical stem gate valve, the stem is screwed into the gate around the lower end surface. Because the handwheel around the valve stem rotates, the gate will move the val

Resilient seat gate valves are used for purification and pumping of sewage, fire fighting systems, irrigation, industrial pipelines, etc. It has minimal head loss, 100% water tightness and full bore.

The operation of the gate valve is to perform a clockwise closing (CTC) or clockwise opening (CTO) rotary movement of the valve stem. When the valve stem is operated, the gate moves up or down on the threaded part of the valve stem.

Gate valves can be divided into two main types: parallel and wedge. The parallel gate valve uses a flat gate between two parallel valve seats. The popular type is a knife gate valve with sharp edges on the bottom of the gate.

The gate valve is not suitable for throttling volume. Due to the design of the valve, a partially opened gate of the fluid flow will cause serious damage to the valve, so flow control is difficult. Unless specifically authorized by the manufacturer, the g

In the shut-off valve, the flow of water is controlled by a movable mandrel, and the flow of water is restricted by lowering the mandrel to a fixed valve seat.
