The ball valve is durable, performs well after many cycles, and is reliable, and can be safely closed even after long periods of non-use. These qualities make them an excellent choice for shut-off applications where they are generally more popular than ga

Good sealing performance improves the reliability of the system. The friction resistance is small, the opening and closing is forceful and flexible. It has a long service life and can be switched repeatedly. High pressure and high temperature resistance,

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

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.

We produce cast iron wafer butterfly valves, with hand lever or worm gear Operator. Our Butterfly Valves are widely used in drinking water system, sewage system, fire-fighting system. Butterfly Valves can produce from size DN40 to DN2400.

The gate valve is a valve that completely restricts the flow of fluid and provides a full-diameter valve without changing the direction. The valve disc is appropriately called a gate here and is moved into the fluid at right angles by a threaded shaft wor

The ball valve is shaped like a bead. But the hole in the center is the same size as the pipe. It has gaskets on both sides of the flow, which can be completely closed. You can install it in any way. No matter which end you choose, one way to turn on the

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.

When the handle wheel is turned clockwise, steam and steam move down through the fluid flow, and the gate is squeezed between the two valve seats, so that no fluid leakage occurs when the valve is completely closed.

Gate valves serve to cut the medium flow in the piping system, widely used in the field of potable water, water supply and drainage, sewage disposal, irrigation, air conditioning, fire protection as well as chemical and energy industry.

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.

These shut-off valves must not be used for on/off service because it is impossible to achieve a tight seal. The disc in the valve can be completely removed from the flow path, or the flow path can be completely closed.

Ball valves are valued for their long service life and excellent performance even after many years of use. Inside the ball valve, the ball is usually drilled from one end to the other, and is usually made of brass, chrome brass, or stainless steel. A leve

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 gate valve cannot be opened and closed quickly. To fully open or close the wheel or gearbox actuator, the shaft should be rotated to the number of fully open revolutions. The number of full-open revolutions is equal to the pitch.
