Ball valve is a form of right-angle rotary valve, which uses a hollow, perforated and rotating ball to control it. It is open when the hole of the ball is aligned with the hole of the ball, and it is closed when it is rotated 90 degrees by the valve handl

The sealing ring adopts seatback type, mortise type or directly vulcanized on the valve body. The sealing surface of the valve seat flange adopts an O-ring to cooperate with the pipe flange cone, and the sealing effect is good. It is easy to disassemble a

Push-in joints do not require solder, glue, unions or tools. Corrosion resistant to extend service life, designed for drinking water distribution and circulating heating applications.

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

If the flow, volume and pressure can be adjusted frequently, the stop valve can be used as a control valve. The design of the shut-off valve makes it very suitable for flow regulation and start and stop flow.

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.

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 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

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.

The stop valve is a linear motion valve, which can be used to start and stop and adjust the fluid flow. The stop valve is mainly used for throttling service and automatic control.

The ball valve is designed to contain a ball in the valve. There is a hole in the middle of the sphere, and when the hole is aligned with the two ends of the valve, flow will occur. When the valve is closed by rotating the ball 90 degrees, the hole is per

The manual gate valve is operated by a simple handwheel to raise the valve stem and gate. When closed, the gate rests on a seat ring, both of which are specially treated to provide a reliable closure.

The most common causes of gate valve failure are wear and corrosion. Over time, gate valves tend to wear out. Corrosion can cause the disc to get stuck in the open or closed position. When the handle is stressed, the valve stem leading from the handle to

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.

In the 19th century, due to the increasing use of gate valves in industrial operations, their intensive development moved forward rapidly. Over time, the materials involved in manufacturing have been improved and modified to suit different applications.
