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.

A three-way ball valve is a three-way valve that allows fluid to flow to an alternative path to the hydraulic system. It allows fluid to enter and exit the valve through more than one port.

The stop valve opens and closes the valve with the help of a plug-shaped disc, which is tightly fixed in the valve.

The main difference between these two types is the way they are closed. The stop valve uses a plug (stem) that closes against the flow, while the ball valve has a gate (ball) that can close the entire flow. The stop valve is suitable for adjusting the flo

This is the connection from the actuator to the valve, which provides the driving force. The stem of the actuator control valve can be smooth, and the stem of the manual control valve can be threaded.

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.

Concentric design wafer butterfly valve, with no back structure, rubber welded valve body, replaceable elastic seat, streamlined disc, integrated stem

Ball valves and plug valves are very similar in basic functions and applications. Both are control valves used to provide tight shutoff in different types of piping units. They also work on the same basic principle, that is, using a porous disk to start o

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 is externally threaded and yoke type full bore, with elastic wedge and rising stem.

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

The pressure-sealed gate valve is designed in accordance with API 600, suitable for high temperature and high pressure working conditions, and is widely used in nuclear power plants and thermal power plants. Compared with bolted bonnet joint valves, they

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.

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.
