The main difference between ball valves and globe valves is the way they close. A ball valve has a stem and a ball, which rotate horizontally and are usually called "rotary" valves. The globe valve has a stem and a plug, which stroke linearly, a

For non-vertical stem type valves, if the valve is opened, the stem will not move upward. The stem is screwed into the dish. When the handwheel on the valve stem rotates, the disc moves up or down along the valve stem on the thread, while the valve stem r

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.

Ball valves are widely used in petroleum and natural gas, chemical and petrochemical, food industry, water supply, water treatment, building construction, light industry, power generation, pharmaceuticals, biotechnology, laboratory equipment, marine and o

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 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

Our gate valves are cheap, but durable and reliable. We believe that our deep research and development and rich production experience are important reasons why we are trustworthy.

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

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

The structure of the wafer butterfly valve is formed by the central disc rotating 90 degrees in the valve body. Using the drive type, the flow of fluid can be stopped, adjusted or started. In the wafer connection, the valve is installed between pipe flang

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

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.

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.

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