1. Corrosion Resistance. The sealing surface of the valve is easy to corrode because of the medium. If the surface corrodes, its sealing performance cannot be guaranteed. Therefore, the material used for the sealing surface must be corrosion resistant. The corrosion...

Check valves can be divided into swing check valves and lift check valves. Swing check valves can only be installed on horizontal pipes, while lift check valves can be installed on both horizontal and vertical pipes. First, look at the consequences of a pump without a check valve: The water flow in...

Check valve for coal chemical industry According to the structure of the check valve, it can be divided into three types: lift check valve, swing check valve and butterfly check valve. Lift check valve can be divided into vertical type and horizontal type. Swing check valve is divided into three types:...

Except that some general-purpose valves can be used in some coal chemical industry conditions,  which valves are special valves for coal chemical industry? Metal hard-seal wear-resistant ball valve, including: lock hopper valve, slag lock valve, ash lock valve, air release valve, balance valve....

The purpose of a steel gate valve is to control the flow of liquid. A steel gate valve is installed on many occasions, the most common is installed on an external spigot. We turn the knob to open a valve which allows water to flow through the hose, and close...

Check valves are different from other types of valves in function, and they pass fluid in solely one direction. This sort of function is essential for a variety of safety applications, as well as for preventing overflow. Operating on a two-port system, check valves have an opening where...

What are the characteristics and applications of straight-through single-seat control valves? (1) The discharge flow is small, the sealing performance of this kind of valve can be assured since it has only one valve core. The standard discharge flow is 0.01% KV and can be further designed as a shut-off...

As indispensable equipment in industrial production, valves may encounter many problems from selection, use to maintenance. Here are some common questions and answers. What are the three main factors that should be considered when choosing a valve? (1) The output of the actuator is greater than the...

The unique characteristics of the ball valve determine the use of it is relatively wide, usually in the two-position adjustment. With their good sealing performance, quick opening and closing action  (1/4 turn open and close), ball valves are recommended for piping systems with high pressure cutoff...

A ball valve is mainly used in the pipeline to cut, distribute the flow and change the flow direction of the medium. It can be closed tightly by only a small torque and being rotated 90 degrees. The ball valve is most suitable for use as a switch or shut-off valve. Ball valves were introduced in the...
