Valves are devices used to regulate fluid flow, pressure, and flow direction. Regulated fluid can be a liquid, a gas, a gas-liquid mixture, or a solid-liquid combination. The valves normally consist of the body, cover, valve seat, opening and closing components, driving mechanism, seals, and connectors. The control function of the valve is obtained by means of a driving mechanism …

The pneumatic ball valve is a pneumatic actuator-equipped ball valve. With the fastest operating speed of 0.05 seconds per second, pneumatic actuators operate very rapidly, so they are typically often called pneumatic fast plugging ball valves. In order to complete in-site control and remote centralized control, pneumatic actuated ball valves are normally fitted with different accessories, such as solenoid valves, …

The globe valve and the gate valve have a certain similarity in appearance, and as both valves have the role of cutting off in the pipeline, so the people always ask what the difference is between the globe valve and the gate valve? 1. The variation in the working principles of globe valve vs gate valve. Whenever the globe valve …

In normal conditions, industrial valves are not subjected to a strength test while in operation, but after maintenance, the corrosion-damaged valve body and cover may be subjected to a strength test. In the case of safety valves, steady pressure, return pressure and other checks should meet with the standards and associated regulations.  The valve strength test and the valve sealing …

Industrial Valves have some problems during operation, e.g. the valve is not closed tightly. What am I supposed to do? In normal circumstances, if the valve is not completely closed, first check to see if the valve is closed in place. If it has been closed in place, and the leakage persists, then check the sealing surface. If it is …

Regulating valves are often referred to as control valves. It accepts the control signal output from the adjustment control unit in the area of industrial automation process control and uses power operation to alter the final control element of process parameters such as medium flow, pressure, temperature, and liquid level. It normally consists of a drive actuator and a valve. …

Valve corrosion is commonly viewed as damage to the metal material of the valve under the effect of a chemical or electrochemical environment. Since the “corrosion” occurs in the spontaneous reaction between the metal and the surrounding environment, the prevention of corrosion focuses on how to separate the metal from the surrounding environment or use more non-metallic synthetic materials. Here …

Flange Ball Valve is a control component in the piping flow system used to cut off and distribute the direction of the medium flowing in the pipeline. In operation, a rotation of 90 degrees with a small torque is sufficient to close the valve tightly. Flanged ball valves are made of metals such as carbon steel, stainless steel or brass, …

Valves are the control component in a piping flow system. The main functions include: – Isolating equipment from the piping. – Regulating the flow rate. – Preventing backflow of liquid. – Regulate discharge pressure in the piping system.   Valves can be used to control the flow of all kinds of fluids such as air, mud, oil, water, steam, liquid …
