Simply put, the Check Valve controls the Universal Valve through an electric actuator to open and close the Universal Valve. This is divided into two parts, the upper part is the electric actuator, and the lower part is the Universal Valve. The operating force distance is larger than that of the Check Valve, and the operating speed of the electric shutter valve switch can be adjusted. The structure is simple and easy to maintain. Due to the buffering characteristics of the gas itself during the action process, it is not easy to be damaged due to blockage, but the control system that requires a gas source is also larger than the stop valve. The return valve is complicated. The electric shutter valve is responsive, safe and reliable. Many factories with high control requirements have set up compressed air stations for pneumatic instrument control components. Electric is a device that requires electricity and can control flow.
1. The Universal Valve adopts a pressure self-connecting seal or a Universal Valve body and Universal Valve cover sealing structure, which is reliable and reliable! Safe and reliable.
2. The double valve adopts a universal top structure in the middle of the double shutter plate, which can automatically adjust the fit of the sealing surface of the valve and the valve seat to ensure the sealing of the valve. At the same time, this structure is easy to maintain, saves costs, and has good valve exchangeability.
3. The valve seat sealing surface is made of cobalt-chromium-tungsten carbide formed by plasma welding. The sealing surface has high hardness, is wear-resistant, abrasion-resistant, and has a long service life.
4. The
Valve Stem is made of nitrogen-permeated steel and has been surface nitrided. It has high hardness, is scratch-resistant, corrosion-resistant, and has a long service life.
5. The electric device has a torque control mechanism, an on-site operating mechanism and a manual and electric switching mechanism. In addition to on-site operation, it can also perform remote operation, PLC control, 4~20mA current input and output intelligent control, etc.
6. The handle of the manual valve opens when the manual mechanism or collision occurs. Reduce the operating force of the Universal Valve.
7. The Universal Valve can be installed at any position in the pipeline, and carbon steel or alloy steel valves can be selected according to the medium and the temperature of the medium.
Check Valve operating principle: Check Valve are usually connected by an electric actuator and a Universal Valve, and become a Check Valve after installation and debugging. The Check Valve uses electric energy as power to connect the electric actuator to drive the Universal Valve to realize the switching and regulating actions of the Universal Valve. In order to achieve the purpose of switching or adjusting the pipeline medium.
Working nature: The Check Valve is generally driven by a motor, which is relatively resistant to voltage shock. Solenoid valves are quick-opening and quick-closing, and are generally used in places with small flow rates and small pressures that require high switching frequency. The opposite is true for Check Valve. The opening of the Check Valve can be controlled, and its states include open, closed, half-open and half-closed. It can control the flow of the medium in the pipeline but the
Solenoid Valve cannot meet this requirement. Pneumatic Check Valve: A Universal Valve driven by compressed air.
