High pressure control valve mainly includes pneumatic high pressure control valve and electric high pressure control valve. The following I will introduce them separately.

 

Pneumatic high pressure control valve mainly aims at the general control valve in high pressure or high causticity working conditions. The research and development of the pneumatic high pressure control valve quickly improve the control valve’s capability. In the bad working conditions, pneumatic high pressure control valve can work in safe, reliable and steady. As the pneumatic high pressure control valve takes the single structure design, medium can import and export from the pipeline with smaller resistance. Owing to this unique capability, pneumatic high pressure control valve can do a good control valve’s job in various high viscosity with suspending or granulate medium. It also has significant effects in the clinkering blockage prevention.

 

Electric high pressure control valve has the same theory as pneumatic high pressure control valve. It can also work in all kinds of high pressure, high-pressure differential and high corrosion conditions. Electric high pressure control valve take the urea system, its service life increase 2 to 3 times than general control valve. Thanks to the electric high pressure control valve adopts the electric actuator with amplifier which can control signal and power source. It mainly uses the single - phase 220V as the power; it can receive 4 to 20mA DC signal; it can automatic control the open and close of the valve so as to become a continuous control valve to control the pressure, flow, temperature and liquid level. Automatic regulating system is the key point of its unique productive process. Electric high pressure control valve widely uses in automatic control system of industry department in oil, chemical, metallurgy, electricity, medical, food and so on.

 

We mainly analyze some characteristic and application of pneumatic and electric high pressure control valve above. Then, we want to introduce the installation considerations of high pressure control valve.

 

High pressure control valve requires the temperature should between -25~60℃ and relative humidity should less than 95%. If the valve install in outdoors or under the high temperature, we should take the waterproof and cooling measure. High pressure control valve primarily use the vertical installation. In some special circumstances,we can also take the slanting installation, but if the  gradient angle is large or the volume and the weight of the valve is heavy, we should take certain supports as the protection. When we install an electric high pressure control valve, we should act according the electrical equipment construction requirements. Remember to add some oiling after we overhaul the actuator of it. Do not install the high pressure control valve far away from the ground, especially not over 1.8 meter than the ground, so as to easily use hand wheel to repair it.
