1405 Type Electronic-Type Electric High Pressure Angle Regulator

Electronic-type electric angle high pressure regulator is the electric actuator in the electric unit

combination instrument. Mainly used for high pressure, high temperature and high pressure

pipelines. Flow rate of fluid media (liquid, air, air-liquid mixture, steam) can be changed, so as to

achieve the regulation of medium pressure, flow rate and other process parameters. The main

difference between it and normal regulator is that it uses high temperature and high pressure

resistant shell materials, high temperature and high pressure resistant, anti-air etching, anticavitation valve inner parts materials, and more precise manufacturing processes. According to

the user's specific working conditions, it adopts single-stage and multi-stage pressure drop type

to minimize the scouring and noise of the fluid to achieve stable regulation of the fluid and

improve the service life of the valve itself. Therefore, the valve has the advantages of complex

structure, stable performance, reliable operation, large allowable differential pressure, low noise,

closed tightly. It has been widely used in petrochemical, power station, metallurgy and other

industrial process of automatic regulation and remote control.

Structure and working principle

Electronic-type electric angle high pressure regulator is composed of two parts: electric actuator and angle

high pressure regulator.
