Be careful when using the electric control valve

Electric regulating valve is an important performance unit surface in industrial automation process control. Youfanggong valve is a new type of material. With the increasing degree of automation in the industrial field, it is being used more and more in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages.

The electric regulating valve is energy-saving (only consumes electricity during operation), environmentally friendly (no carbon emission), and the installation is fast and convenient (no complicated pneumatic pipelines and air pump operation stations are required). The valve is divided into three types: linear characteristic, equal percentage characteristic and parabolic characteristic according to its function and characteristic according to the power used by the actuator.

Matters needing attention in the operation of the device New design and control system of the device, in order to ensure the normal operation of the regulating valve when starting up and the safe operation of the system, before the new valve is installed, check whether the nameplate symbol on the valve matches the design requirements. match. The following items should also be debugged together.

Basic error limit; full stroke deviation; hysteresis; dead zone; leakage (in the case of strict requirements).
