What are the performance indicators of electric high temperature control valves?

The performance indicators of electric high temperature control valve include basic error, backlash, dead zone, oil leakage, sealing, appearance, power supply voltage change, insulation resistance, pressure strength, rated flow coefficient, inherent flow characteristics, vibration resistance, temperature rise, long-term operation stability, explosion-proof, environmental temperature change and so on. The first nine items are ex-factory inspection items.
Electric high temperature control valve is an important executive unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being more and more applied in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages.

Electric high temperature control valves can save energy (only consume electricity when working), be environmentally friendly (no carbon emissions), and install quickly and conveniently (without complicated pneumatic pipelines and air pump workstations). According to the power of the actuator, the electric high temperature control valve can be divided into three types: linear characteristic, equal percentage characteristic and parabolic characteristic.
