Hi, this is little control in the butler, to bring us today is the difference between electric regulating valve and pneumatic control valve, electric control valve and its basic error sensitivity of 0.3%, in other to establish gas source, not meeting the requirements of explosion-proof high occasions, pneumatic control valve and its basic error and the sensitivity of 0.5%, but also to establish another air supply station, but its essence safety, suitable for explosion-proof demanding situations, then we have a detailed look at what they have their own characteristics,

Electric control valve
Electric control valve made up by electric actuator and control valve:
1, light weight, fine appearance,
2, the function of many alternative function is not complete products, make the model simplification, solved the factory management complex, selection of complex, maintenance workload big shortcoming,
3, the adjustable of electric control valve, generally can reach 100, and from 10% to 90% of the opening all can guarantee good regulatory,
4, action smoothly, high reliability, can solve the traditional valve leakage big fatal defect structure,
5, on and off features excellent, leakage quantity is zero, to solve the traditional valve leakage big fatal defect structure,
6, good ability to overcome the pressure difference, prevent function, no adjustment,
7, electric regulating valve of flow characteristic is approximate equal percentage, and the actual work flow characteristic, because there is always before the valve, the valve after pressure difference, traditional regulator of the actual curve will happen a lot of distortion is small, so it not only has good regulation performance, but also has good economy and energy saving,
8, compared with the pneumatic control valve, electric regulator with the power supply is both convenient and save, save the building air station, a series of trouble,
9, electric regulating mechanism of high precision and resolution can reach 1/1000, low operating cost, no maintenance,
10, according to actual use environment, use four fluorine lining of ceramic ball valve or fully lined ceramic hard seal ball valve, in order to obtain higher corrosion resistance and wear resistance properties,

The pneumatic - valve
Pneumatic control valve by pneumatic actuators and valve combination:
1, the extrusion of high strength aluminum cylinder, the inner surface by fine grinding and hard anodic oxidation treatment, long service life, low friction coefficient, quickness,
More than 2, compact elegant, modern modelling, specifications of the products to make selection more economical,
3, choose high quality bearing surfaces of all activities, low friction, long life, no noise,
4, external installation of two separate trip regulating mechanism, convenient for plus or minus 5 degrees fully open or close position adjustment,
5, the piston and the end cover adopt the die casting aluminum alloy, high strength, light weight,
6, change the packing, can be used in high temperature or low temperature situation,
7, according to the need to provide a variety of angular travel and three type pneumatic actuators,
8, easy control, and intrinsically safe, do not need another explosion protection measures,
9, but the basic error and sensitivity, low is in need of improvement,

Finished,
