Product Description

SZDLP electronic electric regulating valve
Overview of SZDLP electronic electric regulator
SZDLP electronic electric single-seat regulating valve, SZDLM electronic electric sleeve regulating valve, accept the DC current signal to adjust the instrument, change the flow of the adjusted medium, so that the controlled process parameters remain at the given value. Widely used in electric power, metallurgy, chemical industry, petroleum, textile, pharmaceutical, paper and other industrial sectors of production automation control. Electronic electric regulating valve nominal diameter from 20 to 300mm, nominal pressure is 1.6, 4.0, 6.4MPa, accepting signal is 0 ~ 10mA.DC or 4 ~ 20mA.DC, the use of temperature range from -40ºC ~ 450ºC. The electric single-seat regulating valve is suitable for small pressure difference, medium viscosity or slightly granular impurity occasions; Electric sleeve regulating valve is suitable for large pressure difference and large leakage occasions.

Electric regulating valve has the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics, easy maintenance and so on. The whole valve has the characteristics of smooth work, large allowable pressure difference, accurate flow characteristics and low noise. Especially suitable for small leakage, large pressure difference before and after the valve in the workplace. Electrical regulating valve in maintenance, need to check the key parts of what? The analysis is as follows:
1, check the valve seat of the electrical regulator: due to the work of the medium infiltration, fixed valve seat with the internal surface of the thread is easy to be corroded and the valve seat relaxed;
2, check the valve spool: the valve spool is one of the movable parts of the regulator, the erosion of the medium is more serious, the maintenance to carefully check whether the parts of the valve spool are corroded, wear, especially in the case of high pressure difference, the valve spool wear caused by cavitation cavitation phenomenon is more serious. The valve spool which is seriously damaged should be replaced; Check the sealing packing: check whether the asbestos rope is dry, such as the use of PTFE packing, should pay attention to check whether the aging and its mating surface is damaged;
3. Check whether the rubber film in the actuator of the electric regulating valve is aging and whether there is cracking phenomenon.
4, check the internal wall of the electrical regulating valve: in the occasion of high pressure difference and corrosive media, the inner wall of the valve body, the diaphragm of the diaphragm valve is often affected by the impact and corrosion of the medium, must focus on the inspection of the pressure and corrosion resistance of the regulating valve order notice
Instructions for ordering
