SZDLQ electronic electric three-way combination regulating valve and SZDLX electronic electric three-way shunt regulating valve are guided by cylindrical thin wall window spool. With 9610L series electronic direct travel electric actuator, accept 0 ~ 10 or 4 ~ 20mA.DC signal drive valve opening and closing. The three-way convergent regulating valve is used to mix two kinds of fluid, or the same fluid at different temperatures, into the same temperature fluid. The three-way diverter valve divides a fluid into two fluids.
Electronic regulating valve nominal diameter from 25mm to 300mm, electronic regulating valve nominal pressure is 1.6, 4.0, 6.4MPa, electronic regulating valve for fluid temperature from -60ºC to 450ºC, electronic regulating valve control signal is 0 ~ 10 or 4 ~ 20mA.DC. With different valve covers can be divided into ordinary type and heat dissipation type two.

1, check the valve seat of the electrical control valve: because of the medium infiltration when working, the internal surface of the screw thread used to fix the valve seat is easily corroded and the valve seat is 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 electrical regulator between the internal wall: in the occasion of high pressure difference and corrosive media, the inner wall of the valve body, diaphragm valve diaphragm often by the impact and corrosion of the medium, must focus on checking the pressure and corrosion resistance.
