Electromagnetic valve lectotype attention its applicability

The electromagnetic valve is used in the pipeline fluid must and series model calibration in the medium. Electromagnetic valve is used in the fluid temperature must be smaller than the calibration temperature. Solenoid valve to allow the liquid viscosity, generally under 20 CST, more than 20 CST shall be indicated. Work pressure differential, high pressure pipe * sent in less than 0. 04 mpa should be chosen as ZS, 2 w, ZQDF, ZCM series and type of moving step by step straight acting; * low working pressure difference is greater than zero. 04 mpa can choose differential solenoid valve; * high work pressure difference should be less than the electromagnetic valve * pressure calibration; General solenoid valve is a one-way work, so should pay attention to whether there is a pressure difference, install the check valve. Fluid cleanliness is not high when the filters should be installed in front of the solenoid valve, general solenoid valve is better claim to medium cleanness. Pay attention to the traffic pore size and diameter; Two solenoid valve usually only switch control; Conditions permit, please install bypass pipe, easy maintenance; When there is water hammer to customize solenoid valve opening and closing time to adjust. Power supply current and power consumption should be selected according to the output capacity, power supply voltage generally allow + / - 10%, must pay attention to communication when starting the VA value is higher.
