ZCZP flange steam solenoid valve DN15-300

Shanghai Zhen ZCZP steam solenoid valve is pilot operated solenoid valve open the second auxiliary valve and the main valve composed of two parts. It is by opening and closing the auxiliary valve to control the main valve off. Depending on the state in which the switch when power can be divided into a normally closed solenoid valve and a normally open solenoid valve. Normally closed solenoid valve, in paragraph point regular position, the vice valve port closed, the main valve was open circuit, when the electrical signal into the pilot valve coil, the movable core electromagnetic force attracted by the open vice valve port, the main valve cup pressure guide speed disappear, the media pressure on the main valve cup holder, open the main valve, the working medium can circulate. But when the electrical signal disappears, the movable core reset, vice valve port closed by the working medium from the balance hole into the valve, when the pressure tends to balance, by the main valve spring, valve cup weight and medium pressure valve cup down , tight shut the main valve port, valve there was a closed state. Normally open solenoid valve, normally when de-energized position, a spring effect, vice valve port is opened, the main valve circulation. When the electrical signal into the secondary valve coil core activities should be drawn down by Electromagnetic, when the pressure tends to balance, by the main valve spring, valve cup weight and medium pressure valve cup down, tightly seal the valve port, valve It was closed. When the main valve power, the electromagnetic force disappears, Vice find open valve, the main valve cup pressure quickly disappear, the media pressure on the main valve cup holder, open the main valve port, medium flow, the valve was turned ZCZP steam solenoid valve Overview : ZCZP steam solenoid valves are suitable for steam as the heating medium, the temperature control of the executive agency. Steam boiler steam pipes can heaters, radiators, steam dryers and other equipment and various types of temperature-controlled instrument, steam setting machine, steam engines, steam resurgence machines and other equipment were two automatic control and remote control. Widely used in dyeing, textile, printing, food, medicine, cigarettes, cement products, petrochemicals, metallurgy and other sectors of the automatic control system. 1, Heat: electromagnetic part, the seal section with special high temperature electrical materials and sealing materials, and the application of various insulation measures. 2, wear: a reasonable selection, guidance suite valve cup and clever use of the role of fluid lubricant, reducing wear and tear. 3, anti-condensation: the condensing steam pipes are important factors affecting the operation of the steam solenoid valve, this valve will not affect ZCZP condensate steam solenoid valve technical parameters: media type steam, liquid at room temperature, gases, hot liquid, gaseous media Temperature (℃) ≤200 workers said pressure (Mpa) 1.6 Power supply voltage AC220V · DC24V remaining specifications can be used for special orders nominal diameter (mm) 15 20 25 32 40 50 65 80 100 125 150 200 250 300 350 flow coefficient Kv value 2.8 5 8.5 1,218,284,570,110,180,250 60087010001320 Working Pressure (Mpa) 0.04 ~ 1.6 0.1 ~ 1.6 Power VA 4030 50 Body material cast steel and stainless steel
