ZCSTH self-holding solenoid valve DN15-300MM

First, the self-holding type solenoid valve - Purpose: Shanghai Zhen ZCSTH self-holding type solenoid valve cooling water tablets station control system replacement hydraulic valve-specific products. Widely used in hydropower, dyeing, textile, printing and dyeing, food, cigarettes, cement products, petrochemicals, metallurgy, residential water and other departments and other various industrial sectors piping system. Second, the self-holding type solenoid valve - solenoid pilot valve works self-holding type having a mechanical self-locking memory double-pilot structure. As part coil "B" is energized, the solenoid valve is opened, then off, then the solenoid valve is normally on state, when the component coil "A" is energized, the solenoid valve is closed, then off, when the solenoid valve is normally closed. If the coil "A", "B" is energized at the same time, when the solenoid valve is a normally-on state, the coil will not result in burn, so that the valve is a dual coil self-holding type liquid water solenoid valve replacement update product Third, self-holding solenoid valve - Features: electromagnetic part, seal-wide adoption of special high temperature electrical materials and sealing materials, and the use of a simple and effective insulation measures and compact structure, combines the advantages of direct-acting and pilot indirect products It can reliably work under low pressure or differential pressure of zero cases a reasonable selection, guidance suite valve cup and clever use of fluid lubrication, reduce wear and increase life expectancy. Fourth, self-holding type solenoid valve - technical parameters Working medium liquid water, air, oil, steam, distilled water medium temperature ℃ ≤180 nominal working pressure Mpa 1.6 Mpa 0.1-0.8 \ 0.1-1.6 supply voltage AC220V DC24V other specifications can be used for special orders Rated flow coefficient KV according to JB / T7352-94 predetermined amount of leakage ml / min according to JB / T7352-94 · F predetermined nominal diameter (DN150 or less) mm DN25-DN300 Power VA small coil AC≤36VA DC≤ 20W, large coil (DN150 or less) AC≤50VA DC≤35W explosion proof mark within ExmIIT4 license number GYB071325X Outlet connection thread M20 × 1.5 or 1.5 meters proof lead ambient temperature -5 ~ + 60 ℃ (not frozen)
