Product details
Product Introduction:
Fluid media: air, nitrogen, natural gas, liquefied petroleum gas, hydrogen, gas, biogas, coal gas, etc
Nominal pressure: PN16 (using 0-0.1, 0.6, 1.6, 2.5MPa)
Nominal diameter: DN25-DN500mm
Valve body material: stainless steel (304, 316), cast steel, cast iron (HT200)
Standard voltage: pulse AC220V DC24V、DC12V
Coil connection method: Explosion proof cover three core sheathed cable lead type, plug type
Leakage rate: zero leakage
Working principle: This product is generally used in conjunction with a leak alarm. In the event of a gas leak or emergency shutdown, the host sends a pulse power signal to the solenoid valve, which cuts off the gas supply within 1 second, effectively preventing accidents. After eliminating the danger, the solenoid valve protective cover is manually opened and the valve is manually opened! Normally open solenoid valve: manually unscrew the protective cover, lift the handle ball upwards to open the valve. When gas leaks, the coil is energized and the solenoid valve instantly closes. Regardless of how the solenoid valve is energized, it must be manually opened after eliminating the danger!

Nominal diameter: DN25-DN500mm
Valve body material: stainless steel (304, 316), cast steel, cast iron (HT200)
Standard voltage: pulse AC220V DC24V、DC12V
Coil connection method: Explosion proof cover three core sheathed cable lead type, plug type
Sealing performance: temperature resistance, pressure resistance, wear resistance, anti-corrosion connection method flange, thread, welding
Sealing method: flat and conical plane sealingLeakage rate: zero leakage
Performance characteristics: high sensitivity, strong dynamic sealing, high safety, long service life.
Scope of work: Gas alarm automatic control system and pipelines that require emergency shutdown.
Note: 1. Before installing the solenoid valve, impurities and welding slag in the pipeline must be cleaned to avoid leakage inside the valve body.
2. The solenoid valve can only be installed horizontally under normal working conditions, and it needs to be explained in advance when installed vertically.
3. After the installation of the solenoid valve is completed, it should be operated several times before it can be put into use.
Explosion proof coil description: Explosion proof solenoid valves are solenoid valves that operate in relatively special environments, and users must choose solenoid valves according to national explosion-proof standards. To ensure the safety of life and property. The explosion-proof solenoid valve produced has passed the inspection of the National Explosion proof Electrical Product Quality Supervision and Inspection Center and obtained the explosion-proof solenoid valve product qualification certificate.
Explosion proof grade: EXd Ⅱ CT5. Explosion proof certificate number: CNEX12.0353
Manufacturing standards: GB3836.1-2010、GB3836.2-2010
