OKEExplosion-ProofSolenoid ValveOverview

Imported explosion-proof solenoid valves (Explosion proof solenoid valve) are suitable for flammable and explosive media, as well as automatic switching of pipeline media in hazardous locations. Examples include gases or other fluids such as natural gas, coal gas, liquefied petroleum gas, etc. The explosion-proof solenoid valve encloses all components that may ignite gas mixtures within a housing. This housing can withstand the penetration of combustible mixtures through any joint or structural gap into the interior without damage and without causing ignition of the external environment formed by one or more gases or vapors. Components that may generate sparks, arcs, or hazardous temperatures are all placed inside the flameproof enclosure, which isolates the internal space of the equipment from the surrounding environment. The flameproof enclosure has gaps, and due to the breathing effect of electrical equipment and gas permeation, gas mixtures may exist inside.

Normally Closed: When the coil is energized, the electromagnetic core is attracted, the pressure relief port opens, and the main piston is pushed by the medium pressure to open the main valve port, allowing medium flow.
When the coil is de-energized, the main valve port closes, and the medium is cut off.
Normally Open: When the coil is energized, the electromagnetic core is attracted, the pressure relief port closes, and the main piston is pushed by the medium pressure to close the main valve port, cutting off the medium.
When the coil is de-energized, the main valve port opens, allowing medium flow.

OKEExplosion-ProofSolenoid ValveFeatures

1. Can be freely installed on-site; rapid response action; uses original sealing materials, with a lifespan ten times that of similar products.
2. Processed by CNC machine tools to ensure precision and reliability of the solenoid valve.
3. Utilizes specially plastic-encapsulated coils to improve valve reliability and provide waterproof and moisture-proof capabilities.
4. Suitable for liquids, gases, and oils, expanding the valve's application range.
5. Manual handle switch allows the solenoid valve to be opened and closed when the coil is de-energized or burned out.
