Explosion-Proof Solenoid Valve - MA 3/8"~1/2"

QUEEN SOLENOID VALVES

Discription

MA-P10~15-Ex explosion-proof solenoid valve is equipped with imported Italian explosion-proof coils, certified by ATEX and IECEx. This normally closed, pilot-operated diaphragm solenoid valve features connection sizes ranging from PT3/8" to 1/2" and requires a minimum operating pressure of 0.1 kgf/cm² to open.

​

  • Explosion proof : Ex mb llC T4 Gb、Ex mb lllC T135°C Db.

  • Pilot operated, high flow rate and low electric power consumption only 5.2 w.

  • Suitable for Air, Inert gases, Water, Kerosene oil, Light oil(Below 50 cst).

  • Operating pressure range from 0.1 ~ 16 kgf/cm², quick acting , durable usage.

  • Piping is simple and convenient, applicable to the upright pipe or a horizontal pipe connected unrestricted.

  • The diaphragm can be selected from NBR, EPDM, or VITON.

Seal Material Characteristics

• NBR

∙ Temperature : -5~80°C

∙ Pros : Economical, widely used, with good oil and wear resistance.

∙ Cons : Unsuitable for polar solvents like nitro compounds, ozone, and ketones.

• EPDM

∙ Temperature : -10~130°C

∙ Pros : Resistance to polar solvents (alcohols, ketones, ethylene glycol) and mild acids/bases.

∙ Cons : Not suitable for gasoline, mineral oil, and aromatic hydrocarbons.

• VITON (FPM/FKM)

∙ Temperature : -10~120°C

∙ Pros : Stable, aging-resistant, and resistant to most oils and solvents.

∙ Cons : Costly, not recommended for ketones, esters, or nitro compounds.

Cautions

  • Before installation, please check whether the solenoid valve voltage is consistent with the power supply voltage.
    - AC voltage tolerance: ±10%
    - DC voltage tolerance: ±1%

  • If there are unclean impurities in the fluid, a filter should be installed to avoid reducing the service life and hindering the operation of the solenoid valve.

  • Please install the solenoid valve in the direction of the fluid.

  • Pilot-operated solenoid valves require a minimum pressure to open.

  • Not suitable for freezing fluids.

Certificate

  • CE
