Order Information

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

1. Before installation, please check whether the solenoid valve voltage is consistent with the power supply voltage.

  • AC voltage tolerance: ±10%

  • DC voltage tolerance: ±1%

2. 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.

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

4. Not suitable for frozen fluids
