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
-
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.
-
Not suitable for frozen fluids
