The seals material for a solenoid valve is an important role to ensure long working life for solenoid valve . Selecting the correct sealing material for your solenoid valve requires to consider below factors. 1) Chemical compatibility. 2) Temperature of the med ium 3 ) Working pressure and burst pressure XHnotion will describe the most common 5 seal materials available for solenoid valve. 1. Nitrile Rubbe r(NBR /Buna-N) Main used for diaphragm, O rings and seal material, Suitable for air, gas, liquid, water, light oil etc, Fluid temperature -18℃ to 80℃. NBR is the most common and standard solenoid valve seals material. Nitrile Rubber is weak in terms of oxidising media such as acids and poor to resist the sunshine. NBR seals have a good abrasion and tear resistance. (1) NBR seals are most commonly used with the following media: Water, Air, Different Fuels, Oi...
