Any application where a clean (non-viscous) processmedia, such as very clean liquids/gases/light oils need to be controlled.

Simple on/off valves are the most popular as many processlines only need flow or no flow.  Solenoid valves can be used infactories/plants where compressed air is not available. They can also be usedin place of larger valves such as electrically actuated ball valves, butwithout taking up anywhere near as much space. Operation is also much quickerthan other valve technologies.

Other solenoid operated valves use a more advancedtechnology meaning they can be used to proportionally control flow or pressuredepending on a varying input signal. This is where another component furtherdownstream needs a specific pressure or flow to maintain the correct workingconditions. Most common input signal used would be a 4-20mA loop signal whichmost factories will have at their disposal usually controlled by a PLC orsimilar system.

Many different valve body and seal materials areavailable, ranging from Brass, Cast Steel, Aluminium and Stainless Steel.Standard seals are usually NBR (Buna Nitrile) but EPDM and PTFE available formore corrosive environments. Material choice all depends on the media goingthrough the valve. If you are unsure on the optimum material for yourapplication, it is always best to talk it through with a Norgren technicalspecialist first.
