Scientific & Industrial Diaphragm Isolated and PTFE Solenoid Valves and Components


Utilizing elastomeric or PTFE flexible diaphragms and bellows, the Valcor Scientific family of Diaphragm Isolated Solenoid Valves do not allow contact of the fluid or gas being handled with the valves internal metal operating parts. Paired with polypropylene or PTFE bodies, these highly inert ‘dry solenoid’ valves offer the utmost in dependability where ordinary general-purpose ‘wetted’ valves typically fail.


The chemically inert design inherent in our diaphragm isolated solenoid valves make them an ideal choice where no metal contact of the media, or areas of entrapment, can be tolerated. Well suited for high purity, corrosive, viscous and abrasive fluids, our valves can be found on medical sterilizers, water treatment systems, food processing equipment, and chemical and process analyzers.
