Filterchem Air-Operated Valves are ideal for automated control of liquids, featuring fail-safe operation with normally-closed as the standard configuration. This valve requires a minimum of 30 psi air pressure for actuation. Similar in design to that of the Filterchem foot-operated valve, this valve is an economical and compact alternative to more expensive air-operated diaphragm or ball valves. Filterchem Air-Operated valves are of molded construction from either Type 1 PVC or natural polypropylene, and contain the following internal components: Viton® O-ring seal, high-density polyethylene piston and a Kynar®-coated return spring.
• 125 psi @ 75°F for all models • PVC valves for applications up to 140°F • Polypropylene valves are for applications ranging to 180°F • Mounting holes in base plate - mount valve horizontal or vertical
Plast-O-Matic Series MFR is the answer for handling pure de-ionized rinse water where your hands must be free to handle the part being rinsed. They are also ideal for handling corrosive or other ultrapure liquids where economical performance is a prime consideration. Series MFR self-closing valves are normally-closed and require a minimum of palm, foot or knee pressure to open. Double u-cup seals are used on the shaft to isolate the spring from the process fluid. Maximum working inlet pressure of 150 psi @ 73°F. Series MFR valve bodies are made from Type 1, grade 1 PVC with seal materials in FKM and EPDM. The spring (non-wetted) is stainless steel.
