High Flow Vacuum Valves For Medical Applications:-Image

Peter Paul Electronics Co., Inc., New Britain, Connecticut, has announced the development of a new series of solenoid valves for use in vacuum chambers for sterilizing medical instruments. These valves feature high flows; bubble-tight sealing; standard vacuum fittings and standard flanges for international use; electron beam seamless welding of flange to body; purity requirements allowing no trapped particles on the inner diameter; several million cycle endurance for critical life operation; and TeflonTM outside coating to eliminate dust and possible wear-creating particles.

Two basic models have been developed: The smaller one is electrically operated with 1/2" orifice, 2-Way Normally Closed, FKM plunger seal and static seal material.

The larger of the new valves is air-operated by cylinder with a 1" orifice to meet high-flow requirements. The spring-loaded assembly seals on the orifice for failsafe operation. Assembly of this larger unit also involves electron beam welding. Both valves employ anodized aluminum bodies with all stainless steel inner moving parts. Of particular interest to prospective users, a major medical products producer required elaborate testing of valve open/close times, as well as extensive endurance testing.
