Key High Vacuum Products, INC.’s model PEV-1 piezoelectric gas flow valve is manufactured from high-quality vacuum compatible materials. The valve features:
- Piezoelectric crystal bender element which responds directly to a voltage signal, causing the opening and closing of the valve.
- Constructed of 304 stainless steel, the valve is ideally suited for vacuum sputtering, ion physics, mass spectrometry and many other applications related to gas flow or pressure control in vacuum systems.
- Fail-safe construction, so that in the event of a power loss the valve will automatically close and remain closed until power is restored.
