Valves for Semiconductor and Processing Applications
Valves are crucial in semiconductor and other processing environments, primarily used to isolate pumps and sample entry locks from high vacuum (HV) or ultra-high vacuum (UHV) work chambers.
Features:
- Flange Types: Available in KF, ISO, and ASA/ANSI Flanged configurations, operating effectively in the atmosphere to the 10⁻⁹ torr pressure range, and bakeable up to 150°C (in the open position).
- Material: Made of general-purpose electropolished stainless steel.
- Brazing: Vacuum brazed at 1,100°C to ensure reliable operation under HV and UHV conditions.
- Design: Compact design offering high conductance.
- Operation: Shock-free with minimal vibration, rated for 100,000 cycles before maintenance is required.
- Operation Type: Available in both manual and pneumatic options.
- Safety: Pneumatic valves automatically close or remain closed during power loss or air pressure loss.
- Indication: Models with a 1.5″ flange O.D. and larger feature magnetic REED switches for position indication.
- Solenoid Operator: Pneumatic valves come with a 120VAC solenoid operator at no extra charge, with options for other AC and DC voltages available upon request.
