ANSI, ISO, JIS, or Special Flanges

Vacuum Research valves are available with virtually any flange or combination of flanges at no extra charge. Combinations of ISO on one flange and ANSI on the other are easily accommodated. Even different sizes such as 4 inch on one flange and 6 inch on the other.

High Conductance

Vacuum Research’s large port design introduced over 35 years ago provides exceptionally high conductance. Port sizes to the maximum for ANSI, ISO and JIS flanges give full speed from your cryo, turbo, or diffusion pump.

Satisfaction Guaranteed

Vacuum Research has been building high vacuum valves for almost 50 years and has earned a reputation for world class product quality and customer service. If you are not satisfied with your Vacuum Research valve just send it back.

Long Life

More than 250,000 cycles for aluminum valves. That’s one cycle every 2 minutes, 24 hours/day for a year. An optional million cycle design is available.

Vacuum & Pressure

Vacuum Research Valves stay sealed against positive pressure in either direction. Seal and open with up to 3 atmospheres differential pressure.

Electric Motor, Air or Manual Actuators

All Vacuum Research gate valves are available with 3 types of actuators. Manual actuators are the least expensive. Electro-pneumatic actuators use 70 psi (4.9 kg/cm) compressed air and include the solenoid (specify the solenoid voltage that is most convenient for you). Electric motor actuators use high torque servo motors and operate from 115V or 230V, 1Ø 50 or 60 Hz. CE Mark included.

Roughing and Gauge Ports

There are six locations for optional gauge and roughing ports described in Optional Features.

Position Indicators, Limit Switches

Visual position indication of valve position is included on all valves. Limit switches for remote indication are described in Optional Features.
