Nor-Cal Products’ stainless steel gate valves share with our poppet valves the innovative design, highest grade materials and superior workmanship that has made us a major supplier of valves to the vacuum industry. The estimated service interval on these valves is 100,000 cycles, depending on the application. Our linear gate valves have an ultra-slim profile, which makes them perfect for applications where space is limited and their smaller volume results in lower outgassing and faster pump down. Larger sizes have a unique feature in the actuator; this dampens the vibration, which can arise when the gate is opened. This makes these valves ideal for semiconductor and other vibration sensitive processes. Nor-Cal gate valves are available with NW (ISO-KF), ISO (clamp and bolt type), CF and ASA flanges in port sizes from 5/8 to 12 inches (16-300mm). Larger sizes are available upon request. Choose from manual or pneumatic actuation and Viton or copper seal bonnet.
