Nor-Cal 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 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 pumpdown. Larger sizes have a unique feature in the actuator which dampens the vibration which can arise when the gate is opened. This makes these valves ideal for semiconductor and other vibration sensitive processes. The carriage assembly and actuator can be removed without disassembling the body from the system for easy maintenance. The 304 stainless steel bodies are vacuum furnace brazed to 1100°C at 10^-6 Torr before being electropolished inside and out. The welded AM-350 bellows have a short stroke for a longer cycle life.

Nor-Cal gate valves are available with NW (ISO-KF), ISO (clamp and bolt type), CF and ASA flanges in port sizes from 1.5 to 12 inches. Larger sizes are available upon request. Choose from manual or pneumatic actuation and Viton^® or copper seal bonnet.

Bakeability

Nor-Cal gate valves with Viton^® seal bonnet and gate and standard Reed-switch position indicators are bakeable to 150°C, as long as the actuator is not baked above 60°C. A gate valve with copper seal bonnet, Viton^® gate and micro-switch option can be baked to 200°C, except for the actuator. With the air solenoid and position indicators removed, a copper seal bonnet valve with high temperature Kalrez^® gate O-ring can be baked to 250°C with the gate in the open position. Silicone heater jackets for bakeouts up to 200°C can be provided. Please ask your Nor-Cal representative for pricing.

Air Solenoid Options

All pneumatic gate valves come standard with a 4-Way, 120V, 50/60Hz air solenoid. Solenoids are mounted on all Viton seal bonnet gate valves with four inch ID and larger. Solenoids for Viton seal bonnet gate valves with under four inch ID and all sizes of copper seal gate valves are shipped unmounted with the valve. Solenoids for these valves can be provided mounted with an optional mounting bracket for an additional $55.00. Specify when ordering. Specify other Air solenoid options by adding the correct suffix to model number. See the Valves PDF catalog (link below) for more information.
