Product Name Notes
A mating pair of ASA flanges is made up of a smooth faced flange and a grooved flange. A Viton O-ring of a size appropriate for the diameter and depth...
Genesis stainless steel valves offer million cycle reliability, combined with an integrated low cost soft start option. Genesis stainless steel valves are electropolished to optimize conductance.
Genesis valves offer million cycle reliability combined with a highly configurable valve body. Aluminum modular valves have a small footprint, allowing them to be placed where they are needed. Available...
Leak valves are used for controlling gas introduction into high and ultra-high vacuum systems. These valves utilize an optically flat sapphire poppet and a metal seat, allowing bakeout temperatures to...
Nor-Cal aluminum bodied pendulum valves offer the user an alternative to traditional linear gate valves. Fewer moving parts and less metal to metal contact means reduced particle generation and wear.
Nor-Cal copper sealed manual valves have a vacuum range of 1x10-10 Torr. Nor-Cal poppet valves are fully opening for increased conductance. Valve bodies are electropolished for better corrosion resistance...
Nor-Cal copper sealed pneumatic gate valves have a vacuum range of 1x10-10 Torr. Nor-Cal gate valves have a slim profile, shorting the gas path. Nor-Cal gate valves are electropolished...
Nor-Cal copper sealed pneumatic valves have a vacuum range of 1x10-10 Torr. Nor-Cal poppet valves are fully opening for increased conductance. Valve bodies are electropolished for better corrosion resistance...
Nor-Cal elastomer sealed manual valves have a vacuum range of 1x10-9 Torr. Nor-Cal poppet valves are fully opening for increased conductance. Valve bodies are electropolished for better corrosion resistance.
Nor-Cal elastomer sealed pneumatic gate valves have a vacuum range of 1x10-9 Torr. Nor-Cal gate valves have a slim profile, shorting the gas path. Nor-Cal gate valves are electropolished...
Nor-Cal elastomer sealed pneumatic valves have a vacuum range of 1x10-9 Torr. Nor-Cal poppet valves are fully opening for increased conductance. Valve bodies are electropolished for better corrosion resistance.
Nor-Cal's bakeable all-metal seal angle valves are intended for use in UHV or cryogenic applications where temperature extremes preclude the use of our elastomer seal valves. Approved for use in...
Nor-Cal?s 3-position gate valves employ two pneumatic solenoids and an air pressure regulator to achieve the three positions of fully open, fully closed, and an adjustable third position. One solenoid...
Our poppet valves are fully opening for high conductance and to prevent bellows contamination while the valve is in the open position, reducing particle contamination when the valve is cycled.
Quarter-turn actuation, small footprint and the shortest possible gas path make manual butterfly valves the preferred choice for many applications. O-ring sealed plate and stem provide a low-cost alternative to...
The N Series Valves feature high cycle life and a small footprint in right-angle and in-line body styles. Constructed of Stainless Steel with NW16, 25, 40 and 50 flanges. All...
The simple, robust design of ball valves provides high reliability vacuum line isolation in dirty applications. The pneumatic / spring operated ball valve is ideal for difficult-to-reach areas and also...
Traditional 3-position valves accomplish vacuum isolation and rough pressure control via an adjustable air cylinder. Unfortunately, the single, mid-open set point is neither accurate nor repeatable. Nor-Cal?s 3-position throttling pendulum...
