Nor-Cal Products Flanges, Fittings, and Accessories Catalog Section

(PDF - 17.9 MB)

This section of the catalog includes our selection of Flanges, Fittings, Hardware, Adapters, and Accessories. Click HERE to shop our online store.

Our flanges are made from 304 stainless steel material, which is specially processed to reduce impurities, grain size and microscopic leak paths. They are available in all commonly used high and ultra-high vacuum flange types, including ASA, NW (ISO-KF), ISO, CF and wire seal flanges. We also offer chain clamps and metal seals to convert a high vacuum NW flange to ultra-high vacuum.

Flange-to-Flange and Flange-to-Fitting Adapters
Nor-Cal Products provides a broad range of adapter fittings in order to connect two dissimilar types of components. They are made from 304 or 316L stainless steel and are TIG welded, cleaned and leak checked for vacuum service. Tube finishes are normally bead blasted. However, tumbled or electropolished finish can be provided upon request. Flanges and nipples used to adapt different sizes of the same flange type are called reducers. 

Weld Fittings
Fittings are available with or without flanges. Weld fittings (without flanges) are typically sold to mechanical contractors for use during the fit up phase of new fab construction. Nor-Cal Products provides a broad range of adapter fittings in order to connect two dissimilar types of components. They are made from 304 stainless steel and are TIG welded, cleaned and leak checked for vacuum service.

Flexhose, Couplings and PVC hose
Flexible stainless steel hoses are available in three thicknesses to accommodate many applications and bend radius requirements. Nor-Cal’s flexible couplings have more convolutions than comparable products, resulting in greater flexibility and lower spring rates. Plasticized PVC hoses can be used as a low cost rough vacuum line. 

304 & 316L Stainless Steel Tubing
Nor-Cal’s consumption of stainless steel tubing for its own products makes it possible to offer 304 and 316L stainless steel tubing in lengths up to 20 feet. 304 stainless steel tubing standard finishes are white pickled (Number 1 unpolished), bright annealed or polished OD and ID, depending on the size. 316L stainless steel tubing is offered with a bright annealed finish only. Bright annealed and polished tubing has been pickled and passivated. Polished tube can be described as No. 4 polished. The surface meets ASTM A270, and has received a 150 grit polish on the OD and 180 grit on the ID. Special cleaning, materials and surface finishes are available for an additional charge.

Nor-Cal Products Isolation Valves Catalog Section

(PDF - 10.7 MB)

This section of the catalog includes our selection of Linear Gate Valves. Click HERE to shop our online store.

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 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.

This section of the catalog includes our selection of Pendulum Valves. Click HERE to shop our online store.

Nor-Cal Products’ pneumatically actuated isolation pendulum valves contain the same patented Penduroll mechanism that is found in the Intellisys^TM throttling pendulum valves. These valves offer the user a highly reliable, compact and low cost alternative to competitive designs. In addition, the smooth actuation results in low particle generation and rapid open-to-close speeds.

Nor-Cal Products Isolation Poppet Valves Catalog Section

(PDF - 10.7 MB)

This section of the catalog includes our selection of standard Isolation Poppet Valves, N-Series, and replacement kits. Click HERE to shop our online store.

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. Our bodies are die-formed from 304 stainless steel to eliminate sharp inside corners and improve conductance. The valves are electropolished for lower outgassing and better corrosion resistance. The welded bellows are made from AM-350 stainless steel to provide excellent corrosion resistance and flexibility. They are designed with additional segments to provide extended life.

Nor-Cal Products Ball Valves Catalog Section

(PDF - 10.7 MB)

This section of the catalog includes our selection of Ball Valves. Click HERE to shop our online store.

Ball valves are a low cost, manually or pneumatically operated, straight through isolation device. Their simple, robust design provides high reliability in “dirty” applications. They are commonly used on MOCVD and CVD equipment downstream from the chamber or vacuum pump to isolate traps or abatement tools. A stainless steel body and PTFE seat make these valves ideal for corrosive environments. Other applications include vacuum and other facilities requirements.

Nor-Cal Products Manual Butterfly Valves Catalog Section

(PDF - 10.7 MB)

This section of the catalog includes our selection of Manual Butterfly Valves. Click HERE to shop our online store.

Our manual butterfly valves provide a low-cost alternative to bellows sealed gate valves. These valves easily actuate from the fully-closed position to fully open with only a quarter turn of the knob. A patented design allows the sealing disk to center itself when closing, with even pressure around the FKM O-ring seal. This design also helps to lower the amount of scuffing or rolling of the O-ring. Quarter-turn actuation, small footprint and the shortest possible gas path make manual butterfly valves the preferred choice for many applications.

Nor-Cal Products All Metal and Leak Valves Catalog Section

(PDF - 10.7 MB)

This section of the catalog includes our selection of All Metal and Leak Valves. Click HERE to shop our online store.

Nor-Cal Products 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 beamline facilities, these valves have a temperature operating range from -250°C to 400°C. Leak valves are used for controlling gas introduction into high and ultra-high vacuum systems. They utilize an optically flat sapphire poppet and a metal seal seat, allowing bakeout temperatures to 450ºC.
