Evans Components, Inc. was the first to introduce a High Purity Valve for use in the Semiconductor marketplace.
Evans PLT Series Presslok® , is an innovative tube size press system for joining 304/316L tube for industrial air, inert gas, process cooling water, vacuum exhaust and other low pressure general service installations.
Pre-fab manifolds reduce the number of welds typically required by up to 65%.
Evans PW Series valves perform to the highest levels of leak integrity available on the market. All valves and valve assemblies are 100% helium leak tested to ensure reliability and low cost of ownership.
PW Series integrated design significantly reduces overall footprint, potential leak points and cost while improving quality in a compact, robust design. The Evans Bi-dicator (Pressure/Temperature) gauge eliminates the need for adding additional fittings and components for measuring pressure & temperature.

CFOS grade (cleaned for O2 service) integrated stainless 2-pc gas stick incorporates a ball valve, regulator, pressure gauge and 74-micron pre-filter.
CFOS grade (cleaned for O2 service) integrated 3-pc gas stick incorporates a ball valve, regulator, pressure gauge and optional 5-micron sintered filter/condensate trap.
90 Series mini ball valves are constructed with a low-cost cast body design, all sizes incorporate a “full bore” body and low torque design, valves are bagged in cleanroom, locking handles are optional.
80 Series mini 1-pc ball valves are constructed out of bar stock, unique injection molded TFM 1600 low dead space seat eliminates multiple seal points, requires higher torque to operate. Bagged in cleanroom.
30 Series mini 3-pc ball valves are constructed with an economical 304SS cast body design, all sizes incorporate a “full bore” body, locking lever style or butterfly handles are optional. Bagged in cleanroom.
Evans currently offers the widest range of sizes, end connections, and configurations of high purity ball valves on the market.
PW-HB Series hose barb fittings are manufactured with Push-lok style hose barbs (which requires no hose clamp) for ¼” thru 1” and king nipple style (hose clamp design) for 1-1/2” thru 2”.
R4I (Ready for Installation) Pre-fab manifolds are designed to meet all UHP cleanliness specifications. R4i laterals are fabricated using a pulled-tee method then welded, tested and packaged in a class 10 cleanroom environment. This method of fabrication reduces the number of welds typically required by over 65%. Cost, time pressure and lack of skilled labor combined with ever increasing demands on high quality gas systems call for new ways of cooperation. Drilling and collaring combined with proprietary welding technology reduces overall costs by over 30%.

FR Series 316SS “Fire Rated” 3-PC Ball Valves, API 607 approved. Valves come standard with upstream vented ball, cavity free RTFE seats, ISO actuator mounting pad, optional purge ports/valves. Cleaned/bagged in cleanroom.
The SV Series valves are designed with a “true bore” I.D. design. Stem seal is live loaded with bevel springs which compensates for stem wear. The SV valve provides leak tight vacuum shut-off to a helium leak rating of 1 x 10-8 scc/sec. All these design features along with secondary upper O-ring stem seal makes this valve ideal of vacuum applications.

Evans DM Series purge tools provide an economical, reliable, compact solution for manifolding UHP Argon purge gas. Manifold is machined out of solid block, eliminating multiple NPT/mechanical connections which reduces cost and eliminates potential leakage which can cause discoloration/contamination of the weld. All purge tools are helium leak tested to 1 x 10-9 scc/sec and guaranteed to a dry down rate of less than 10 ppb.

Evans DM Series purge station incorporates a purifier that provide P.O.U. purification of utility grade Nitrogen. Use of purified Nitrogen for blow down, line qualification and trickle purge save in excess of 10-times the cost when compared to using Argon.
Evans purge metering manifold design incorporates a one-piece all welded manifold eliminating additional mechanical connections thus making the assembly more robust and economical. Reduction of mechanical connections reduces the risk of leakage which can cause decolorization and contamination during welding/purge process.
