Evans Components, Inc. was the first to introduce a High Purity Valve for use in the Semiconductor marketplace.
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.
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.
SN Series valves are designed with a “true bore” port, cavity free PTFE seats, ISO 5211 mounting pad for air operation and live loaded stem packing are standard. The valves are ASME/BPE compliant and come with fractional & ISO size connections. Cleaned and bagged in cleanroom.
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.

PW Series regulator offers a lower cost, more compact design vs. PVC regulators currently offered on the market. The nickel-plated body is I.D. treated with Evans’ proprietary PWEA® wetted surface treatment that prevents stress corrosion cracking in aggressive water applications. (See Evans Technical Data Sheet for more information).
