CARTEN - FUJIKIN INC

What CARTEN - FUJIKIN INC does

Carten-Fujikin, Inc. is a Connecticut-headquartered manufacturer of ultra-high purity (UHP) bellows and diaphragm valves serving the global semiconductor industry. Founded in 1970 in Danbury, CT, and acquired by Japanese parent Fujikin Inc. in 1990 (with the legal name updated to Carten-Fujikin, Inc. in 2015), the company operates two manufacturing facilities: a 66,000 sq ft state-of-the-art plant in Cheshire, Connecticut (relocated 1996), and a 33,000 sq ft European operations facility in Waterford, Ireland (established 1980, expanded 1999). The product portfolio spans stainless steel bellows valves (HB, GBV, HBA, GBA, HF, HFA, HFLD, HFC, HFCP, HFCA series), stainless and duplex diaphragm valves (SPDS, DCS, MD/MDC, DPC, UPC series), check valves, vacuum generators, and an emerging ceramic valve line (CBV, CHL HiLife, AD, AR2000 series) using 99.5% alumina ceramic. Flagship technical claims include the HFCP 8-inch bellows valve at 2027 Cv (highest Cv in the semiconductor industry), HFLD at up to 1917 Cv with 10 Ra surface finish and Inconel 625 bellows, and AD ceramic linear valves with sub-0.2% backlash and 0.1 second response time.

Carten-Fujikin also fabricates integrated gas systems through its R4i prefab lateral program, partnering with Dockweiler to produce pre-assembled lateral-and-valve systems up to 24 feet in length, 100% Helium leak tested at 1x10-9 scc/sec in a Class 10 cleanroom environment. These integrated systems are installed in current-generation semiconductor process tools, positioning the company as a subsystem supplier to fabs and process tool OEMs in addition to its component-level business. Customers are concentrated entirely in the semiconductor vertical, including fabs, gas cabinet manufacturers, and process tool OEMs requiring containment, cleanliness, corrosion resistance, and high flow capacity for UHP gas and chemical distribution.

The company sells through a hybrid model: direct enterprise field sales via regional managers (Steve McManus for the West Coast, Jorge Paz for the East Coast, Harry Sherwood for the Western region) combined with an extensive global independent distributor network covering 30+ countries across North America, Europe, the Middle East, Asia Pacific, South Asia, South America, and Africa. Pricing is quote-based rather than list, with no public disclosure of unit pricing. Carten-Fujikin is ISO 9001:2015 certified by NQA (issued 2021-08-13), is privately held as a wholly-owned subsidiary of Fujikin Inc., and has no public funding, revenue, or headcount disclosures.
