ISO 9001:2015 Certified - Nor-Cal Products, Inc dba Pfeiffer Vacuum Valves & Engineering is an ISO 9001:2015 certified company that has also received SSQA Preferred Supplier status from two large semiconductor equipment manufacturers. Our Quality Management System also supports MIL-Q-9858 and MIL-I45208 Quality Program Requirements and ANSI/ASQC C1 General Quality Program Requirements. Ongoing efforts are made to control and improve manufacturing processes. Periodic defect analysis results in process improvements with narrower acceptable limits on subsequent production runs. Our calibration procedures meet MIL-STD-45662A, and our QA sampling plan meets MIL-STD-105E. A coordinate measuring machine (CMM) is used for in-process and final mechanical inspections of vacuum chambers and other complex or close tolerance parts. CMM printouts of chamber final inspections can be furnished upon request.

ASME BPV U-Stamp Certified - Most vacuum chambers do not require an ASME code symbol stamp; however, having your vacuum chamber fabricated by a BPV certified company assures that the chamber will meet or exceed established standards. Stamped components are fabricated to the latest edition of the ASME BPV codes, which control chamber design, materials, fabrication, welder certification, test, and inspection. ASME certification is recognized in all 50 states in the U.S., all provinces of Canada, and an estimated 100 countries worldwide.
