About this file
This document is a detailed technical drawing for an 18" OD x 16" ID gate valve designed for ultra-high vacuum (UHV) systems, created by the Advanced Photon Source (APS) at Argonne National Laboratory. The drawing (B431-VC0001) specifies critical manufacturing requirements, including fabrication methods per APS Engineering Standard, precise dimensional tolerances (±0.5° angular, surface roughness specifications), and critical notes about vacuum component preparation. The stainless steel (304 SST) component features 36 equally spaced 3/8-24 UNF-2B threaded holes, a knife-edge sealing surface, and leak check grooves. Specific technical requirements include a vacuum leak check with a minimum sensitivity of 2x10-10 std cc/sec helium, protection of sealing surfaces during machining, and packaging with aluminum oil-free foil and plastic caps during shipment and storage.

NOTES:
1. THIS COMPONENT IS INTENDED FOR USE IN AN ULTRA HIGH
VACUUM (UHV) SYSTEM.
2. ALL FABRICATION METHODS MUST FOLLOW THE REQUIREMENTS
OUTLINED IN SECTION 2.1.3 OF ANL DOCUMENT APS
ENGINEERING STANDARD - VACUUM DESIGNS
(APS-PPR-VAC-000-A017-000128). ANY PROPOSED DEVIATION
FROM THESE REQUIREMENTS MUST BE APPROVED BY AES-MOM
VACUUM GROUP PRIOR TO IMPLEMENTATION.
3. PROTECT KNIFE-EDGE AND SEALING SURFACES DURING
MACHINING. ANY NICKS OR SCRATCHES TO A KNIFE-EDGE OR
SEALING SURFACE WILL RENDER THE PART UNACCEPTABLE.
4. PROTECT FLANGE WITH ALUMINUM OIL-FREE FOIL AND
PLASTIC CAPS DURING SHIPMENT AND STORAGE.
5. VACUUM LEAK CHECK SHOWS NO DETECTABLE LEAK WHEN
TESTING WITH LEAK DETECTOR WITH MINIMUM SENSITIVITY OF
2X10 -10
STD CC/SEC HELIUM PER APS_2018473.
