3 1/2" Aluminum Vapor Valve
Sequential Interlock
Available in two configurations - bolted design mounts in 20" offset PAF manhole cover using eight 3/8-16UNC bolts (included), while threaded design mounts in 16" offset PAF manhole. Both versions meet all requirements for loading/unloading venting devices on MC306 and DOT406 cargo tanks and are tested and marked with a test pressure of 36 psig in accordance with 49CFR178.345-5(f).
Inward opening action prevents loss of lading due to surge pressure during a roll-over accident. All moving parts are internal to minimize chance of freeze-ups during cold weather. Aluminum bodies with stainless trim minimize corrosion and PTFE seals in contact with vapors ensure compatibility with a wide variety of products.
Service Temperature Ratings (ºF)
Standard Valves -20 ºF to 200 ºF
w/ '023' suffix (fluorosilicone) -80 ºF to 400 ºF
Note: Temperature ratings are based on published information and may vary due to actual conditions.
