3″ Threaded vapor valve

The aluminum 3.5” (89mm) pneumatically actuated interlock vapor valve is designed as a positive vapor recovery valve for use on DOT cargo tanks and is tested and certified to EN13082:2001 with markings per US DOT 49CFR§178.345-5(f). The sequential interlock design allows vapor valve to be plumbed in series with loading or unloading valve.  Air supply to “IN” port of vapor valve will only exit to “OUT” port after vapor valve has positively opened.  If an interlock feature is not required, outlet port can be plugged and valve will function as a basic non-interlock vapor valve.

The vapor valve features exceptional flow with an inward opening disk and a tapered seat to ensure a tight seal and prevent loss of lading due to surge or roll-over accident.  An aluminum body with FEP Teflon® main seal, fluorosilicone air cylinder seals, and stainless trim offers compatibility with a wide variety of products.**

Threaded mounting configuration installs in a 3.84” (98 mm) hole as provided by standard 16” offset manhole and is secured with a threaded mounting ring and set screws.  Air connections are 1/8” NPT.

The vapor valve meets shell strength test of 73 psig (5.0 bar).  Maximum operating pressure is defined as maximum tank pressure that valve can open against with given air-line pressure.

The maximum operating pressure of vapor valve is:
15 psi (1.0 bar) with 90 psi (6.2 bar) line pressure supplied.  *
20 psi (1.4 bar) with 120 psi (8.3 bar) line pressure supplied.*
