If you look closely at what Van's provided with the RV-14 kits, you will see that the closure and mounting hinge is S.S. The box is alum. but in case of a fire the SCAT tubing will burn off anyway, so what if the box goes with it if the flapper keeps the hole plugged.

Ron,

I looked closely at the heater valve today and you are absolutely correct. the flapper itself is SS. You just saved me a couple of hundred dollars. That will pay my VAF dues for quite a while! Should have known that the Van's engineers are smarter than me.

Brent

Don't forget Brent that there are different rivets called out for that flap also.

Default Got a part #?

What is the part # for this al/ss heater box? Is it the same as used on the 7's? Updated or option? Admittedly I'm not current on the research for this but it's on my soon "to do / buy" list.

Systems are only as good as their weakest link.

The box referenced above will require (as previously noted) stainless or monel rivets. A stainless flapper won't do you much good if it falls off the firewall after the rivets melt.

Personally I'd rather see a flapper with the cable control on the inside of the firewall. Same reason; the stainless flapper won't work unless held firmly closed, and a red hot Bowden cable in compression probably won't get 'er done. It would be iffy even if the hot cable was in tension.

Default This one--heater bypass valve

http://www.planeinnovations.com/prod...-valve-hbv-02/
With cabin side control lever for RV-7, RV-8 and RV-9.

The cabin side control unit is commonly used on RV7, RV8 and RV9 aircraft where the air is distributed in the cabin through a plenum.

All stainless steel construction offers a fireproof closure in case of an engine fire.

Designed with weight in mind, our stainless unit weighs 3.95 ounces and replaces the TG-10 aluminum box that weighs 3.28 ounces.

New flapper design offers better seal to keep out hot air when closed.
Born from necessity and designed with a passion for flight, the products offered by Plane Innovations LLC were thought out by builders looking for better solutions and thoroughly tested prior to release for sale.

The designs of these products have been directed at safety concerns, longevity and convenience.
Our products offer superior functionality for the experimental aircraft builder/owner.
-------------------------
I recently updated my firewall and installed two of these. Well built, all SS and actuator arm on the inside like my original.
FYI..2 inch hose and mounted with AN bolts (this was a RV-14 thread I jumped into with RV-6 experience)
