APOLLO Check Valve Stainless Steel

Install 2 inch boiler protection valve on twin boiler install… Very concerned about boilers condensing this valve works great in addition to a hydraulic separator. I’m very pleased with the valve.

Quality product, nicely assembled and timely delivery. Unbeatable price too! This switch exceeds in rating and will perform in many applications.

I have received my boiler at the date I have asked for and in perfect condition since it was properly packaged and protected.

Valve was easy to plumb in once I understood how it worked. Did not come with any kind of instructions, MBtek website has a diagram of how this worked. Basically, AB port goes to the boiler intake (mixed water), and the water exit (heated water) gets piped to B port this forms a loop until the mixing valve begins to open A port (cold water). This prevents the boiler from running to cold which can cause an acidic condensate from the pellets burning, which over time will eat your boiler from the inside out. Be sure to install this to protect your investment.

Im very pleased with my order. Everything arrived as promised very nice service.
