Atomic M1 - regulator first stage

Monel components are used inside the first stage to increase strength, corrosion resistance and for oxygen compatibility. Grade 316 stainless steel, Zirconium-plated brass and Titanium make up the mechanism of the second stage. The M1 metering valve body is Zirconium/Nickel plated brass and the seat pressure limiter is stainless steel.

The valve body is made of stainless steel.
