Materials - 3065-S Mixers - Ordering Information
MATERIALS 3065-0 through -8 mixer bodies and mixing chambers are machined from iron castings. The -7 and -8 sizes have viton gaskets on flanged connections. Depending on the mixer size, gas cartridge assemblies are made from brass, steel and cast iron, with seals made from viton and nitril. Mixer displacement rods are made from steel. The rod support plugs are made from brass on -0 through -5 sizes and aluminum on -6 and larger sizes.
3065-S ASPIRATOR MIXERS
3065- -S Aprirator Mixers have oversized throats for higher air capacities and mixture pressures than standard mixers.
They are useful where:
— Burner capacity does not match a standard mixer size, e.g., certain line burner assemblies and special bore nozzles.
— Mixture line size is restricted, and the use of a standard mixer would prevent the combustion system from reaching full capacity.
On 3065-K models, steel or stainless steel is substituted for the brass parts (for use with gases corrosive to brass).
— A modest increase in combustion sytsem capcaity is desired without extensive re-piping.
3065-9 mixer bodies and mixing chambers are fabricated from steel, and assembled with a viton gasket. The 1122-7-F valve used on the 3065-9 for gas adjustment is made from cast iron, stainless steel, steel and has a viton seal.
Increasing mixer capacity in the 3065-S involves sacrificing suction efficiency, therefore it may be necessary to cross-connect the zero governor when using a -S mixer. When feeding several nozzles from one 3065- -S mixer, a mixture manifold at least one pipe size larger than the mixer outlet is recommended.
