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 fl anged 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.

On 3065-K models, steel or stainless steel is substituted for the 
brass parts (for use with gases corrosive to brass).

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.

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 do es 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.

— A modest increase in combustion sytsem capcaity is desired 
without extensive re-piping.

Increasing mixer capacity in the 3065-S involves sacrifi cing 
suction effi

  ciency, 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.
