Plastic Tube Fittings to Connect Air Signals

Inlet Check Valves (3000 psi working pressure)

Catalyst Injectors

Catalyst injectors are restrictive check valves which are often used to create back pressure on the catalyst side inlet

to the MD2 valve. Catalyst injectors are also used to balance pressures and flow on wide-ratio, low-viscosity catalyst

applications.

* Wide ratio applications 8:1 to 13:1 by volume.

** Injectors have a “snout” and must be screwed into a 1/4 npt(f) female coupling. Inlet is 1/4 npt(f).
