3/2 Coax Pneumatic Valve
3/2 way coax pneumatic valve range.
External air Namur mount pilot pneumatically actuated 3/2 way coaxial valves are supplied according to size, function, pressure, media and flow, and coax valve suppliers offers ranges of 3 port 2 position air driven coaxial valves to suit most applications, but the vast array of choice can sometimes lead to confusion. For example 3 way air operated coax valves are available with different port sizes from 1/4 through to 2" with various connections such as BSP- NPT - Flange PN16 PN40 PN100 PN200 etc, various orifice sizes offering different flow rates, a range of operating pressures, various materials of construction and a choice of elastomer and PTFE sealing options and valve functions to help provide the best cost effective solution to match the application at hand.
Below are example of the more popular 3/2 air actuated coaxial valves, all have options for normally closed or normally open. Stated maximum pressures shown are according to maximum inlet pressure however coaxial valve can handle back pressures at reduced rates typically 16 bar maximum.
