Pneumatic valve Identification...N with arrow, 1, 2,3...12 1

[hyperboneious]

I have to replace an air valve and the only data on the valve are the min and max pressure allowances and a symbol consisting of an "N" with an arrow crossing horizontally and facing towards the left. The numbers 1,2,3,4,...,11,12 surround the N with arrow in a circle....anyone have any idea what the N with arrow and numbers represent or if it's a manufacturer's logo??

Thanks,
Sadih

Could it be a date code? Indicateting the month/year?
Don't know, Boy how I love a mystery!

This is normal Port Identification used by all the manufacturers I am familiar with.

(1) is the INLET AIR SUPPLY, (2) is an out let to an actuator, (3) is the EXHAUST port and (4) is the other actuator port.

Normally a Pilot Operated valve will have Pilot Ports numbered (12) and (14). (12) Pilot Port shifts the valve to give flow (1) to (2) while (14) Pilot Port shifts the valve to give (1) to (4).

Any distributor should be able to get you a replacement with the info you have.
