NOTE: “G” Marked prior to the valve number denotes Gang Feeding.
“E” Marked prior to the valve number denotes Explosion Proof.
“H” Marked prior to the valve number denotes High Pressure Valve. “F” Marked prior to the valve number denotes Filter Valve.
Where numerous options are specified, valves will be marked with 2 numbers to identify valve series and type, followed by specifically assigned numbers.
* For 3 way valves this number will consist of two suffix letters. The first indicates the inlet orifice & the second the exhaust orifice. ** For valves with a combination of two standard body options, this suffix will consist of two letters.
**** In Series 70 -1/16 - 5/16 Orifice.
† For series H high pressure valves only.
†† 2 in Series 15 is 1/8 NPT Aluminum only.
††† Letter K followed by “M” in 7th digit column indicates molded spade terminal coil & yoke.
