NOTE: Pressure ratings were established under static pressure
conditions. Therefore, pressure ratings for any given flow, pressure
surge and/or vibration may vary from these ratings. Burst pressures
listed were taken at the point at which failure rendered the quick
disconnect inoperative. (Proof pressure equals 1-1/2 times the working
Cylindrical Pneumatic Valve pressure; burst pressure equals 2 times working pressure.)
