Maximum Valve Leakage at Reseat: 25 c.c./min
Back pressure on the tank port (port 2) is directly
additive at a 1:1 ratio to valve setting
Reseat exceeds 85% of cracking pressure.
Hysteresis with dither < 4%
Hysteresis with DC input < 8%
Linearity with dither < 2%
Dither should be adjustable between 80-300Hz
(Recommended dither freguency 140Hz)
