The PRD3-ANB-C-DEF miniature, twostage, diaphragm pressure regulator targets portable fuel cells, UAV aircraft, and instrumentation equipment.
Roughly the size of 10 stacked quarters, the regulator weighs about 23 gm in aluminum and 50 gm in brass and stainless steel. The PRD3 precisely controls output pressures from 0 to 20 psig. Maximum rated inlet-supply pressure is 500 psig. The regulator maintains a constant output even with wide swings in input pressure.
