• Five output pressure ranges from 0-2 psi, 0-0.15 BAR, 0-15 kPa up to 2-100 psi, 0.1-7 BAR, 15-700 kPa • Compact size - excellent for applications where space is tight • Control sensitivity of 1/4" water column - high accuracy for use in precision applications • Pressure balanced supply valve allows the regulator to remain unaffected by supply pressure changes • Flow of up to 40 SCFM with 100 psig - for use in applications with high flow requirements • Aspirator tube design compensates downstream pressure drop under flow conditions • Separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing • Unit construction permits you service the Model 30 regulator without removing it from the line • 30222, 30232, 30242, 30252, 30223, 30233, 30243, 30253
