Model 4500A Pneumatic Volume Booster, 1:1 Ratio, 3/4” NPT, 1” WC Sensitivity, 0.5 psi Accuracy Features: • Flow capacity of 150 SCFM (255 m³/HR). • Five signal to output ratios meet most control element requirements. • Control sensitivity of 1" water column allows use in precision applications. • Large Supply and Exhaust Valves provide high forward and exhaust flows. • Soft Supply and Exhaust Valve seats minimize air consumption. • A balanced Supply Valve minimizes the effect of supply pressure variation. • An Aspirator Tube compensates down stream pressure droop under flow conditions. • A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing. • Optional remote feedback port minimizes pressure drop at final control element under flow conditions. • Optional Adjustable By-Pass Needle Valve option includes bubble tight exhaust valve allows tuning for optimum dynamic response (1:1 ratio only) and cycle free operation with valve positioners. • Unit construction lets service the Model 4500A without removing it from the line. • Canadian Registration Number (CRN) certification for all territories and provinces. • Hazardous Locations - Acceptable for use in Zones 1 and 2 for gas atmosphere; Groups IIA and IIB and Zones 21 and 22 for dust atmospheres. Benefits: • Extremely fast and responsive operation. • Versatility to meet most control element requirements. • Allows use in precision applications. • Minimizes air consumption. • Isolates the diaphragm from the main flow to eliminate hunting and buzzing. • Minimizes pressure drop at final control element under flow conditions. • Allows tuning for optimum dynamic response (1:1 ratio only) and cycle free operation with valve positioners • Certification for use in all Canadian territories and provinces.
