Technical Specifications Category Specification Type Volume Booster Relay, Force-Balance Input Signal 3 to 15 psig (0.2 to 1.0 bar) standard Output Signal 1:1 ratio of input, 3 to 15 psig Air Supply 20 psig (1.4 bar) minimum up to 100 psig (6.9 bar) maximum (depending on model and output pressure required) Flow Capacity Very high; significantly greater than a standard I/P converter or controller. Specific Cv (Flow Coefficient) values are available in detailed manuals (e.g., Cv ~ 1.4 for a 1/2" NPT model). Accuracy Typically within ±0.5% of output span (including linearity and hysteresis) Repeatability Typically ±0.1% of span Sensitivity Typically ±0.05% of span Connections 1/4" or 1/2" NPT (National Pipe Thread) female Body Material Cast Iron (standard, with corrosion protection), Ductile Iron, Aluminum Diaphragm Material Buna-N (standard)
