CONCOA 203 Series Regulator
The CONCOA 203 Series is a chrome-plated forged brass, single-stage regulator designed for low-pressure delivery of non-corrosive, liquefied, or high-purity inert gases (up to grade 4.5). It provides precise final pressure control from low inlet pressures, with adjustable delivery as low as 0.1 PSIG (7 mBAR) in 0.05 PSIG (4 mBAR) increments, ideal for applications requiring atmospheric or sub-5 PSIG (350 mBAR) outputs.
Features:
Fine-adjusting screw for precise pressure control
316L stainless steel diaphragm prevents inboard diffusion
CAPSULE® seat design with 360° integral filtration
Helium leak-tested for integrity
