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

Specifications:

• Max inlet pressure: 200 PSIG (14 BAR)

• Body: Chrome-plated forged brass; Bonnet: Chrome-plated die-cast zinc

• Gauges: 2½" (63 mm) steel with brass connections

• Seat: PTFE; Filter: 10-micron sintered bronze

• Temperature range: -40°F to 140°F (-40°C to 60°C)

• Cv: 0.02; Diaphragm: 316L stainless steel

• Helium leak integrity: 1 × 10⁻⁸ scc/sec

• Internal seals: PTFE; Ports: 1/4" FNPT

• Compliance: Meets/exceeds CGA G-4.1, PED 2014/68/EU, ANSI/ASME B40.1, CRN OH5216

The ARI STOBU Stop Valve, commonly referred to as a Crown Valve, is an essential component fitted to steam boilers, designed to effectively isolate the boiler steam from the associated processes or plant systems. Its name arises from its typical position at the top or "crown" of the boiler. The ARI STOBU Stop Valve is renowned for its reliability and performance in this crucial application.
