CONCOA 304 Series Regulator

CONCOA 304 Series Regulator

The CONCOA 304 Series is a three-port, chrome-plated brass, single-stage point-of-use regulator designed for high-purity, non-corrosive, or liquefied gases (up to grade 5.5). It provides secondary or final-line pressure control, reducing delivery pressure in a single step. Its durable construction and high-purity compatibility make it a cost-effective solution for applications that can tolerate minor outlet pressure fluctuations as cylinder supply decreases. Maximum inlet pressure is 3000 PSIG (210 BAR) or higher, depending on configuration.

Features:

  • 316L stainless steel diaphragm prevents inboard diffusion

  • CAPSULE® seat with 360° integral filtration

  • Low wetted surface area reduces purge requirements

  • Rear panel mount simplifies installation

  • Helium leak-tested for integrity

Specifications:

  • Max inlet pressure: 3000 PSIG (210 BAR)

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

  • Gauges: 2" (50 mm) plated case

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

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

  • Cv: 0.1; 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
