Hattersley Fig 250W PN16 Double Check Valve

The CONCOA 302 Series is a four-port, chrome-plated brass, single-stage cylinder regulator designed for primary pressure control of high-purity, non-corrosive, or liquefied gases. Single-stage regulation is recommended for cylinders under 500 PSIG (34 BAR) or applications where minor outlet pressure fluctuations from cylinder depletion are acceptable, or where inlet pressure is stable.

Features:

• 316L stainless steel diaphragm prevents inboard diffusion

• CAPSULE® seat with 360° integral filtration

• Field-adjustable pressure limit for flexible applications

• Rear panel mounting simplifies installation

• Helium leak-tested for integrity

Specifications:

• Max inlet pressure: 3000 PSIG (210 BAR); optional 3500 PSIG (240 BAR) or 4500 PSIG (310 BAR)

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

• Gauges: 2" (50 mm) plated case

• Seats: PTFE; PCTFE for higher-pressure options

• 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, ANSI/ASME B40.1, PED 2014/68/EU, CRN OH5216
