CONCOA 455 Series Regulator

CONCOA 455 Series Regulator

Four-port, electroless nickel-plated forged brass, single-stage regulator for highly corrosive gases

The CONCOA 455 Series regulator is designed for primary pressure control of highly corrosive gases such as chlorides, sulfides, and other acid-forming gases. It features a Dursan®-coated capsule and diaphragm, providing superior corrosion resistance compared to 316L stainless steel or exotic metals like Hastelloy®. For fluorine service, a passivated stainless steel CAPSULE® and diaphragm create a fully resistant assembly. Deep purge assemblies are recommended to prevent moisture from forming acids in the gas stream.

Features:

  • Dursan® internals for enhanced corrosion resistance

  • CAPSULE® seat with 360° integral filtration

  • Captured vent protects against diaphragm failure

  • Spectrometric helium leak-checked for integrity

Specifications:

  • Max inlet pressure: 3000 PSIG (210 BAR)

  • Body/Bonnet: Electroless nickel-plated forged brass

  • Gauges: 2½ in (63 mm) Monel®

  • Seat: PTFE

  • Nozzle: 316L stainless steel (passivated) or Dursan® (non-passivated)

  • Filter: 10-micron stainless steel or Dursan® mesh

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

  • Diaphragm: 316L stainless steel (passivated) or Dursan® (non-passivated)

  • Cv: 0.2

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

  • Ports: 1/4 in FNPT

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

Altecnic / Caleffi 312 Series Safety Relief Valve 1/2

Altecnic / Caleffi 312 Series Safety Relief Valve 1/2" x 1/2" M x F 2.5 Bar - 312425

The Altecnic / Caleffi 312 Safety Valve - 312425 is an essential component for domestic hot water systems, designed to safeguard hot water cylinders and heating systems, including boilers and other critical components. This safety valve is chosen based on the specific set pressure required for your system. As pressure increases and reaches the predetermined discharge pressure, the valve opens, allowing excess pressure to escape to the atmosphere. This vital function prevents the internal pressure from escalating to levels that could pose a risk to the boiler, hot water storage cylinder, and the safety of personnel nearby.
