CONCOA 411 Series Regulator

The CONCOA 206 Series is a four-port, chrome-plated forged brass, single-stage regulator designed for primary pressure control of gases from cryogenic liquid cylinders. While optimised for liquid cylinder flow, it is rated to 3000 PSIG (210 BAR) for safe use with high-pressure cylinders.

Features:

• 316L stainless steel diaphragm prevents inboard diffusion

• Large CAPSULE® seat allows higher flow rates than conventional regulators

• 3000 PSIG inlet rating ensures safe high-pressure use

• Standard relief valve protects diaphragm and gauges

• Helium leak-tested for integrity

Specifications:

• Max inlet pressure: 3000 PSIG (210 BAR)

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

• Gauge: 2½" (63 mm) plated case

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

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

• Diaphragm: 316L stainless steel; Cv: 0.28

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

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

• Compliance: Cleaned for oxygen service, PED 2014/68/EU, ANSI/ASME B40.1, CRN OH5216

Introducing the FSSCRRA Reverse Acting Rupture Discs – advanced compression or reverse discs featuring micro-scored calibrated sections that open in the form of petals. These discs are designed with 4, 6, or more radial scores, allowing for optimal opening and significantly reducing the risk of petal detachment. The FSSCRRA rupture discs are ideally suited for both high and low bursting pressures and can be safely utilised with gases and liquids (when a special gas cushion is present), even under cycling and pulsating conditions, without compromising safety margins. Reacting to excessive pressure within mere milliseconds, FSSCRRA rupture discs operate without fragmentation, making them particularly effective for the protection of safety valves. These rupture discs boast an impressive operating to bursting pressure ratio of up to 95% and demonstrate excellent corrosion resistance. This resistance can be further enhanced with a PTFE lining. Notably, FSSCRRA discs can operate under absolute vacuum conditions without requiring additional supports.

**Rhodes 913 Sight Glass with Integral Spout – Enhanced Viewing for Clear Liquids** The Rhodes 913 Sight Glass features an integral spout designed to create a jetting action that induces turbulent flow, significantly enhancing the visibility of clear liquids. Its generous viewing area enables easy observation of flow, colour, and condition, allowing for effective assessments of product quality and consistency. These indicators are versatile, suitable for both vertical and horizontal installation. The integrated spout also serves as a drip indicator, making it ideal for detecting valve leaks, distillation processes, or other similar conditions. With a range of materials available as standard, Rhodes Sight Glasses are proudly manufactured in the UK, utilising locally-sourced castings unlike many competitors who rely on components from overseas. **Product Specifications:** - **Sizes:** Available in dimensions from 1/2" to 4" - **Connections:** Flanged options available for most types - **Materials:** Constructed from a durable cast iron body, mild steel covers, and graphite gaskets - **Maximum System Pressure:** 16 Barg - **Operating Temperature Range:** -10°C to 180°C - **Compliance:** Fully compliant with the Pressure Equipment Directive (PED) and entirely manufactured within the UK. Optimise your process with the reliability and quality of Rhodes Sight Glasses – your trusted partner for transparent liquid management.
