The CONCOA 422 Series six-port, single-stage regulator provides primary pressure control for ultra-high purity, corrosive, and toxic gases. Ideal for cylinders under 500 PSIG (34 BAR) or applications tolerating minor outlet pressure fluctuations, it can be configured as a single station manifold with purge, low-pressure alarm, or multiple inlets. Features include metal-to-metal diaphragm seal, CAPSULE® seats with 360° filtration, pipe-away relief, cleanroom assembly, helium leak-checked integrity, captured vent bonnet, and front/rear panel mounting. Constructed from 316L stainless steel body, chrome-plated brass bonnet, PTFE/PCTFE seats, 316L diaphragm, 10-micron stainless steel filter, Cv 0.1, 2 in stainless gauges, PTFE seals, 1/4 in FNPT ports. Rated up to 3000 PSIG (3500 or 4500 PSIG optional), temperature range -40°F to 140°F (-40°C to 60°C). Conforms to CGA G-4.1, ANSI/ASME B40.1, PED 2014/68/EU, and CRN OH5216.

**Gate Valves - Reliable Solutions for On-Off Services** Gate valves are expertly engineered for efficient on-off service applications. Comprising a robust Body, Bonnet, Gate, externally threaded Stem, and a Yoke with a rising Stem that features a Non-Rising Handwheel, these valves offer exceptional functionality. They come equipped with an integral seat as standard, with options available for renewable seats, as well as an open and closed indicator complete with a lockable handwheel. **Key Features of Gate Valves** Gate valves provide a positive shutoff mechanism with minimal pressure drop, making them ideally suited for regulating the flow of liquids or gases across diverse applications. Their durable construction and straightforward design also enhance maintenance ease, ensuring long-term reliability and performance. These valves can be operated either manually or through automated systems such as motors, solenoids, and actuators. When the gate is closed, it completely obstructs flow, while opening the gate permits unrestricted fluid passage, ensuring effective control over fluid dynamics. **Material Specifications** - **Body/Bonnet:** NAB (ASTM B148 C95800) - **Stem:** NAB (ASTM B150 C63200) / MONEL (ASTM B865 N05500) - **Bonnet Joint:** SS-136 + Graphite - **Handwheel:** ASTM A351 CF8M **Technical Specifications for #150 Series** - **Design Standard:** API 600 / ISO 10434 / BS 1414 - **Size Range:** DN50 to DN600 - **Flanges:** ASME B16.5 #150 - **End to End Dimensions:** ASME B16.10 #150 - **Testing Standards:** EN 12266-1, API 598 - **Maximum Pressure:** 19 BAR - **Minimum Temperature:** -29°C - **Maximum Pressure at Higher Temperature:** 7.9 BAR - **Maximum Operating Temperature:** 260°C - **Material Test Certification:** BS EN 10204-3.1 **Technical Specifications for #300 Series** - **Design Standard:** API 600 / ISO 10434 / BS 1414 - **Size Range:** DN50 to DN600 - **Flanges:** ASME B16.5 #300 - **End to End Dimensions:** ASME B16.10 #300 - **Testing Standards:** EN 12266-1, API 598 - **Maximum Pressure:** 49.6 BAR - **Minimum Temperature:** -29°C - **Maximum Pressure at Higher Temperature:** 20.6 BAR - **Maximum Operating Temperature:** 260°C - **Material Test Certification:** BS EN 10204-3.1 **Why Choose Our Gate Valves?** Opt for our gate valves for their unmatched reliability and ease of maintenance.
