Niezgodka Type 80 Sustaining Valve

The CONCOA 401 Series six-port, chrome-plated brass barstock regulator provides single-stage primary pressure control for ultra-high purity inert, non-corrosive, or liquefied gases (up to grade 5.5). Ideal for applications tolerating minor outlet fluctuations or with constant/low inlet pressure (<500 PSIG/34 BAR), it is front-panel mountable and configurable with purge, low-pressure alarm, or multiple inlets. Key features include metal-to-metal diaphragm seal, CAPSULE® seat with 360° filtration, pipe-away relief valve, cleanroom assembly, captured vent bonnet, and helium leak-checked integrity. Specifications: max inlet 3000 PSIG (210 BAR) standard; body and bonnet chrome-plated brass; PTFE/PCTFE seats; 10 µm sintered bronze filter; 316L diaphragm; Cv 0.1; 1/4 in FNPT ports; 2 in gauges; temperature -40°F to 140°F (-40°C to 60°C). Conforms to CGA G-4.1, ANSI/ASME B40.1, PED 2014/68/EU, CRN OH5216.

The Altecnic / Caleffi 253 Solar Safety Valve - 253046 is designed to regulate pressure within the primary circuits of solar heating systems. This valve is specifically chosen based on the required set pressure. As pressure increases within the system, the valve activates when the discharge pressure is reached, releasing excess pressure to the atmosphere. This vital function helps prevent potential damage to solar collectors and other system components caused by excessive pressure levels.

### Product Description Gate valves are primarily utilised for on-off applications, providing reliable control over fluid and gas flow. These valves feature a robust construction, comprising a Body, Bonnet, Gate, Stem (with outside screw and yoke), a rising stem equipped with a non-rising handwheel, and an integral seat, with options available for renewable seats. Additionally, they incorporate an open and closed indicator along with a lockable handwheel for enhanced operational security. ### Features Gate valves are renowned for their ability to offer a positive shutoff with minimal pressure drop, making them highly effective for managing the flow of liquids and gases across various applications. With their sturdy design and straightforward maintenance, these valves are both efficient and user-friendly. Operable either manually or via automated devices such as motors, solenoids, or actuators, the gate valve functions effectively by acting as a barrier when closed, blocking fluid flow completely. When the gate is opened, it swings away from the seat, facilitating unrestricted flow through the valve. ### Materials - **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 Data #150 - **Design Standard:** MSS SP80 / BS 5154 / BS EN 12288 - **Size:** DN15 to DN100 - **Flanges:** ASME B16.5 #150 - **End To End:** ASME B16.10 #150 - **Testing:** EN 12266-1, API 598 - **Max Pressure:** 19 BAR / **Min Temperature:** -29°C - **Max Pressure:** 7.9 BAR / **Min Temperature:** 260°C - **Material Test Certification:** BS EN 10204-3.1 ### Technical Data #300 - **Design Standard:** MSS SP80 / BS 5154 / BS EN 12288 - **Size:** DN15 to DN80 - **Flanges:** ASME B16.5 #300 - **End To End:** ASME B16.10 #300 - **Testing:** EN 12266-1, API 598 - **Max Pressure:** 49.6 BAR / **Min Temperature:** -29°C - **Max Pressure:** 20.6 BAR / **Min Temperature:** 260°C - **Material Test Certification:** BS EN 10204-3.1 Enhance your industrial operations with our high-performance gate valves, ensuring safe and effective control over your fluid and gas systems.
