Spirax Sarco DP27 Pilot Operated Pressure Reducing Valve (Flanged PN25)

The CONCOA 412 Series six-port, dual-stage cylinder regulator is designed for ultra-high purity inert gases, providing stable primary pressure control with minimal variation from cylinder depletion. Features include a metal-to-metal diaphragm seal, CAPSULE® seats with 360° filtration, cleanroom assembly, helium leak-checked integrity, captured vent bonnet, pipe-away relief, and front/rear panel mounting. Constructed from brass barstock body and bonnet, 316L stainless steel diaphragm, PCTFE/PTFE seats, 10-micron sintered bronze filter, 2 in brass gauges, Cv 0.1, 1/4 in FNPT ports, and PTFE internal seals. 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.

### Refrigeration Shut-Off Valves for Industrial Systems Refrigeration shut-off valves are essential components in industrial refrigeration systems, designed to isolate specific sections during maintenance, repair, or troubleshooting. These valves enable swift control of refrigerant flow, allowing particular parts of the system to be safely shut off without disrupting overall operation. They are commonly employed in refrigerant cycles, ensuring efficient and effective management of refrigerants. #### Product Specifications - **Sizes:** Ranging from 1/4" to 20" (varies by type) - **Connections:** Available with flanged, screwed, butt weld, and solder options (depending on the type) - **Materials:** Constructed from durable steel or stainless steel - **Medium:** Suitable for glycol-based cold brine refrigerants according to EN 378 p. 1, including NH3, R134a, R290 (propane), R507, and blends with refrigerant oil, as well as neutral, gas, and liquid media - **Set Pressure:** Options include PS 25, PS 40, PS 63, and PS 160 (varies by type) - **Temperature Range:** Capable of operating between -60 to +150 degrees Celsius These refrigeration shut-off valves are designed to maximise efficiency and safety in your industrial refrigeration setup. For optimal performance and reliability, choose the right valve type that aligns with your system requirements.
