Refrigeration Shut-Off Valves

### 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.

Altecnic / Caleffi 311 Series Safety Relief Valve 1/2" x 1/2" F x F 8 Bar - 311480 Altecnic / Caleffi 311 Series Safety Relief Valve 1/2" x 1/2" F x F 8 Bar - 311480

The Altecnic / Caleffi 311 Safety Valve - 311480 are used in domestic hot water systems to protect the hot water cylinder and in heating systems to protect boiler and other components. The valve is selected for the required set pressure. As the pressure rises, when the discharge pressure is reached the valve opens and discharges to atmosphere, preventing the pressure within the system reaching levels which would be dangerous for the boiler, hot water storage cylinder and any personnel in the adjacent vicinity.
