Altecnic / Caleffi 311 Series Safety Relief Valve 1/2" x 1/2" F x F 6 Bar - 311460

The Altecnic / Caleffi 313 Relief Valve with Gauge (Product Code: 313560) is an essential component for domestic hot water systems and heating setups. Designed to safeguard hot water cylinders and boilers, this valve is tailored to ensure optimal safety by releasing excess pressure. Upon reaching the designated discharge pressure, the valve automatically opens, venting to the atmosphere and preventing hazardous pressure levels that could jeopardise the boiler, hot water storage cylinder, and nearby personnel. This model is supplied complete with a built-in pressure gauge for added convenience and monitoring.

The FSLPDDW Double Way Rupture Discs are sophisticated composite conventional discs constructed from four key components: a slotted, perforated metal section, a sealing membrane (typically made from PTFE, but also available in various metallic and non-metallic materials), a protective section, and a calibration ring. Designed to be installed between flanges, these discs are ideal for use with gases and liquids in static conditions, particularly at low pressures. The FSDIFDW discs promptly react to excessive pressure, achieving complete opening within milliseconds, making them an excellent choice for valve protection. Vacuum or counter-pressure support options are also available. Additionally, composite rupture discs offer simultaneous protection from both pressure and vacuum.
