Altecnic / Caleffi 312 Series Safety Pressure Relief Valve 1/2" M x 15mm 4 Bar - 312405CST
The Altecnic / Caleffi 312 Safety Valve - 312405CST is essential for domestic hot water systems, providing vital protection for hot water cylinders and heating systems, including boilers and other components. This safety valve is meticulously selected for its specific set pressure. As system pressure increases, the valve activates once the discharge pressure is reached, releasing excess pressure into the atmosphere. This action safeguards both the boiler and hot water storage cylinder, ensuring safe operational conditions for personnel nearby.

FSGGRG - Graphite Rupture Discs
The FSGGRG Graphite Rupture Discs are replaceable and designed for mounting on either graphite holders (rated for pressures up to 10 bar g) or metal holders (up to 15 bar g). These highly versatile discs cater to a wide range of applications and are particularly efficient in handling aggressive fluids while exhibiting low sensitivity to temperature variations at bursting pressures. Constructed from ultra-pure graphite, the discs are impregnated with phenolic resins, which enhance their impermeability. When ruptured, they provide a complete opening while fragmenting into manageable pieces. For rupture pressures below 1.7 barg, vacuum support is necessary; however, these discs are self-supporting at higher pressure calibrations.
