Medenus R50 Gas Pressure Regulator

Introducing the NABIC 500T Combined Pressure and Temperature Relief Valve, expertly designed for unvented hot water supply systems that require both temperature and pressure protection. This innovative valve ensures optimal safety by allowing the pressure and temperature mechanisms to operate independently, thus delivering dual protection within a single unit. With the NABIC 500T, you can have peace of mind, backed by our industry-leading 5-year guarantee. **Specifications:** - **Sizes Available:** - 3/4" (DN15) - 1" (DN20) - 1¼" (DN25) - 1½" (DN32) - 2" (DN40) - 2½" (DN50) - **Connections:** - Male BSPT (Taper) Inlet - Female BSPP (Parallel) Outlet - **Materials:** - Gunmetal Body - Viton Seat - **Set Pressure:** - 1.0 to 12.5 Barg (DN15 to DN25) - 0.4 to 12.5 Barg (DN32 to DN50) - **Maximum Temperature:** - 95°C (Factory set at 95°C, non-adjustable) **Important Note:** The DN value embossed on the valve body indicates the NABIC 500 valve body size used in its construction and does not correspond to the inlet or outlet size. For instance, a valve with 1" connections (DN25) is built using a DN20 NABIC 500 valve body, hence the designation of DN20 on the valve's side. Upgrade your hot water supply system with the reliable NABIC 500T Combined Pressure and Temperature Relief Valve and experience unparalleled safety and performance.

The Altecnic / Caleffi Relief Valve - Pushfit Inlet - 312007CST is an essential component for domestic hot water systems, designed to safeguard the hot water cylinder and protect heating systems, including boilers and other critical components. This relief valve is available in a selection of set pressures to meet your specific requirements. As system pressure increases and reaches the predetermined discharge pressure, the valve automatically opens, releasing excess pressure into the atmosphere. This function is crucial in preventing hazardous pressure levels that could endanger the boiler, the hot water storage cylinder, and any personnel nearby.
