Sprung Disk Wafer Check Valve

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.

Resideo Braukmann SV300 Pilot Operated Safety Valve

The Resideo Braukmann SV300 Pilot Operated Safety Valve is expertly engineered to manage the medium flowing through it via an integrated pilot valve. This valve is ideally suited for installation in supply pipework branches, providing crucial protection for downstream components that could be compromised by excessive pressure, often arising from pump activities. When the inlet pressure reaches the pre-set opening pressure, the valve promptly transitions to the maximum flow position. Conversely, if the pressure decreases to the designated level, the valve gradually closes to mitigate pressure shock loads.
