CONCOA 483 Series Regulator

CONCOA 483 Series Regulator

Four-Port, Brass Barstock, High Flow Pipeline Regulator for High Purity Inert Gas Applications

The CONCOA 483 Series regulator is designed for high flow inert gas applications, including bulk gas distribution, high purity chamber pressurization, and liquefied hydrocarbon analysis. Its internal pressure equalization minimizes delivery pressure variations typical in pipeline systems. Rated to full cylinder pressure, the 483 Series ensures safe operation even in the event of primary pressure control failure.

NABIC 500T Combined Pressure & Temperature Relief Valve

NABIC 500T Combined Pressure & Temperature Relief 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.
