Brass check valves are automatic, one-way valves designed to prevent backflow in plumbing, heating, and industrial systems. Constructed from brass, they offer durability, corrosion resistance, and are commonly used with water, oil, or air. These valves allow flow in one direction using a spring-loaded or swing mechanism. The temperature rating of the Brass Check Valve can go up to 400 degrees C, and they usually have a pressure rating of 6000 psi. The brass check valve has great impact resistance and it is generally installed close to the floor, next to the pump.
