Brass Check Valves Manufacturers

Brass check valves are designed to permit gas flow in one direction only. It directs the flow of inhaled and exhaled gases through the breathing system. During inhalation, pressure decreases in the mouthpiece chamber, which seats the exhalation check valve but opens the inhalation check valve. These are also used in a water well installation to keep the water from flowing back toward the pump when it is not pumping. These check valves can be provided with female pipe threads on both ends.
