APOLLO VALVES -

4SG Series, Double Check Valve Assemblies
Apollo 4SG Series double-check valve assemblies are designed to prevent the backflow of contaminated water into the potable water supply system. They consist of two independently operating check valves (arranged in series), allowing double protection against backflow. These units have resilient seats to provide a bubble-tight seal between the valve body and the closure element (disc). They are made of high-quality materials for durability and corrosion resistance and have a grooved body for easy installation and maintenance. These double-check valves are ideal for use in commercial, industrial and municipal applications, such as water treatment plants, irrigation and fire sprinkler systems.
