The CS800 Series direct-operated, spring-loaded regulators are available in numerous body sizes and end connections, outlet pressure settings, orifice sizes, and the option for internal or external pressure registration.
If the automated control system is operating, the pressure never gets high or low enough to cause the spring-loaded regulators to take over.
