Cla-Val Series 413 Valves are used to control above ground and underground storage tanks. This valve is available in a variety of configurations, sizes and materials.
Model 413-06 is a Combination Remote Control and Differential Valve equipped with pressure sensitive closing and rapid opening controls. The remote control operation is achieved using pressure in the pilot system. When pressure is applied to the cover of the reverse flow pilot valves, the main valve closes. When pressure is relieved from the cover of the pilot valves, the main valves opens.
The 413-06 is also equipped with a CDB7 Differential Control that responds to differential pressure changes across the main valve diaphragm.
