VAG GA Surge Relief Valve Figures 6600-D, 6600-U, 6700-D, 6700-U for Water

VAG GA Industries Figures 6600-D, 6600-U, 6700-D and 6700-U self-contained, pilot-operated, differential piston actuated surge relief valves protect water systems from excessively high pressure due to a sudden stoppage of pumping or valve closure.

The valves are closed as long as the pressure at its inlet is below the pilot setting but open as quickly as needed to discharge water out of the system at the rate necessary to prevent a further rise in pressure. The valve closes slowly and seals tightly when pressure decreases below the pilot setting.

The valve’s unique V-port trim ensures stable operation under all conditions and its full port design provides maximum relief capacity.
