VAG GA Pressure Reducing and Sustaining Valve Figures 4700-D, 4700-U

VAG GA Industries Figures 4700-D and 4700-U self-contained, pilot-operated, differential piston actuated pressure reducing and sustaining valves reduce a higher, fluctuating inlet pressure to a lower, steady downstream pressure regardless of variations in demand, providing the inlet pressure is above a pre-determined minimum.

The valve will throttle as needed to sustain the minimum inlet pressure and close if the inlet pressure falls below the minimum.

The valve’s unique V-port trim provides a semi-linear flow characteristic for excellent control during periods of minimum demand plus full port capacity to handle peak demand such as fire flow.
