Pilot-Operated Throttling Solenoid (SCADA) Valves
Uses Golden-AndersonÒ differential piston main valve.
Can be held in any throttled position by remote electrical signals to solenoid pilots.
Sizes 2½ to 42-inch (65 to 1,000 mm) in globe or angle body with ANSI, BS, DIN or ISO flanges.
Optional integral "stop-check" piston can prevent backflow in the event of pressure reversal.
Can be supplied with GA Industries Valve DirectorÒ to position valve by comparing 4-20 mA command and feedback signals.
Available in many variations to accommodate virtually any control scheme.
Function and Applications
Valve is held in throttled position by electrical signals to valve mounted solenoid pilots. Municipal and industrial uses include interfacing hydraulically operated valve with electronic positioning to control flow, pressure, level or other variables within a desired range.
