The Automatic Control Valve, the word is self explanatory. It is a highly engineered Automatic Control Valve knowledgeably designed to operate of the line pressure or if desired, from an independent power source. Actrol valves are hydraulically operated, diaphragm actuated for multi-function control of non corrosive, non abrasive fluids.
The main valve is normally closed, when pressure is applied to the valve inlet the same pressure is applied to the cover also (upper chamber) the valve remains close. By controlling the pressure in the cover the valve can be made fully Open or closed.
When pressure in the cover chamber is released to a lower pressure zone the line pressure at the valve inlet opens the valve allowing full flow.
When the pressure from the valve inlet is applied to the cover chamber, the valve closes drip tight.
Actrol valves are hydraulically operated ,by introducing or releasing the liquid from above the diaphragm at controlled rates. A pressure differential is required , either inlet to outlet or inlet to atmosphere, depending on application.
The control valve holds any intermediate position when operating pressures are equal above and below the diaphragm. The control pilot modulates the valve to automatically compensate for line pressure changes.
