Automatic Control Valves
The Basic Valve
BTA 11

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 Self Actuating Type, Pilot Operated, Globe/Angle Pattern, Top & Bottom Guided, Glandless, Hydraulically Operated, Diaphragm Actuated for multifunction control Of less viscous, non corrosive, non abbrasive fluids.
• Our wide range Of control pilots makes it possible to Offer combination models for variety Of functions. The main valve contain only one moving part. This simplicity of design promotes dependibility, making the maintenance easier and extend the life of the valve.
• The lower portion of main valve diaphragm assembly is a mechanical check feature, which acts independently of diaphragm position or pilot control system, and provide immediate check action when flow ceases.

• The main valve consist only three major components; Body, Cover and the Top & Bottom Guided Diaphragm Assembly which is the only moving parts in the main valve making the online maintanence very easy.
• This valves are designed to control fluid flow at high pressure
• With simplicity of design & packless construction, minimal part wear is there which assure trouble free operation & long life of dependable.
• Actrol is available in various materials and in full range of sizes with flanged ends.

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.
