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 abrasive 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 dependability, 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.
