ITT ENGINEERED VALVES
Dia-Flo® Direct Loaded Bonnet
An economical approach to automatic on-off operation for Dia-Flo weir type valves, ideal for multi-valve panel operation of batching systems and water and waste treatment systems. Special bonnets and diaphragms let the valve be operated by injecting air directly into the bonnet, pneumatic or hydraulic and with or without a pilot solenoid, with valve opening dependent on line pressure. Available 1/2" to 3" for pressures up to 100 psi and suitable for all standard weir body materials.
