600GD-16
Dual Chamber - Reduced Port
Series 600GD (Globe) and 600AD (Angle) are Ductile Iron, reduced port, dual chamber basic valves that incorporate a one-piece disc and diaphragm assembly. When pressure is applied to the upper diaphragm chamber and released from the lower diaphragm chamber, the valve travels to a closed position. When pressure is applied to the lower diaphragm chamber and released from the upper diaphragm chamber the valve travels to a full open position. When pressure is balanced between the upper and lower diaphragm chambers, the valve will hold an intermediate position until commanded to modulate open or closed by the pilot control system. The reduced port design offers improved low-flow performance and cavitation resistance.
Features
- Reduced port, dual chamber basic valve with a two-piece telescoping disc and diaphragm assembly
- Opens and closes in response to pressure on the upper and lower diaphragm chambers
- A mechanical check feature acts independent of diaphragm position or pilot control system, and provides immediate check action when flow ceases
- Reduced port design offers improved low-flow performance and cavitation resistance
