DESCRIPTION

Eliminated under and overpressure application. To ensure accurate chemical application and avoids expensive chemical wastage. The accurate application also means improved productivity from workers.

OUTSTANDING FEATURES

OPERATE EXPLANATION

The Gate CFValve™ is designed to provide a constant rate of fluid flow at a pre-set pressure when coupled with a downstream orifice. Once the threshold operating pressure is reached, the fluid rate remains constant regardless of the input pressure. Should the input pressure fall below the threshold pressure, the CFValve™ will close and shut off the fluid flow. 

At rest, the Gate CFValve's™ diaphragm is held against the sealing ring, effectively closing the CFValve™. The fluid enters the inlet side of the CFValve™ and flows around the metering pin. The CFValve™ remains in the closed position until there is sufficient pressure to overcome the spring force. As the inlet pressure increases, the diaphragm retracts, moving the metering pin, which then throttles the fluid flow through the valve body. Under conditions where the input pressure varies, the spring modulates the diaphragm and pin assembly, reducing or increasing the input orifice area, thereby controlling the fluid flow.
