Venturi Injector Suction Control Valve

Control the fertilizer intake

This manual control valve fits the suction side of a compatible Venturi fertilizer injector. The handle allows the operator to adjust the solution intake or close the suction connection. It is useful when building or maintaining a fertilizer feeding branch and the existing valve needs replacement.

A valve for the suction connection

The pictured component has a manual handle and connection fittings for the injector intake arrangement. It is a separate valve component. Agree the supplied connection configuration before ordering, particularly when matching an existing injector. A valve used to control fertilizer intake has a different role from a mainline valve used to establish a pressure difference.

Match it to the injector and feed line

Compare the injector suction port, valve ends and solution tubing connection. Confirm thread type, size, sealing method and pressure suitability for the installation. The connection must remain secure while the injector is operating, and the valve and seals must be compatible with the fertilizer solution.

Set the intake under working conditions

Establish water flow through the injector before adjusting the intake valve. Open it gradually and check that the solution is being drawn from the container. Measure consumption over a timed interval to establish the actual draw rate. A handle position alone does not establish the delivered fertilizer concentration.

Maintain the feeding branch

Close the intake when feeding is complete and follow the system flushing procedure. Isolate and depressurize the equipment before removing the valve. Inspect connection seals and keep the intake path free from fertilizer deposits. Confirm whether tubing, strainers and other accessories are required separately.
