Venturi injector tube with bypass valve for controlled fertilizer injection and easier adjustment of suction conditions.
Request Quote
Bypass valve for venturi injector kits, used to adjust flow and create the pressure difference needed for fertilizer draw.

Venturi injector tube that uses line pressure to draw liquid fertilizer into drip irrigation without electricity.

Water-driven proportional dosing injector for accurate fertilizer concentration control.

Pre-assembled venturi injector set with bypass valves and fittings for easy installation.

No-power venturi injector for precise fertigation in drip and sprinkler irrigation systems.
A fertigation system runs fertilizer through your existing irrigation lines. Water carries the nutrient solution directly to the root zone — no separate application step, no hand-mixing, no timing mismatch between watering and feeding.
The same injector can handle soluble fertilizers, wetting agents, pH adjusters, and some pesticide formulations, depending on the product type and dilution ratio. We manufacture venturi injectors and proportional injectors in-house and supply projects from small greenhouse operations to large field installations.
A fertigation injector sits on the mainline between your water source and the irrigation system. As water flows through, the injector draws concentrated fertilizer solution from a tank and mixes it into the flow at a set ratio — typically 1:100 to 1:500 depending on the injector type and crop requirement.
Venturi injectors work without electricity: the pressure differential across the venturi body creates suction that pulls the concentrate. Proportional injectors are water-driven and maintain a consistent dose ratio regardless of flow variation. Both types work with drip lines, drip tape, and micro sprinkler systems.
One thing worth knowing upfront: injector compatibility with your water pressure and flow rate matters. An injector sized for a 1″ mainline behaves differently on a 2″ line. If you're unsure which type fits your setup, send us your system specs.
Three injector types covering the main use cases — from a simple venturi body for custom integrations to a proportional injector for precise, flow-independent dosing on larger systems.
The wrong injector for the pressure and flow conditions is more common than it should be. These are the variables that actually determine whether the system works as expected.
