Mini Valves and Fittings for Drip (Blind) Tubing: Professional Solutions at Agras

The reliability of a long-term irrigation system depends on the quality of every single joint. While drip tape is often chosen for seasonal crops, drip and blind tubing is the solution for years of operation. Consequently, the hardware for such systems must withstand significantly higher loads. At the Agras online store, you will find a professional range of mini valves, barbed fittings, hold-down stakes, and seals that ensure the flawless performance of your irrigation in gardens, greenhouses, or open fields.

Stability and Fixation: The Role of Hold-Down Stakes

When installing a perennial drip irrigation system over long distances, thermal expansion and water pressure can cause the mainline and drip pipes to shift significantly. To prevent chaotic movement across the field or greenhouse, a drip tubing hold-down stake (drip line peg) is used.

This holder allows you to securely fix a 16 mm or 20 mm tube in a pre-set position. This ensures that every emitter delivers moisture precisely to the plant's root zone. Our catalog features standard stakes as well as reinforced models from the Irritec brand, known for their high-strength plastic and resistance to shifting in loose soil.

Mini Valves and Connectors for System Upgrades

Specialized mini valves are used to manage water flows within the network. Unlike tape fittings, tubing valves feature "barbed" connections, which provide a tight fit against the inner wall of the tube.

Key Valve Types in the Agras Range:

• Starter Valve with Grommet: Ideal for tapping into a rigid PE mainline. Used in conjunction with a rubber seal for total watertightness.

• Valve with Lock Nut: Features an additional tightening nut that clamps the tube, preventing it from popping off even under pressures exceeding 3 bar.

• Coupling Valve (Tube-to-Tube): Allows for connecting two segments of tubing with the ability to independently shut off specific sections.

• Tape-to-Tube Converter Valve: A unique solution for transitioning from a mainline tube to a seasonal drip tape.

In case of accidental damage, a straight connector (mender) becomes an indispensable tool. This simple yet reliable device allows for quick restoration of the line. Additionally, tees and elbows are available for system branching and maneuvering around obstacles.

Leak-Proofing and Seals: Proper Tapping Technology

To ensure the system operates efficiently without pressure loss, pay close attention to the mainline connection points. The rubber grommet for drip irrigation is a small but critical component used to seal mini valves, starters, and threaded fittings.

The installation process is simple:

• Drill a hole in the mainline pipe with a diameter matching the grommet's outer diameter.

• Insert the seal into the hole.

• Push the fitting or valve into the seal with firm pressure.

Due to the material's elasticity, this connection withstands temperature fluctuations and vibrations, preventing leaks throughout its lifespan.

End Caps and Termination Fittings

Every irrigation line requires a reliable seal at its termination point. Professional systems utilize a tube end cap or the popular "Figure-8" end plug. The Figure-8 design is particularly practical, as it allows for quick system flushing—simply slide the ring off and straighten the tube end. For more complex technical setups, flange-mounted plugs are used, where the upper pin serves as a pivot axis for easy maintenance.
