Regulating valve for hose 4/6 mm, 2 pcs, AQUA DELLA

AQUA DELLA regulating valve set for 4/6 mm hose, two pieces, provides compact inline control for liquid or air flow in small-diameter tubing. Designed for 4/6 mm hose connections, the valves allow manual adjustment of flow and pressure in irrigation lines, aquariums, terrariums and other small distribution systems where precise control is required. Each set contains two inline valves made to be installed directly into flexible hoses for straightforward flow regulation without additional adapters.

Advantages

The inline design is compact and minimizes space requirements in tubing runs. Manual adjustment is intuitive and allows gradual regulation of flow rate and pressure. The valves are compatible with standard 4/6 mm flexible hoses and are supplied as a matched pair for multiple connection points or redundancy. Their simple construction supports easy installation and maintenance, reducing the need for specialized tools.

Suitable for

• Irrigation and drip systems with small-diameter hoses
• Aquarium and terrarium plumbing where flow tuning is needed
• Small pneumatic lines and air distribution in hobby systems
• DIY fluid distribution and laboratory models with 4/6 mm tubing

Key specifications

• Connection size: for 4/6 mm flexible hose
• Quantity: 2 pieces per set
• Operation: manual inline flow adjustment
• Compatible media: water and air (non-corrosive fluids)
• Mounting: inline insertion into hose without additional fittings

How to use

Cut the 4/6 mm hose at the desired control point, insert each valve end into the hose so that the hose fits securely over the valve barbs, and ensure a tight seating to prevent leaks. Adjust flow by turning the control mechanism until the desired rate or pressure is reached. For pneumatic applications, check for air-tight connections and for liquid applications verify there are no drips at the joint. Use one valve per line where localized adjustment is required; the second valve in the set can be installed on a different run or kept as a spare.

Usage recommendations

Use the valves with compatible 4/6 mm flexible hoses and avoid exposure to aggressive chemicals. For best performance, inspect hose connections periodically and replace the valve if signs of wear or leakage appear. When regulating flow for sensitive biological systems (aquariums, terrariums), make small incremental adjustments and monitor conditions after each change.
