Quick Action Valve Pack of 20. 13mm, 19mm, and 25mm Hydroponic Inline Flow Control Valves

Quick Action Valves are a inline irrigation shut-off and flow control valves designed for fast, precise control of water and nutrient delivery in hydroponic systems. Available in 13mm, 19mm, and 25mm, each size is supplied in packs of 20, making them ideal for complete system builds, multi-line irrigation setups, and commercial-scale installations.

Engineered for reliable sealing and low flow restriction, these valves allow growers to instantly isolate, regulate, or balance irrigation zones, improving overall system efficiency and control across all hydroponic configurations.

Available Sizes (Sold in Packs of 20)

13mm Quick Action Valve. Micro irrigation, drip lines, and small hydroponic setups.
19mm Quick Action Valve. Medium irrigation lines, reservoir feeds, and zone control applications.
25mm Quick Action Valve. High-flow mainlines, commercial irrigation systems, and large reservoir management.

Key Benefits

Fast Action On/Off Control. Instant flow adjustment for irrigation management, maintenance, and zone isolation.
Three Size Options (13mm, 19mm, 25mm). Covers the full range of hydroponic tubing and irrigation line diameters.
Pack of 20 Units. Bulk format supports complete system builds and commercial-scale installations without reordering.
Low Flow Restriction Design. Maintains system pressure efficiency when valves are open.
Hydroponic-Grade Plastic Construction. Nutrient and corrosion resistant for long-term use in recirculating systems.
Inline Installation. Easy integration into existing irrigation lines without system redesign.
Leak-Resistant Sealing. Reliable long-term operation across continuous wet environments.
Reusable and Serviceable. Cost-effective for system expansion and ongoing maintenance.

How It Works

Quick Action Valves optimise three core irrigation control functions. Flow regulation: enables precise water and nutrient delivery control at each irrigation zone or plant site. System zoning: allows individual line isolation and balancing without shutting down the entire system. Operational efficiency: rapid maintenance access reduces system downtime and simplifies troubleshooting across large multi-site installations.

The result is more efficient irrigation, improved plant consistency, and a scalable system design that can be expanded or modified without full system shutdown.

Why Inline Flow Control Improves Hydroponic Performance

No Zone Isolation in Irrigation Systems. Quick shut-off enables instant section control and maintenance flexibility without disrupting the full system.
Uneven Nutrient Distribution. Flow balancing across lines improves consistent nutrient delivery to all plant sites.
System Downtime During Maintenance. Isolate individual lines without shutting down the entire irrigation system.
Excess Water Use or Runoff. Controlled flow reduces waste and improves overall irrigation efficiency.

Advanced Application: Dutch Bucket Medium Reset

Installing a quick action valve at the drain outlet of a Dutch bucket system unlocks a highly effective medium reset technique. By closing the valve during a large flush, the nutrient solution is held in the bucket, fully saturating the medium from the bottom up. Once the medium is completely saturated, open the valve and the solution drains freely, carrying accumulated salts, old nutrient residue, and compaction with it. This process resets the substrate to a clean, evenly hydrated state, restoring hydraulic conductivity and nutrient uptake efficiency without removing or replacing the medium. It is one of the most practical maintenance techniques available for coco and perlite-based Dutch bucket systems.

What Sets It Apart

Most growers underestimate the value of inline flow control until they need to isolate a line mid-cycle or balance uneven irrigation across a multi-site system. The pack of 20 format means a complete drip system can be fully valved at every outlet without multiple orders. The three size options cover every standard hydroponic tubing diameter, from 13mm drip lines through to 25mm commercial mainlines. For Dutch bucket growers specifically, the drain valve technique described above is a low-cost, high-impact maintenance tool that extends medium life and maintains consistent substrate performance across long grow cycles.

Frequently Asked Questions

What size fittings do I need for Quick Action Valve Pack of 20?

Hydroponic irrigation fittings are sized by internal diameter — common sizes are 4mm, 13mm (½"), 19mm (¾"), and 25mm (1"). Match fittings to your existing tubing or pump outlet diameter. When in doubt, 13mm is the most common size for standard hydroponic systems and is compatible with most pumps and mainline tubing in the 300–2000 L/hr flow rate range.

How do I prevent leaks with Quick Action Valve Pack of 20?

Push-fit barbed fittings should be inserted firmly until they bottom out against the shoulder. Soft poly tubing grips barbs securely without clamps for most low-pressure applications. For higher-pressure or constant-run systems, add hose clamps over the barb connection for a leak-free seal. Always pressure-test your system for 30 minutes before introducing plants.

Does Quick Action Valve Pack of 20 ship fast within Australia?

Yes — Quick Action Valve Pack of 20 ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
