Quick Valve, two-channel valve for trays with quick drainage, 1 to 2 inches

Quick Valve – dual-channel tray valve

Quick Valve is the fastest and most commonly used valve for EBB & Flow trays from . It has two channels: one fills the tray, and the other drains it. When the water supply stops, the valve automatically drains at ~28 l/min. It is supplied as standard with a 4 mm internal opening (other diameters are available on request). Installation beneath the filters from is recommended to protect against leaves, soil, and debris.

Detailed specifications

• Function: dual-channel (filling + draining); the drainage channel enriches the irrigation water with oxygen during filling for improved root development.
• Filling flow rate: ~9–40 l/min, depending on pressure and the internal opening diameter; standard size is 4 mm, other diameters available on request.
• Automatic drainage: ~28 l/min when the water supply stops.
• Manual lower valve: yes — lets you prevent filling a specific table/tray.
• Connection options:
  • ¾″ hose
  • ½″ hose
  • PE 8×10,5 mm and 10×12,5 mm
  • PE 6×8 mm
• Installation: Ø 27 mm hole in the tabletop for fitting; can be installed beneath sumpplastic filters.
• Durability: designed for long-term use in a “rough” production environment.

Usage recommendations

• Choose the internal opening size (mm) according to the available pressure to achieve the desired filling flow rate.
• Install the valve beneath a filter (sump) to prevent blockage by debris.
• If you need to shut off a particular table, use the manual lower valve.

Summary – Benefits

• Fast filling with an adjustable flow rate based on the opening and pressure.
• Automatic drainage at ~28 l/min when the water supply stops.
• Improves irrigation water quality through oxygenation during filling.
• Flexible options for ½″, ¾″, and PE connections.
• Durable construction for a long service life in greenhouse conditions.

Installation and drainage

Compare the external dimensions with the installation space and check whether a drainage hole is already in place. Ebb & Flow systems require a compatible inlet, drain, reservoir, and cycle controller.
