Quick Valve Dual-Channel Tray Valve - Flood Valve with Fast Drain Opening 1-2"

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

Detailed features

• Function: dual-channel (fill + drain); the drainage channel oxygenates the irrigation water during filling for better root development.
• Filling flow rate: ~9–40 l/min depending on pressure and the internal diameter of the opening; standard 4 mm, other diameters on request.
• Automatic drainage: ~28 l/min when water supply stops.
• Manual bottom valve: yes — lets you avoid filling a specific table/tray.
• Connections (options):
  • ¾″ hose
  • ½″ hose
  • PE 8×10.5 mm and 10×12.5 mm
  • PE 6×8 mm
• Installation: countertop hole Ø 27 mm for recessed fitting; can be installed beneath sump plastic filters.
• Durability: designed for years of use in a demanding production environment.

Recommendations for use

• Select the internal opening (mm) according to the available pressure to achieve the desired filling flow rate.
• Install the valve under a filter (sump) to prevent blockage by debris.
• When you need to shut off a particular table, use the manual bottom valve.

Summary – Benefits

• Fast filling with an adjustable flow rate based on opening size and pressure.
• Automatic drainage of ~28 l/min when 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.
