500mm CheckMate Valve on Keelings Fruit Farm
Low headloss, low maintenance check valve solution
A 500mm CheckMate non-return valve installed in 2010 keeps rainwater separate from irrigation water yet allows rainwater to fill the irrigation ponds.
Design: Direct by owner
Keelings fruit farm is an international supplier of soft fruit from a farm near Dublin Airport. This 100% family owned Irish company has been growing fruits and salads and supplying them to local Dublin markets since the 1930s.
The 26 Ha of glass roofs for the farm greenhouses need to be cleaned every two weeks... and not just with any water. Soft rainwater is best, as treated water will leave limescale deposits. The rainwater is collected from the roof and stored in ponds, to be used for cleaning the glass as well as supplementing the potable water supply used for irrigation.
A 500mm CheckMate non-return valve installed in 2010 keeps the rainwater separate from the irrigation water, yet allows rainwater to fill the irrigation ponds. The CheckMate check valve's rubber design means that it is not subject to corrosion and thus has a long service life.
