ValkScreenVision
The new vision of screening
The new vision of screening
Van der Valk Horti Systems is introducing a new screen insertion system. It saves time when inserting or replacing screen cloths and is less risky for both crop and installer. As the screen cloth is inserted directly into the profile, there is no need to use clips. As a result hardly any work is required amongst the crop nor at great heights.
As well as being quick, clean and safe, the system is also flexible. It is suitable for every type of screen and can be obtained from a large group of installers.

Outside screen system
Outside screen system
Greenhouse climates can be controlled better if certain weather
factors can be ‘screened out’ outside the greenhouse. Excluding sunlight
reduces solar radiation and lowers the temperature, which is especially
important for high-quality ornamental plants like orchids and roses.
Outside screening also means electricity savings (due to a decreased
demand for cooling) and higher CO2 concentrations (less loss through
ventilation). And thanks to its insulating effect, there are significant
energy savings in the s

2SaveEnergy® is a new, practical and economical solution for energy-ef cient growers.
This all-purpose greenhouse covering contains an outer layer of transparent glass with
a double anti-re ective coating and an under layer of extremely durable, diffuse
F-CLEAN lm. In between there is a cavity that can be ventilated.
This combination has similar insulation properties as multi-coated double
glazing, but in a format that is lighter and easier to use. Above all, it allows

Slide System
Slide System
The KliMax Compact slide system from Van der Valk Horti Systems has evolved
through its faultless functionality into the standard in its field. With 3, 6 or 9 kg of
resistance, it is the most powerful system available. It effortlessly compensates
for the expansion and contraction of your greenhouse by ensuring a firm seal
of your screen all around. It pulls the screen open to form the smallest possible
package. And it ensures extremely uniform ventilation slits to allow moisture to
escape. The KliMax Compac

‘Next generation cultivation’ already forms part of many cultivation
strategies. It stands for optimal production with lower energy use. Its most
important elements are:
• Moisture control under the screen
• Longer use of the screen more often
• Better handling of CO2 as there is less natural ventilation
The accuracy of the ventilation is an essential component of this. The

A cabrio greenhouse combines the advantages of cultivating in a greenhouse
with the advantages of cultivating outdoors. But then it must be possible to
open the greenhouse roof fully and retain stability.
The ValkCabrio vent push rod/rail system of Van der Valk Horti Systems
meets this need effortlessly. The system is distinguished by two push/pull
tubes placed above or next to each other and a unique patented telescope
construction for maximum ventilation possibilities.

Literally and figuratively designed from a different approach, the
ValkTriplePlus screen profile scores better than its predecessor(s) in three
important aspects: light gain, flexibility and assembling speed.
The design: screen profiles are generally narrow at the top and wide at
the bottom. The ValkTriplePlus profile is exactly the other way around. Its
narrow bottom produces a smaller package of screen cloths, while the
wider top keeps the profile strong. It also limits the blousing of new screens

Van der Valk Horti Systems is introducing a new drive technique for screen
systems: the XLDriveLine. It is well-known that cable-driven screen systems
that are longer than 100 m are considerably less accurate. The traditional
3 mm steel cable just has too much stretch at that distance. That is why
three screen systems are often placed in greenhouses with a gutter length
exceeding 200 m.
This is no longer necessary with the XLDriveLine. With this new technology
