ValkScreenVision 2.0
The most advanced screen system for Venlo greenhou
The most advanced screen system for Venlo greenhou
Van der Valk Horti Systems has introduced a completely new screen insertion system: ValkScreenVision 2.0. This system makes inserting and replacing screen cloth a lot less time-consuming and less risky for both crop and fitter.
The screen cloths come pre-fitted with guide strips that are pulled directly into the profile as the cloth is inserted. This means that cloth clips will not have to be fitted and you can insert as much as 3 hectares of cloth per day!
Given that it minimises the need to move between

ValkClip
Screen System
Screen System
The ValkClip system is a low-budget horizontal screen system.
This tried-and-tested system has more than proven itself over the past years and is a precursor of the next generation of screen profiles.
Simplicity comes first with the ValkClip system. The screen cloth for this system is fixed to the screen profile using stainless steel cloth clips. The affordable screen profile and accessories deliver outstanding functionality in situations where things such as installation time and light gains are top prio

Ventilation mechanism
Ventilation mechanism
‘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 ValkTrussRail vent-opening system from Van der Valk Horti Systems prevents poorly shutting vents and produces extremely even ventilatio

ValkTwinRail
Ventilation mechanism
Ventilation mechanism
The ValkTwinRail ventilation system has a unique construction, with the pullpush tubes (for individual control of the two air vent sections) installed on top of each other on the truss. This allows the two sets of push rods (from the uppermost and lowermost pull-push tube, resp.) to move through each other, and the screen can sit freely against the truss.
The ValkTwinRail system consists of a hinge element with an exceptional form that keeps the push rods together in a steel grip. And it has a unique tu

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 ValkCabrioRail 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.

ValkGableVision
Vertical screen system
Vertical screen system
Roller gable screens, i.e. vertical screens, are used for various purposes, such as for extra energy savings, sun shading, darkening, and to limit light emission of assimilation light.
The ValkGableVision system can be integrated completely into the greenhouse structure. Combined with a horizontal system, you can create even more constant, horizontal temperature distribution in your greenhouse. In wide-roof greenhouses, this system is used as a roof roller screen, enabling you to utilise the maximum volume

Semi-advanced screen system
Semi-advanced screen system
The ValkScreenVision 1.0 semi-advanced screen system is based on the ValkTriplePlus screen system. This means that you still get the benefits in terms of light gains, smoothness, and installation speed. ValkScreenVision 1.0 adds a key benefit to that: it’s future-proof.
The ValkScreenVision screen profile in this installation offers the option to attach the screen cloth using the well-known cloth clips, but is also ready for the advanced screen insertion system using cloth strips.
This allows growers to

Outder screen system
Outder screen system
The climate inside a greenhouse is easier to control when certain weather factors can be ‘screened out’ before they enter the greenhouse. Keeping sunlight out, for example, reduces irradiation and keeps temperatures down, which is especially important when growing premium ornamental plants such as orchids and roses.
On top of that, outer screens also help keep power consumption down, because they reduce cooling needs and increase CO2concentrations thanks to less ventilation loss. And thanks to outer screen
