ValkCabrio | Ventilation Mechanism
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.

Common properties
of the ValkCabrio types 2, 3 and 4
- Stronger due to larger diameter of push/pull tubes
- Larger ventilation sections with fewer motors and less wiring
- Unique calculation program: - calculated in detail for every situation
- developed in collaboration with TNO Bouw
- calculates forces exerted on the entire system

ValkCabrio type 2
Two push/pull tubes above each other
- Set of push rods move simultaneously on the upper and lower tube
- Is combined with Valk-Plus vent push rods and StabiMax hinge element
- The screen can sit freely against the truss
- Screening on upper beam possible
- Double consoles
- Guaranteed ‘free-running' of the push rods
- Calculation programme calculates the space required between the two sets of push rods

ValkCabrio type 3
Two push/pull tubes next to each other
- Simultaneous movement of steel push rod tube left and right of the truss
- Option with aluminium Delta vent push rods
- Single consoles
- Consoles symmetrically positioned
- NB: for screening on the upper beam, the consoles have to be raised
|
|
ValkCabrio type 4
Two push/pull tubes next to each other and overlapping greenhouse covering
- Same as ValkCabrio type 3, but with more travel due to the asymmetric position of consoles
- Prevents rain entering due to overlapping greenhouse covering
- NB: for screening on the upper beam, the consoles have to be raised

Telescope construction: minimal forces
Van der Valk Horti Systems developed a clever telescope construction (patented) for the ends of the push/pull tubes.
With this fully rolling construction, greater travel distances are realised, without having to tilt the push/pull tube.
Result: minimal forces exerted on the greenhouse construction.

Sustainable
For the required stability, the ValkCabrio type 2 ventilation mechanism use the StabiMax ventilation systems and the Valk-Plus push rods. These two familiar innovations of Van der Valk Horti Systems are now being employed all over the world.
For the required stability, the ValkCabrio types 3 and 4 ventilation mechanism use steel push rods. Option to fit with aluminium Delta push rods.
