ValkCabrio | Ventilation Mechanism

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.
