What makes the ValkPoly+ unique?
-
The ValkScreenProfile is the basis of the system. The distinctive, unique shape makes the profile stronger than the conventional screen profile and enables perfect coupling without extra interventions or attachments. You can just slide one into the other. This means less costs for you!
Unique shape Easy to slide one into the other Perfect coupling Saves you time and money
-
The ValkWireGuide makes sure that the profile and polyester wires can move independently from each other, so that no load is placed on the structure in case of expansion and shrinkage.
Compact design. Easy to attach in the upper and lower part of the ValkScreenProfile. Prevents wear of the ValkScreenProfile. Prevents light loss thanks to black stripes on the screen cloth.
-
Free software for detailed project calculations.
Here’s how it works:- Go to www.valkhortiplanner.com, log in or create an account and start calculating.
- Use ‘Adjust floor plan’ to specify the floor plan.

ValkScreenDrive: The right screen drive system for any poly greenhouse
With three different drive types to choose from, you will always get the right system for your greenhouse!
-
Push/pull (type 1)
-
Pull wire (type 2)
-
Semi-push/pull (type 3)
Push/pull drive system
Suitable for any type of poly greenhouse
Racks required (to be purchased externally)
No load on greenhouse gables
How does it work?
Works using a push/pull tube and rack.
The push/pull tube moves to either side on a rack to open and close the screen cloth.
Unique ValkScreenDrive Type 1 components (Push/pull)
The ValkScreenDrive is made up of only a couple of multifunctional components that work in perfect harmony with each other. The ValkPolyStrip is the centre of the drive systems. Thanks to its smart design, it acts as a connector between as many as four components. This means you need fewer installation items, which considerably simplifies stock management needs.
-
With ValkScreenDrive Type 1 and 3, the ValkPolyStrip fixes not only several unique system components together, but also the ValkRollerBracket drive component.
Multifunctional. Simplifies stock management. Grips the closing wire at the same time.
-
The ValkDriveTube pulls and pushes the screen to open and close it.
Galvanised Contiflo tube, prevents white rust. Suitable for heavy duty (such as with darkening or shading cloth with opened ventilation windows) Available in two diameters: 27mm and 32 mm. Available in standard lengths. Easy to fix to any make rack. Reduced coupling with flange nut/flange bolt link.
-
The ValkTableClamp is the ideal connection between the ValkDriveTube and the ValkScreenProfile.
Available in versions for a 27mm and 32mm tube. Extra strong bond thanks to hollow profile. Easy and solid installation with only one bolt.
-
The ValkRollerBracket guides the ValkDriveTube.
Simple installation. Use of patented plastic rollers. Freedom of movement of the rollers effortlessly absorbs expansion differences between steel suspension tube and aluminium screen profile.
-
The ValkRollerClamp fixes the ValkDriveTube to the ValkScreenProfile in case of deviating section sizes.
The ValkRollerClamp then replaces the ValkTableClamp to guarantee a perfectly closing screen cloth in this irregular section as well.Compatible with a 27mm and a 32mm tube.
Pull wire drive system
More affordable
Powers larger screen sections with a less powerful motor
Greenhouse must be able to withstand this system’s forces
How does it work?
Works using a steel pull wire and ValkPolyCord. This ‘cord’ can be wound around a thinner drive shaft that can be powered using a less powerful motor.
Unique ValkScreenDrive Type 2 components (Pull wire)
The ValkScreenDrive is made up of only a couple of multifunctional components that work in perfect harmony with each other.
-
The ValkPoly+ version of the ValkDriveShaft is located in the centre of the screen section. The shaft winds and unwinds the ValkPolyCord to open and close the screen.
Reduced shaft: easier to couple thanks to dual bolt/nut connection. With a 5/4” tube diameter, the system can be powered by a less powerful motor.
-
The ValkWireSleeve ensures the ValkPolyCord winds and unwinds neatly.
Suitable for installation on the 5/4” drive shaft. Grooves on the ValkWireSleeve guide the ValkPolyCord. Holes on the ValkWireSleeve indicate when the right number of windings has been reached.
-
The ValkPolyCord replaces the steel pull wire at the level of the drive shaft.
Can be wound more tightly than a steel pull wire, so that the drive shaft can be thinner. A thinner drive shaft means you can use a less powerful motor. Cost savings because you need fewer motors.
-
The ValkPolyClamp makes a screen system controllable and effective, both when it comes to opening and closing the screen cloth and when it comes to regulating moisture gaps.
Delivers light gains thanks to compact structure. Unique design provides a strong bond to the ValkScreenProfile.
-
The ValkKliMax raises screen system controllability and effectiveness to the maximum level, both when it comes to opening and closing the screen cloth and when it comes to regulating moisture gaps.
The ValkKliMax ensures perfect closure in all situations, extremely uniform moisture gaps, and the smallest possible cloth package.
First aligns screen profiles for uniform moisture gaps or even heat discharge. Guarantees controlled forces on the greenhouse structure. Delivers light gains thanks to compact structure.
-
The ValkReversingWheel makes sure the stainless steel pull wire is guided along the gable and returned at a section division.
Readily available, in single or double version. Pre-installed in aluminium casing with plastic wheels. Double bearings to be able to handle greater forces. Easy to mount on standard-size profiles.
-
The ValkBearingBracket guides the ValkDriveShaft and can be mounted to the greenhouse structure in a variety of ways.
Prevents cutting of the drive shaft. Optimized placement of the bearing guarantees resistance to the forces of the ValkDriveShaft.
-
The ValkPulley supports the return wire of the pull wire drive (type 2), so that it cannot sag and the system will continue to run smoothly.
Multiple mounting options so it always fits. Can be opened, meaning that it can also be fixed to the return wire later. Can be opened, making it easy to remove or replace.
Semi-push/pull drive system
Cost-effective and compatible with any type of greenhouse
Powers larger screen sections with a less powerful motor
Without a rack
No load on greenhouse gables
How does it work?
Works using the push/pull tube and ValkPolyCord.
Combines the benefits of a push/pull system with those of a pull wire system.
Unique ValkScreenDrive Type 3 components (Semi-push/pull)
The ValkScreenDrive is made up of only a couple of multifunctional components that work in perfect harmony with each other.
-
With ValkScreenDrive Type 1 and 3, the ValkPolyStrip fixes not only several unique system components together, but also the ValkRollerBracket drive component.
