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 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.

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.

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.
