Full plastic solution brings safety
Diaphragm valves 5-series
The full plastic design of GF diaphragm valves is a revolution and has a lot of advantages against the metal versions. The benefits of the design simplify your daily business and optimize your plant to make the best of your applications.
Optimized valve body, higher flow rate, straightforward installation and a central housing, the strength of this full plastic diaphragm valve is located in every detail. Have a closer look and find out many other features.
- No corrosion & maintenance
-
Instead of four metal screws the full plastic diaphragm valve has only one central housing nut. The result is a homogeneous expansion during temperature changes. This results in zero maintenance and no leakages during temperature cycles.
- 100% more flow
-
The development aimed to increase the flow and provide a valve for a stable process. Through the optimization of the patented valve body you benefit from:
- Double flow rate
- Linear flow characteristics
- Minimized dead space for maximal hygiene
- Absolute reliability
-
All diaphragm valves are 100% leak-tested. Even by exceeding ISO 9393-2, after passing this test the QR code and quality check sticker is put on the valve.
Packs a punch for dosing applications
Diaphragm valve type 604/605
