What is a Labyrinth Piston Valve?

So “Doubling the service life” was the goal that the Norgren engineers set themselves in order to improve the finer points of this seasoned piston valve. The result was a modified valve in which the PTFE seals used previously were replaced by labyrinth seals and instead of the previous stainless steel piston, a compact piston now features.

What are the benefits of Labyrinth Piston Valves?

• Compact design

• Durable and robust due to high-quality graphitised PTFE seals

• High flow rate

• Solenoid interchangeable without tools (Click-on®)

Additional product features:

• Brass and stainless steel

• Maximum pressure ratings up to 40 bar (580 psi)

• 1/4 ... 2 (ISO G/NPT) port size options

Where are they used?

Valves equipped with labyrinth technology are utilised in numerous applications, for instance in the energy sector, where they are used as shut-off valves for liquid fuels. In industrial automation, they are installed in injection moulding and tunnel drilling machines, while in the food and beverage industry they are used for blowing PET bottles.
