    PressureTech Ltd.

    Pressure Tech is a UK manufacturer and was established in 2000 by owner Steve Yorke-Robinson. We are now renowned world over for the manufacture of high-quality pressure regulators. In 2017 we started work on expanding our product range into the Hydrogen Fuel Cell market with the development of our lightweight LW351 pressure regulator for UAV H2FC drones. We have since added an EC79 approved regulator for Hydrogen buses and trucks, a TPED approved cylinder valve for Hydrogen gas cylinders and a full range of pressure regulators for material handling applications, passenger vehicles and refuelling stations.
