Rho marking for cylinder valve designs supplied to the GB market

Due to Brexit, all new Transportable Pressure Equipment (TPE), like gas cylinder valves placed on Great Britain (GB) market after 1st January 2023, must be stamped with a Rho mark. The Rho mark is stamped on TPE following successful conformity assessment by a GB Appointed Body to show that the TPE is in conformance with the GB Regulations.

This requirement comes from the 2020 amendment (EU exit) of the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009.   

Tekno Valves is pleased to announce certification for “Rho” marking for several cylinder valve designs supplied to the GB market from the UK-notified body Arrowhead. These valve designs shall be supplied with dual “Rho and Pi” marking to allow the valves to be transported and used within Great Britain and the EU.  For more details, refer to our website.  
We continue to service our customers within GB and EU with dual marking on cylinder valves.
