In addition to manufacturing our own brand of products Langley, YPS Valves Ltd has established a reputation for stocking one of the most comprehensive ranges of high quality valves in Europe. We stock products from Calobri, Velan, OMB and Neway; all of which are high quality approved manufacturers used by many leading end users.

As a manufacturer and stockist, we are able to convert a stock valve to meet the requirements of almost any end user in the world. Whether a client requires a sophisticated cryogenic or bellows sealed conversion, an ex-stock valve up-grading to meet stringent gas leaking test requirements, or more simply a trim change, we can facilitate all of these modifications in-house within short timescales.
