Your Valve Requirements, Our Combined Expertise

With nearly five decades of valve industry experience, manufacturing remains at the core of YPS Langley Valves. Through our Langley Valves division, we design and manufacture bespoke non-commodity valves for applications where standard products cannot meet the required specification.

Our manufacturing range includes gate, globe, check and ball valves in stainless steel, specialist alloys including zirconium, and nickel aluminium bronze. Combining established manufacturing expertise with in-house design capabilities, YPS delivers engineered solutions built around each project’s technical requirements, delivery schedule and budget.

YPS recognises flexibility is essential to meeting different project demands. We offer manufacture from bar or castings, with materials sourced from the UK, Europe or the Far East to suit project specifications and budgets. This allows YPS to select the most appropriate manufacturing route for the required valve size and quantity while balancing lead time and cost. For urgent requirements, bar stock manufacture, supported by our in-house design team, can provide a practical route to a fast-track solution.

From initial enquiry through to final inspection and delivery, our sales engineers, designers, production engineers and quality control team work closely together. This collaboration ensures that technical requirements remain central to every stage, from developing the design to manufacturing and testing the finished valve.

Our manufacturing division is supported by comprehensive modification and on-site testing facilities. Modification capabilities include cryogenic and bellows seal conversions, alongside packing, gasket and trim changes, enabling valves to be adapted for specific operating conditions.

Testing capabilities include high-pressure testing under extreme operating conditions, with temperatures ranging from −196°C to 700°C, alongside emissions testing, hydrostatic testing, dye penetrant inspection and in-house PMI verification. A dedicated clean room and ultrasonic degreasing tank support valve preparation for oxygen service.

To meet day-to-day demand, YPS also maintains extensive stock of Langley, Bonney Forge, OMB, Velan and Neway valves. This provides additional flexibility for projects requiring a combination of bespoke manufacturing and readily available products.

Continued investment in manufacturing, modification, stockholding and testing enables YPS to supply complete valve packages alongside individual bespoke solutions. With engineering expertise at the heart of our approach, YPS helps customers move from complex requirements to reliable, application-specific valves.
