Having over 35 years of designing and manufacturing a Langley Valve, our Langley product range continues to become a preferred choice of our Customers and End Users. Over recent years our range of product has increased offering a product range suitable for general purpose applications as well as continuing to provide and develop a ‘tailored’ valve to work within critical service applications.

All of the materials selected for our Langley Product are sourced through approved suppliers who must complete YPS Valves Ltd Quality Service Test which is based on the British Standard ISO9001. Upon receipt all materials are inspected for compliance.

All of our critical service valves are manufactured on castings sourced from either the UK, Europe and the USA and are fully complaint and certified to International standards.

For general service and none critical applications we can offer a Langley Valve with either Korean or Chinese origin. All these valves are manufactured under the same control we adopt within our UK facilities and are certified by YPS Valves Ltd but can offer a more economical valve supply solution.

Our manufacturing range includes gate valves to API 600/ISO 10434, globe valves to BS1873 'T', 'L' and 'Y' patterns and swing check valves to BS 1868 or API 6D regular. All the products designed are in compliance with ASME B16.34 and the PED. We are regularly asked to produce high integrity valves for corrosive or hazardous duty to the standard of ASTM E446 levels 3, 2 and 1, depending on the criticality of the application.

Our standard production sizes for our gate, globe and check valves range from 15mm up to 400mm although we also offer a ‘bespoke’ service where we can produce customised exotic valves designed to meet clients' specific requirements. The synergy between our stocking and manufacturing businesses means shorter lead times for our clients and we are able to efficiently dispatch our products worldwide.

We are proud of our Langley Product maintains the acceptance of Shell, BP, Exxon, Mobil, Ineos, Chevron, Sasol and Conoco-Philips and Sinopec to name a few.
