Welcome to the JLS Valves website
James Lister & Sons have manufactured the renowned Ermeto/Alenco range of valves for over 30 years.
They are available in various materials with pressure ratings up to 700 Bar (10,000 PSI).
All valves are hydraulically proof tested using our in-house hydraulic, water and skydrol test facilities to one and half times the maximum recommended working pressure.
Valves can be manufactured to incorporate special features as required by the customer or re-designed to suit your special requirements.
