Guide Valve Supply Ltd (GVS LTD) is highly dedicated to the quality of our products; all the valves we produce are subjected to rigorous quality control testing standards according to in-house procedures.

We perform chemical analysis and testing of the mechanical properties of materials for pressure-containing parts and main components, all according to the applicable material specifications. As well, inspections are made on the identification of all materials and on compliance with appropriate documentation. The components themselves are subject to a visual and physical examination, which encompasses a coated surface inspection and a dimensional examination of assembled valves according to the applicable outline drawings. Finally, those valves equipped with their own operators have operational tests performed on location in order to ensure functionality.

GVS LTD. valves are mainly designed, manufactured and tested according to API Spec 6D, normally for ANSI Class 150 through 2500 but can be built for different pressure–temperature ratings or in compliance with other standards on request.
