Design and Development

Our design and development team are continually re-evaluating, improving and adding to our product range using the very latest CAE techniques. Abacus Valves operates with a fully integrated 3D CAD, Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) software package. In addition, we are able to utilise the same skills and experience to undertake design and manufacturing projects, allowing us to cater for any special need.


Abacus and their partners have invested both in CNC and conventional machine tools. It is part of an on-going programme designed to enable us to respond quickly and efficiently to the highest standards of craftsmanship.


Commitment to continuous improvement through employee participation, is an underpinning principle of our business approach. Quality assurance is the vehicle we use to carry through this improvement. All valves are manufactured to the applicable national standards while Abacus itself operates a quality system independently accredited to ISO 9001.
