Bonomi ball valves for flow control precision

11 September, 2018

Bonomi (UK) Ltd has introduced a V-Notch option called ‘Vball’ to the best-selling ball valves in its range, enabling users to achieve even greater stability and accuracy in terms of flow control.

A wide variety of valves are available with a Vball including Inox-val, Radiamont, Wafer, Split-body and Wafer-split. Virtually any customer requirement can be catered for using V30-60, V60 and V90 patterns with additional special patterns available on request.

Available from 1/2” in all new sizes, the Vball can be used with liquids and gases, enabling an accurate and precise flow control with a range up to 500:1.

Validation methodology

Each valve’s design has been validated using FEA Software (finite element analysis) CFD Software (computational fluid dynamics) and Flow Loop testing. CV and KV curves are also available.

Using specialist Valpsize configuration software, valves can be sized (ISA 75.02, IEC 60534-2-1) checking fluid velocity, valve openings, noise and other critical issues. Valpres control valves are available with a manual calibrated lever with opening and flow direction indication and can be configured with Valbia pneumatic or electric actuators to fit individual users’ flow control needs.

The Vball range has undergone rigorous testing at Bonomi’s Rubinetterie Bresciane laboratory and other third-party test facilities. Endurance testing has been conducted beyond CV/KW, noise and valve parameter measurement (FL, Xt..). Valves are offered with graphite filled PTFE seats.
