Balancing Ball Valves / Regulating Ball Valves / Control Valves
The Vexve balancing ball valve (type Naval) is a line regulating valve with a combined shut-off and control function
and thus combines the high shut-off capabilities of a ball valve with optimum flow control.
The special features of the Vexve balancing ball valve are its precise measuring accuracy and low flow turbulence.
Thanks to the newly developed control ball with V-port, the flow is controlled even more effectively than with conventional control valves
with a consistently low resistance value and absolute tightness when closed.
Cavitation and noise are almost completely avoided.
Vexve balancing ball valves are used for shutting off and regulating mainly in heating and cooling systems.
