Needle valve is the right valve to use whenever pressure heads or flow rates need to be safely and reliably reduced and controlled. They are used for two main tasks:
• By restricting the cross-section, a change in flow rate, flow velocity and pressure is forced, which results in higher stress in the valve. The valve must therefore be designed so that potential cavitation cannot cause any damage whatsoever.
• To be able to control the pressure and flow precisely and finely, the control valve’s control characteristics must be as linear as possible over the whole operating range.
Thanks to their well thought out and tested design, Needle valves fulfil these requirements to the greatest possible degree and are therefore the ideal valves for numerous control tasks.
