Needle Valves
Needle valves are the suitable 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 to 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 opening range.
Petro Valves has been at the forefront of Needle Valve technology. Our range of Needle Valves offer true reliability and safety under high pressure.
Our Needle Valves are the most unique valves on the market today, offering a diverse range of features and added extras to ensure that our customers are able to benefit from maximum efficiency through the Oil and Gas extraction process.
