Needle – Plunger Valves

Technimex needle valves, also called plunger valves are used for flow control with high different pressures. Long service life is guaranteed as the bearings do not come into contact with the medium.
Precise control is possible by the circular flow cross section. The flow is always guided to the center of the connecting pipe where cavitation bubbles will be formed and restored without damaging the equipment.
Upstream and downstream pressure in combination with required flow rate define the type of ring to be used in order to have excellent cavitation behavior and minimum pressure loss.
The needle valve is suitable for use in water treatment, water distribution, in dams, power plants and in several other industries. Needle valves can be operated with hand wheel and gearbox or with electric actuator.
