Manual Plunger Valve(Needle Valve)

Needle valves (plunger valves) are widely used for flow control or control of flows with high pressure differences.

Thanks to the special inner construction, the flow cross section is circular which allows
for precise control.

The flow is always guided to the center of the connecting pipe where cavitation
bubbles will be formed and restored without damaging the equipment.

Normally, the needle valve closes in clock-wise direction unless otherwise mentioned in the customer’s order.
