Needle valves, sometimes referred to as plunger valves, are regulating valves and enable engineers to finely control and regulate water flow and pressure. The precision is achieved through the fine movement of the shaft, which enables the gearbox to move the piston tube in sliding motion towards the opening or closing position, depending on the requirements from the control system.

• Symmetric flow path with annular flow cross-section in any open position

• Internal body shape is optimised to give a low head loss coefficient in fully open position

• All ductile iron parts coated with min. 250 µm fusion bonded epoxy

• Shaft sealing with double O-rings

• Main seal in the no-flow zone at the valve outlet

• 4-6 guide rails ensure very low vibration

• Gaskets in thermoplastic PUR for high resistance to abrasion

We can cut from one off blanks to the largest production run for immediate or just in time deliveries.
