Needle Valves
Commonly used as concentrate control valves (also referred to as system pressure control valves) in RO, UF, NF, MF, SWRO Membrane Water Treatment Systems, needle valves use a tapered pin to gradually open or close the water stream, allowing for precise regulation of flow.
Needle valves are ideal for continuous use applications where a liquid stream must be maintained at a constant adjustable flow rate.
Available in Brass and Stainless Steel models.
