Needle Valves
For liquids, gases and steam in hydraulic, pneumatic, heating and steam systems, chemical and food industries application.
These valves are fully constructed from laminated bars. They can, upon request, be manufactured in other types of materials, for use in special working conditions (high temperatures, fluids, etc.). These valves have PTFE (Teflon) packing and Stainless Steel hand wheels or handles (DIN-1.4401) (AISI-316).
