The COAX VSV-M / VSV-F 2/2-way externally controlled coaxial valves provide efficient flow control for gaseous, liquid, highly viscous, and contaminated media across a pressure range of PN 0 to 40 bar. Featuring a pressure-balanced, spring-return design, these valves are available in orifice sizes DN 40 to 250 with threaded or flanged ports. Built from materials such as aluminium, galvanised and stainless steel, and nickel-plated steel, they operate at DC 24 V or AC 230 V, with seals in NBR, PTFE, FPM, CR, and EPDM.
