The COAX VSV-M / VSV-F DR 3/2-way externally controlled coaxial valves are designed for precise fluid control across a range of pressures (PN 0-40 bar) and orifice sizes (DN 40-150). Constructed with pressure-balanced designs, spring returns, and switching overlaps, these valves suit applications involving gaseous, liquid, highly viscous, or contaminated media. Available in aluminium, galvanised, nickel-plated, and stainless steel bodies with NBR, PTFE, FPM, CR, EPDM, or specialised seals, they operate on DC 24V or AC 230V with threaded or flanged ports.
