COAX VMK/VFK 3/2-way externally controlled coaxial valves offer precise control with an orifice size range from DN10 to DN50 and a pressure range up to PN100 bar. These valves feature a pressure-balanced design with spring return and switching overlap, and they support both threaded and flanged connections. Constructed from brass, galvanised or stainless steel, and nickel-plated brass and steel, they use seals in NBR, PTFE, FPM, CR, EPDM, or other special materials, handling gaseous, liquid, viscous, or contaminated media effectively at DC 24V or AC 230V.
