COAX KB / MK / FK Ex Certificated Valves

The COAX KB / MK / FK Ex Certificated Valves are direct-actuated, 2/2-way solenoid valves with a pressure-balanced design and spring return. Available in DN 2 to 50 sizes, they handle pressures from PN 0 to 100 bar and come with threaded or flanged ports. Constructed from brass, nickel-plated, galvanised, and stainless steel, they support gaseous, liquid, and highly viscous media. These safety shut-off valves, certified for rapid closure within one second, ensure reliable sealing upon voltage drop in either DC 24 V or AC 230 V configurations.
