COAX MK / FK DR Ex Certificated Valves

The COAX MK / FK DR Ex Certificated Valves are direct actuated 3/2-way safety shut-off valves designed to handle gaseous, liquid, highly viscous, and contaminated media. Available in DN 10 to 50 sizes, they operate within a 0-40 bar pressure range and come in brass, nickel-plated, galvanised, and stainless steel bodies with seals like NBR, PTFE, FPM, CR, and EPDM. With threaded or flanged ports and a spring-return, pressure-balanced design, they operate on DC 24V or AC 230V, sealing within one second if voltage drops for reliable shut-off.
