COAX MK / FK DVGW Certificated Valves

The COAX MK / FK DVGW certified valves are direct-actuated 2/2-way solenoid valves, designed for safety shut-off in fuel supply applications. Available in DN 15 to 25 with a pressure range of PN 0 to 40 bar, these valves feature pressure-balanced, spring-return mechanisms and are available in nickel-plated steel bodies with PTFE, FPM, and special seal materials. Compatible with DC 24 V or AC 230 V, they quickly close within one second if voltage drops, ensuring secure containment of combustible gases per G260.
