Motorised butterfly valve DMK Dungs

Motorised valve DMK
  • These motor valves DMK are used for regulating the gas supply on gas burners and gas equipment.
  • DMK is an actuator without zero shut-off as per DIN 3394, Sheet 2.
  • Designed to be used together with actuator DMA...P, DMA...Q, DMA...A but other drives can be supplied on request. Prepared for mechanical and electromechanical actuator drives.
  • Maximum operating pressure: 500 mbar, maximum differential pressure of 100 mbar for threaded models and 250 mbar for flanged.
  • Reduced installation length by a combination of female and male threads. Bigger models achieve this by using an intermediate-flanged design.
  • Application-specfic throat diameter selection of throttle valves.
  • Functional, rugged and maintenance-free.
  • In combination with SAD 1.2 they are used for automatic burner controls MPA22.
  • Does not contain any non-ferrous metals, suitable for gases of up to max 0.1% vol H2S, dry. Can be used for gases of families 1, 2, 3 and other neutral gaseous media.

Equipment selection

  • The following values must be known for the DMK rating:
1) Maximum volumetric flow: Vmax
2) Pressure loss Δp at maximum volumetric flow.
3) Minimum volumetric flow: Vmin
4) Pressure loss Δp at minimum volumetric flow.
  • The throat diameter can be determined optionally using the kv value or the diagrams 1, 2 and 3. Check whether the required minimum volumetric flow is attained in valve position 0o. If the calculated or read-off value is below the specified minimum volumetric flow, the valve can be used.
  • At smaller volumetric flows, the pressure loss of upstream equipment is reduced and the available Δp of the valve increases. Always select the valve with the largest pressure loss (Δp > 10 mbar) to achieve a good regulating behaviour.
  • For use in the area of subcritical flow condition, the following applies:
Nominal flow DMK

 

Legend:
Vn (m3/h) volumetric flow, normal state ρn (kg/m3) standard density of gas
Δp (bar) pressure loss via DMK T1 (K) gas temperature upstream of DMK absolute
p2 (bar) pressure downstream of DMK absolute
