More Information

Overview Manuals Valve Stages Pressure & Ports Name Mapping Coil Verification

Features:

  • Two normally closed safety valves act in series on the same gas passage.
  • The VV function code identifies a valve assembly without an integrated pressure regulator.
  • The W-MF 512 C01 certificate limits inlet pressure to 360 mbar.
DUNGS W-MF 512 C01 corresponds to the current MBC-700-VV designation and the earlier MBC-VV 2500 name.

The paired stages in W-MF 512 C01 provide two separate closing elements within one certified valve assembly rather than two unrelated pipe components.

Connection marking remains part of model selection because W-MF 512 C01 covers Rp1 through Rp2 bodies and DN25 through DN50 nominal sizes.

The DUNGS W-MF 512 C01 MBC-700-VV Dual Safety Shutoff Valve may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the two shutoff elements share one path

  • Series layout: Gas passes through two automatic shutoff stages in sequence.
  • Normal state: Both stages remain closed without their commanded actuator supply.
  • Opening action: The certified VV arrangement uses fast-opening operation.
  • Closing action: Each stage returns with fast-closing behavior.

Match the certificate rating to the valve body

  • Pressure limit: The W-MF 512 C01 designation is certified for 360 mbar or 36 kPa inlet pressure.
  • Threaded bodies: Certified connection marks extend from Rp1 through Rp2.
  • Nominal sizes: Those bodies correspond to DN25, DN32, DN40, and DN50.
  • Selection point: The installed pipe connection must agree with the marked valve body.

Read the three documented designations together

  • Ordering name: W-MF 512 C01 is the certificate's alternate model designation.
  • Current type: MBC-700-VV is the corresponding current DUNGS designation.
  • Earlier type: MBC-VV 2500 is the previous designation recorded in the same certificate.
  • Function suffix: VV identifies the dual-valve arrangement without an integrated regulator.

Use the actuator label for electrical selection

  • Actuator families: The certificate covers 042/P and 042/2P actuator arrangements.
  • AC variants: Certified coil options include 110 V, 120 V, and 230 V at 50–60 Hz.
  • Variant boundary: Those options do not make every coil voltage identical on every valve.
  • Field check: The installed actuator marking determines the required coil supply.
Description
DUNGS W-MF 512 C01 identifies the MBC-700-VV dual safety shutoff valve assembly in the MBC multifunctional gas-control family, where two automatic valves control one burner-gas passage.

Both shutoff stages inside W-MF 512 C01 are normally closed and arranged in series. Each stage closes the same flow path, while the VV function code distinguishes this valve-only arrangement from MBC configurations that combine valves with a pressure regulator.

Pipe selection for W-MF 512 C01 must follow the marked body connection because the certified designation covers Rp1, Rp1¼, Rp1½, and Rp2 bodies, corresponding to DN25 through DN50. The W-MF designation carries the documented 500 mbar / 50 kPa maximum inlet-pressure rating.

The designation chain for W-MF 512 C01 connects the current MBC-700-VV name with the earlier MBC-VV 2500 name. This mapping identifies the same certified valve arrangement without treating every MBC-700 variant as the VV configuration.

Technical notes
DUNGS W-MF 512 C01 maps to MBC-700-VV and MBC-VV 2500, with two normally closed shutoff stages and a 500 mbar / 50 kPa maximum inlet-pressure rating.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which maximum inlet-pressure rating applies to DUNGS W-MF 512 C01?
DUNGS W-MF 512 C01 carries the W-MF rating of 500 mbar or 50 kPa. The 360 mbar value belongs to the technically identical MBC designation and must not replace the W-MF nameplate rating.
Does DUNGS W-MF 512 C01 contain an integrated pressure regulator?
No. DUNGS W-MF 512 C01 uses the VV arrangement: two normally closed automatic shutoff stages share the gas path, while pressure regulation must be handled by a separately documented component.
How do the two stages inside DUNGS W-MF 512 C01 control the gas path?
Gas reaches the first normally closed stage of DUNGS W-MF 512 C01 and can continue only when both fast-opening actuators energize. Removing coil power closes both stages quickly, interrupting the same passage at two points.
Which connection detail must be checked before selecting DUNGS W-MF 512 C01?
Match DUNGS W-MF 512 C01 to the valve-body mark: Rp1, Rp1¼, Rp1½, or Rp2, corresponding to DN25 through DN50.
What do MBC-700-VV and MBC-VV 2500 mean in relation to DUNGS W-MF 512 C01?
DUNGS W-MF 512 C01 is the alternate designation for MBC-700-VV, while MBC-VV 2500 is its documented previous designation.
