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.
