Description
The Multifunctional Control MBC-VV combines two automatic shutoff valves in one compact housing. Both valves
can be wired independently or in parallel.
Internal profiles and compact design optimize flow and provide a low pressure drop. Two body styles reduce
inventory.
Directly mounting the following accessories creates a compact valve train without additional piping:
-High and low gas pressure switches
-Valve proving system
-Test ports (Manometer)
Application
The MBC-VV is recommended for industrial and commercial applications using spark ignited, gas engines for standby and prime power generation.
The MBC-VV is suitable for natural gas,propane gas and other manufactured gases (e.g. syn gas). Suitable for up to
0.1 % by volume, dry H 2 S.
Two normally closed automatic shutoff valves in one housing.
