Shut-off valves, pressure control valves and
flow control valves VBNF/VFOF-LE-BAH

VBNF VFOF show enlargement

Function combinations provide high performance with minimal space requirements

  • Fewer components thanks to function integration: faster assembly and commissioning
  • Save costs: from ordering to logistics
  • Up to 50% space saving
  • Energy efficiency thanks to fewer interfaces
