Hand lever valve with priority valve

de
HH5/2-VVAZ-5xB1-6/4

Description

Valve combination consisting of a hand lever valve HH5/2 and a mounted priority valve (VVZ or VVAZ) for controlling smoke and heat extraction and ventilation units. Thanks to its modular design, the valve offers numerous expansion options.

  • Manual operation by turning the hand lever:
  • Hand lever up = OPEN
  • Hand lever down = CLOSED

Using electrical add-on components (EA / EZ), the valve can also be electrically controlled OPEN / CLOSED, whereby one attachment can optionally have priority over the other.

Using pneumatic add-on components (PA / PZ), the valve can also be pneumatically controlled OPEN / CLOSED, whereby one add-on component can optionally have priority over the other.

For details on VVZ and VVAZ, see Priority Valves.

With factory-installed screw fittings upon request.
