Application ________________________________________________________________________
A mcr ZIPP type valve may be used as a fire protection shut-off valve with a duct connection as well as a transfer
valve (installation without ventilation ducts).
The valve may not work in systems exposed to dust, except for when they are included in a special, individually
developed programme of service and technical inspections.
Fire resistance ____________________________________________________________________
The mcr ZIPP type fire protection shut-off valve has the following fire resistance:
EI120S for duct installation in walls and ceilings
EI120 for installation without ducts in ceilings
Performance versions ____________________________________________________________
The mcr ZIPP valve can be used as:
a valve with a thermal release – variant:
o
RST – (automatic release)
valve with an electromagnetic release – variant:
o
EK I - (remote release by operation of a "current pulse" – applying supply voltage)
o
EK P - (remote release by operation of a "current gap" – removing supply voltage)
The thermal release always has a principal role and ensures that the safe position of a valve is reached (activated)
regardless of the operation of the electromagnetic release.
Optionally, there is a possibility to provide the valve with WK1 limit switches that signal the valve operation status
(open/closed).
NOTE
As a default, the valve release temperature equals 72°C. In case another temperature value, it has to be
specified in the order,
after prior confirmation of the temperature value with the Sales Department.
