Greenfloor stainless steel manifolds
All Greenfloor manifolds are manufactured from stainless
steel and include flow meters for accurate system
commissioning. A full range of accessories is available
including ball valves and connectors.
The pre-assembled stainless steel manifolds serve 2-16
zone applications. They are supplied with integrated valves
providing a filling and draining facility and automatic air
vents. In the event of additional zones being required,
manifolds can be joined together. The flow rate can be
accurately set on flow meters for safe and rapid setting
of the values provided by the Worcester Design Service.
The return manifold provides threaded connections for
installation of electronic actuators.

Manifold cabinets
Greenfloor manifold cabinets are constructed from 1mm
galvanised sheet steel. The recessed type allow a flush
finish to a plastered wall and feature pre-punched side
openings for manifold connections and pipe penetrations
at the top and bottom. They are also height adjustable
to align with the screed thickness. A surface mounted
version is also available. Both the recessed and surface
mounted cabinets are lockable to prevent unauthorised access.
