Product Overview

Construction details
Return manifold
The return manifold is equipped with manual shut-off valves (1), in
order to cut off the flow rate to each individual circuit.
They can also be fitted with a thermo-electric actuator (2) that,
when used with a room thermostat, maintains the ambient
temperature at the set values in spite of thermal load variations.
The obturator stem (3) consists of a single piece of ground stainless
steel, in order to minimise friction and prevent building up of
dangerous limescale deposits.
The headwork (4) has a double EPDM O-Ring seal (5)-(6) on the
sliding stem.
The EPDM obturator (7) is shaped so as to optimise the hydraulic
characteristics of the valve, preventing any sticking in the seal seat
after the circuit has been shut off. It minimises the noise caused by
the flow of the medium, also during the progressive opening or
closing action when working with thermo-electric actuator.
Flow manifold
The flow manifold is equipped with built-in flow meters and flow rate
balancing valves.
Using the balancing valve with the special tapered obturator, the
flow rate to the individual circuits can be adjusted accurately as
required, with the setting being read directly from the single flow
meter with a scale of 1–5 l/min (2). This simplifies and speeds up
the circuit setting process, with no need for reference graphs. After
adjustment, the valve can be locked in its open position by means
of its tamper-proof cover (3) which can be used as knob to adjust
the flow rate, when turned upside down.
The valve itself makes it possible to seal off each individual circuit,
if necessary.
