Icma 889 | Chromed steel probe

Angled valve for thermostatic control devices.
Equipped with an anti-dripping nozzle and for connection to the 1/2 “iron pipe.
The connection for thermostatic controls devices is
M28x1.5mm.

Valve Installation

The ICMA thermostatic valves must be installed in the system respecting the flow direction, which must enter from
the connection part to the system and exit towards the heating body.
Attention in case of incorrect installation the following problems may arise:
– The appearance of a noise similar to a strong and continuous hammer is due to the fluid that is passed through
the valve in the wrong direction, the only solution to this problem is to reverse the valve with the holder on the
radiators that manifest the problem, restoring the correct direction of the fluid in the valve.
– The appearance of a sound similar to a loud hiss during modulation is due to an excessive prevalence present in
the valve. To solve this problem it will be sufficient to keep the system pressure under control by providing variable
speed pumps combined with differential pressure regulators, or the use of differential by-pass valves.
