Area of use

The thermostatic radiatorvalve Evoflow is used in heating-, cooling and tap water systems.
Evoflow can be used as a loose valve or mounted in manifolds.
Evoflow is used together with a thermostatic head, actuator or a manual hand wheel.

Description

The thermostatic radiatorvalve Evoflow has an exact pre-setting function, placed under the stuffing box
Evoflow are designed for modern installations and are ideal for systems with low energy consumption.
Evoflow is manufactured in low lead brass for the least possible environmental impact.
The thermostatic radiatorvalve has a linear characteristic in the work area forthermostats with a limited temperature range.
The characteristic provides high precision regulation.
Evoflow can handle high differential pressure before there is any risk of noise.

Capacity

The thermostatic radiatorvalve Evoflow is chosen with 5 kPa differential pressure for dimensioning the valve at the desired flow
MMA recommends a minimum of Kv 0,03 in a normal heating system.
Read the settings or the Kv value in the diagram before pre-setting the valve.
For valves that will be used with a thermosatic head use the scale KvΔT2K.
For valves that will be used with an actuator use the scale for Kv.

Preset

The presetting is done with the FN2 presetting key or the FV 22 tool by opening a number of turns from closed valve in line with the pressure drop diagram.
Unscrew the protective cap. Remove the stuffi ng box with the pin (using the top of the FN2 presetting key).
Insert the presetting key with the serrated end in the control sleeve and screw it carefully to the
bottom (clockwise).
Screw up the number of turns outlined in the diagram.
Refit the stuffing box with the pin.
