The KIT Consist Of;
• 2 ways valve body with 2 connections and 3-ways valve body with 4 connections with built-in by-pass
made of brass, maximum working pressure 16 bar.
• Electro-thermal actuator having the following specications:
• Power supply; 230 VAC, activation; NC (Normal Close) and ON/OFF,
• Total opening time: 3 minutes.
• Cable lenght: 1 meter
• Protection class: IP44 to EN 60529
• Power consumption (normal operation): 2,5 W
! Caution: During mounting hydraulic kit to unit should be used the required amount of extra sealing
material to seal between tting connection points for unmounted units.
! Caution: After mounting hydraulic kit, installer must be ensured that there is no any leakage on all
connection points.
Hydraulic kit for the installation of the valve on the heat exchanger.
The ow resistance of the valve is obtained from the following formula:
Pw = (Qw/Kv)2
Valve Kv Direct Passage Kv By-Pass
2 Ways 3/4" 2,8 -
3 Ways 3/4" 2,8 1,8
Where:
Pw is the ow resistance expressed in kg/cm2.
Qw is the water ow rate expressed in m3/h.
Kv is the ow rate identied in the table.
