DESCRIPTION
The smart balancing and control valve EBV system is composed by the following elements:
• smart high resolution actuator able to collect and elaborate all the data coming from sensors and the BMS (via Modbus) in order to properly position the control valve;
• flanged Globe Valve with equipercentage control characteristic equipped with pressure sensor plugs;
• a couple of high resolution pressure sensors able to continuously monitor the valve differential pressure;
• a couple of NTC 10 kOhm temperature sensors with stainless steel cases able to continuously monitor the supply and return fluid temperature.
EBV can be controlled by 2 types of signal:
Modbus command;
modulating (or proportional) with selectable range of action 0-10Vdc (default), 2-10Vdc, 0-5/2-6Vdc, 5-10/6-10Vdc and 4-20mA.
The command mode can be set via Modbus or via USB or via the dipswitches on the board.
