STEAM OUTLET ELECTRIC VALVES
The butterfly valve is a safety valve with a disc-shaped shutter turning around a standard axis
of the pipe thus stopping the flow. It can be used as control valve or simply as shut-off valve.
It has proven its worth in recent years as an alternative, with allocation range up to 16 bar, to
ball valves or gate valves.
The main advantages offered by the butterfly valve are:
–
compact dimensions with consequent less space required
–
possibility to be assembled in any position
–
reduced weight with easy transport and maintenance
–
negligible load losses
–
long duration over time
Butterfly valve is adjusted through the electric actuator remotely controlled by the boiler
control panel.
STEAM NON-RETURN VALVES
The check valve, or non-return valve, is a valve allowing a single flow direction.
The disc check valves are used for the "sandwich" assembling between flanges; they are
suitable for use with a wide range of fluids for applications on process lines, cold, hot and
superheated water systems, thermal oils, compressed air, etc.
STEAM FLOW METER
Flowmeter for saturated steam, in sandwich design, i.e. in-between two flanges, equipped
with built-in electronics providing an output with density compensation.
The electronic head is equipped with an LCD. Instant flow rate signal is transmitted through
a 4÷20 mA output.
ELECTRICAL ENERGY METER
–
Electrical energy electronic meter.
–
Connection and insertion with TA.
–
Number of poles: 3 poles + neutral.
–
Measure of power, active and reactive energy.
–
Communication port protocol: ModBus, RS485.
–
Insulation class: IP20, IP40.
