Proportional technology
The applications of this technology are virtually unlimited
What is and how it works
Our proportional valves offer the possibility to control and regulate a fluid based on an electronic signal
This technology has become the optimal solution during the last few years for the growing need to electronically control, with extremely high precision and remotely, an increasing number of parameters such as pressure, capacity, level, dosing, etc, of gases and liquids, optimizing therefore the productivity of a system.
Our proportional valves offer the possibility to control and regulate a fluid based on an electronic signal. The difference between the set regulation value and the instantaneous valve is controlled through an internal PID and sensor: the algorithm of PID type ensures the control and regulation at closed ring of the variable measured.
This system guarantees that the pressure or capacity value set by the control circuit is actually present downstream the proportional valve used.
Our proportional valves have the following characteristics:
- Body material: brass AISI 316, Aluminium, plastic material
- Gasket material: NBR - Viton - EPDM - PTFE - HNBR - CR - RULLON – metal or other based on the fluid to stop
- Connections: from DN3 to DN100
- Pressures: from vacuum to 1000 bar
- Supply voltage: 24VDC
- Command signal: analogue, digital, field bus
- Feedback analogue, digital
- Protocols: ASI, Profibus, EtherCat, EtherNet
High performances
- Extremely fast speed and response times
- Maximum discharge
- Excellent precision and repeatability
- Balanced shutter
