Valve positioners for precision automated flow control from Bonomi
Bonomi North America introduces a new digital smart valve positioner that provides precision automated ball valve control with the company’s Valbia pneumatic actuators. Its durable design and NEMA 4X (IP66) enclosure make it ideal for harsh industrial environments, Bonomi says. Advanced automatic self-calibration ensures optimal performance, the company adds. The Bonomi smart positioner uses a microprocessor to position the valve actuator while monitoring and recording data. It functions like an electro-pneumatic analog-type positioner, except the electronic signal conversion is digital. The SP series is very accurate, uses less air and allows for online digital diagnostics, Bonomi notes. The new unit provides continuous valve position control. HART communication and 4-20 mA input is/are optional.
