Bonomi North America, Charlotte, N.C. USA, reports that its new Valbia® Series 86 quarter-turn electric actuators are built to be workhorses in heavy industrial systems. Designed for use with ball and butterfly valves, they offer a broad range of torques and standard features with a rugged body and gear train for maximum cycle life, the company notes.

The NEMA 4 cast aluminum body of the Series 86 is polyester powder coated to keep environmental elements out. The gear train is made with steel and techno-polymer gears, supported by hardened steel pinions and mounted on self-lubricating bushings for long, reliable service.

Available in six sizes with maximum working torque ranging from 266 to 3,100 in.-lb, they adjust motor speed automatically, depending on load variations. This ensures consistent cycle times. A dome-style position indicator is standard across the range. An electronic torque limiter is also standard. A standard heater is activated when the actuator is powered.

Motors include low voltage 12v and multivoltage 24v ac/dc, 100-240v ac models. Options include programmable positioner, rotary potentiometer, and battery backup for failsafe operation.

 

The new actuators are built to ISO 5211-DIN3337 standards for easy direct mount installation on valves. They are available as separate components or on single-number automated valve packages with Bonomi butterfly valves and low-torque ball valves.

Bonomi North America is part of the Bonomi Group of Brescia, Italy.
