The function of the actuator is also important. Engineers must consider the torque required, rated duty cycle, movement rate, inputs and outputs available for control, materials, IP or NEMA rating, and cost. 

Bonomi North America’s new range of heavy-duty explosion-proof electric actuators are for use in NEMA 4X, 7, 8 and 9 applications.

Geberit’s Sigma70 dual-flush actuators feature smooth, seamless surfaces and a rimless design.

Uponor’s thermal actuator for stainless-steel manifolds completes the actuator offering for radiant heating and cooling manifolds.

Bonomi North America’s Valbia VB008 mini quarter-turn direct-mount electric actuator measures 4 3/4” long x 2 3/4” wide.
