Electric actuated butterfly valve is an automatic device. The electric butterfly valve is driven by the power supply, and then drives the butterfly valve to open and close through the electric actuator to realize industrial automation.
In this article, we will introduce you to how to choose COVNA electric butterfly valve.
COVNA is an experienced and certified manufacturer of valves and actuators. We have a variety of electric butterfly valves, the following are 2 guidelines we provide to help you better choose the right valve with actuator.
1. Electric Actuator
COVNA electric actuators have 5 types, namely part-turn electric actuators, multi-turn electric actuators with gearbox, explosion-proof electric actuators, underwater type electric actuators, and fail-safe type electric actuators for your selection.
Part-turn electric actuator is the normal type actuator. 90 degrees rotation for butterfly valve. It has ON-OFF type, modulating type and intelligent type to help you control locally or remotely. Torque range up to 4,000Nm.
Multi-turn electric actuator with gearbox has a higher torque range up to 10,000Nm. Suitable for the large-size valve or butterfly valve which needs higher torque.
Explosion-proof electric actuator with NEMA4 and 6 protection class. Suitable for hazardous conditions to protect humans safety.
Underwater type electric actuator with IP68 waterproof protection class. Suitable for using underwater.
Fail-safe type electric actuator has a battery. Once the power is off, the battery will drive the valve open or close.
All of those actuators could be controlled by AC/DC power, signal, manual override, or Bluetooth.
