Actuation Types


Manually Operated Butterfly Valve

Offering manual butterfly valve in handle operated type and gear operated type to meet your valve needs. We could help to print the logo on the handle!


COVNA Electric Actuator

We offer quarter-turn electric actuator in on/off type, modulating type and intelligent type to allow you to control the valve remotely.

  • On/off type: For fully open and close within 90 degrees.
  • Modulating type: For regulating the switch angle of the valve from 0 degrees to 90 degrees. It could receive the signal(4-20mA, 1-5V, 0-10V) then you could regulate the valve remotely. Meanwhile, it could feedback the signal which could allow you to check the valve position.
  • Intelligent type: For regulating the open/close angle of the valve. It also could receive and feedback the signal to help to control remotely. What’s more, it has an LCD display screen which could allow you to control it locally.

Besides, a multi-turn actuator with gearbox is available for the butterfly valve which requires higher torque. Explosion-proof actuators, IP68 underwater actuators, fail-close actuators and fail-open actuators are available for your special needs.

All of our electric actuators have a manual override which could allow you to open or close manually while power off.


Pneumatic Valve Actuator

We manufacture pneumatic valve actuators in single-acting type and double-acting type to meet your actuation needs.

  • Single-acting type: Supply air to open the valve, and the valve could auto-return when air is interrupted
  • Double-acting type: Supply air to open, and supply air to close

Offering all types of pneumatic accessories to help you to control automatically. Like switch box, positioner, gearbox, directional control valve and F.R.L
