Frequently Asked Questions
What is the operating principle of this butterfly valve?
This valve uses a worm gear actuator that translates handwheel rotation into smooth disc movement. Turning clockwise closes the valve, counterclockwise opens it. The worm gear provides mechanical advantage for easy operation even under pressure.
What are the typical applications for this valve?
It is designed for marine piping systems, industrial fluid pipelines, HVAC, and water treatment. The wafer type design allows installation between flanges, making it suitable for space-constrained areas.
Does this valve have a position indicator?
Yes, the gearbox top includes an integrated position indicator that shows the disc opening angle, allowing visual confirmation of the valve position.
What is the weight of this valve?
The valve weighs 11.2 kg, making it manageable for installation in marine and industrial environments.
