Frequently Asked Questions
What materials are used in this butterfly valve?
The valve body and disc are made of high-quality ductile iron or stainless steel (depending on variant), with a resilient seat material such as EPDM or NBR for reliable sealing. Please contact us for specific material options.
Is the valve suitable for seawater applications?
Yes, with appropriate material selection (e.g., ductile iron with epoxy coating or stainless steel), this valve can be used in seawater systems. Confirm the specific material compatibility with your application.
What is the operating torque for the hand wheel?
The worm gear actuator reduces operating effort significantly. For a DN65 valve, the required torque is low and can be operated manually without tools. Exact torque values are available upon request.
Does the valve come with mounting hardware?
The valve is supplied as a complete unit with the worm gear actuator. Flange bolts and gaskets are not included and should be sourced separately based on your flange standard.
