Frequently Asked Questions
What sizes do these butterfly valves come in?
Our butterfly valves with center handle actuator are available in sizes from DN50 (2 inches) up to DN300 (12 inches), making them suitable for a wide range of marine piping systems.
What materials are used in construction?
The valve body is available in cast iron or ductile iron, while the disc can be made from stainless steel or aluminum bronze. The seat is made from EPDM, which offers excellent resistance to seawater and provides a tight seal.
Can this valve be used for seawater applications?
Yes, the materials used in these butterfly valves are specifically chosen for marine environments. The combination of a corrosion-resistant disc and EPDM seat makes it suitable for seawater and other aggressive fluids commonly found on ships.
What is the pressure rating?
These valves are rated for PN10/PN16, which corresponds to ANSI 150 lbs. This makes them appropriate for many low- to medium-pressure shipboard applications.
