FAQ of 150lb Aluminum Bronze C954 Lug Butterfly Valve
1. Why is C954 aluminum bronze suitable for butterfly valves?
C95400 aluminum bronze offers excellent mechanical strength, wear resistance, and corrosion resistance, particularly in seawater and marine environments. Consequently, it is a preferred material for butterfly valves used in marine vessels, offshore engineering, and other corrosive settings.
2. Can a butterfly valve with a C954 aluminum bronze disc and EPDM seat be used in seawater?
Yes. Both C954 aluminum bronze and EPDM exhibit excellent resistance to seawater corrosion, making them suitable for many seawater and marine piping systems. When selecting a valve, however, one must also consider the materials of other components (such as the stem and fasteners) as well as factors like seawater composition, temperature, pressure, and specific operating conditions. If you are unsure, please contact our team.
3. Which flange standards are compatible with the 150LB Lug butterfly valve?
The 150LB Lug butterfly valve featured here is compatible with ASME Class 150 flanges to meet project requirements.
ZFA also offers butterfly valves compatible with other flange standards, such as PN and JIS; specific bolt hole dimensions and flange standards should be confirmed based on project requirements prior to ordering.
4. Can ZFA customize C954 butterfly valves for marine engineering projects?
Yes. ZFA supports OEM and custom production of butterfly valves. We can customize materials for the valve body, disc, seat, and stem based on the customer’s specific operating conditions and technical requirements, and configure options such as actuation methods, flange standards, actuators, and product markings.
