Frequently Asked Questions (FAQ):
Q1: What exactly does the 3-year extended warranty cover?
A1: The warranty specifically covers defects in materials and workmanship for the valve body and the disc under normal use conditions in marine environments. It is a direct commitment to the longevity of these core pressure-containing components.
Q2: Are these valves suitable for seawater applications?
A2: Absolutely. We offer material combinations specifically designed for seawater service, such as epoxy-coated cast iron bodies with stainless steel discs and EPDM seats, or full stainless steel constructions for highly corrosive duties.
Q3: Can you provide valves that meet specific classification society standards (e.g., ABS, DNV, LR)?
A3> Yes, we can manufacture valves to meet the requirements of major classification societies. Material certificates, NDT reports, and other necessary documentation are available upon request to support your certification process.
Q4: What are the available actuation methods?
A4: We provide a full range: simple lever handles for manual operation, gear operators for larger sizes requiring reduced torque, and electric or pneumatic actuators for remote or automated control integration.
Q5: What is the lead time for standard sizes?
A5: For standard DN50-DN600 valves in common material configurations, typical lead times are 4-6 weeks. Expedited production may be available; please inquire for specific requirements.
Q6: Do you offer a full valve package with actuators?
A6> Yes, we can supply a complete package including the butterfly valve assembled with your choice of electric or pneumatic actuator, limit switches, and positioners, ready for installation.
Q7: How do I select the right seat material?
A7: EPDM is standard for general water service (including seawater) up to 120°C. NBR is suitable for oils and fuels at moderate temperatures. Viton (FKM) is recommended for higher temperatures or more aggressive chemicals. Our team can advise based on your media.
Q8: What are the main ports you ship from?
A8: We primarily ship from Shanghai, Guangzhou, Hong Kong, and Beijing, providing flexible logistics options for our international clients in North America, Europe, Asia, and beyond.
