Frequently Asked Questions (FAQ)
Q1: What does "OEM Supply" mean for these marine valves?
A1: OEM (Original Equipment Manufacturer) Supply means we manufacture the valves according to your exact specifications, including design, dimensions, pressure ratings, connection types, and branding. You provide the requirements, and we produce the valves as your contracted manufacturer.
Q2: How does Stainless Steel 316 perform compared to 304 in marine environments?
A2: Stainless Steel 316 contains molybdenum, which significantly enhances its resistance to pitting and crevice corrosion caused by chlorides (like seawater). It is generally considered the preferred material over 304 for demanding marine applications.
Q3: Is GB/T1855 compatible with international standards like ANSI/API or DIN?
A3: While GB/T1855 is a Chinese national standard, its performance requirements for marine valves are robust. Key dimensions like face-to-face and flange dimensions can often be manufactured to align with ANSI, JIS, or DIN standards upon request to ensure global compatibility.
Q4: Can you provide valves with different actuation methods?
A4: Yes, absolutely. We offer a full range of actuation options: standard manual handwheels or gear operators for larger valves, as well as pneumatic and electric actuators for remote or automated control systems.
Q5: What is your typical lead time for an OEM order?
A5: Lead time depends on order quantity, complexity, and customization level. For standard configurations, it typically ranges from 30 to 60 days. We provide a detailed production schedule upon order confirmation.
Q6: Do you offer any surface treatments for additional corrosion protection?
A6: Yes. Standard finish includes passivation for Stainless Steel 316. We can also apply special epoxy coatings or other treatments upon request for applications requiring extra protection.
Q7: What quality control procedures do you have in place?
A7: Our ISO9001-certified system governs every step. This includes material certification, in-process inspections, and final testing such as pressure testing, shell testing, and seat leakage tests as per GB/T1855 or other specified standards.
Q8: What are your main shipping terms and ports?
A8: We primarily operate on FOB, CIF, or CFR terms. Shipments are efficiently handled from major ports including Shanghai, Guangzhou, Hong Kong, and Beijing, offering flexibility for global logistics.
