Frequently Asked Questions (FAQ)
1. Does this valve meet JIS F7305 completely?
Yes, our valve is designed and manufactured in full compliance with JIS F7305 standard, including face-to-face dimensions, flange drilling, and testing requirements.
2. What certifications do you provide?
Standard certificates include material test report, pressure test certificate, and CCS/DNV type approval. Other classification society certificates (e.g., Lloyd's, ABS, BV) can be arranged upon request at additional cost.
3. Can you supply the valve with a handwheel or gearbox?
We offer standard handwheel operation for sizes up to DN150; for DN200 and above, a gearbox is recommended. Both options are available, and we can also provide pneumatic or electric actuators.
4. What is the lead time for DN100 valves?
For standard JIS F7305 sizes, we typically hold stock in Shanghai. Lead time is 2–7 days for small quantities. Larger orders (100+ pieces) require 15–25 days depending on material availability.
5. Is the valve suitable for seawater application?
The cast iron body with standard corrosion-resistant coating is suitable for closed-loop freshwater systems. For direct seawater exposure, we recommend upgrading the seat/ disc material to nickel-aluminum bronze or duplex stainless steel – please consult our technical team.
6. Do you offer samples for testing?
Yes, we provide sample valves with a refundable deposit. After order confirmation, the sample cost can be deducted from the first bulk shipment.
7. What payment terms do you accept?
We accept T/T, L/C at sight, and for long-term partners, negotiable terms. Minimum order quantity is 1 piece for new customers.
