Frequently Asked Questions (FAQ)
-
Q: What is the difference between a globe valve and a gate valve?
A: A globe valve is designed for throttling and flow regulation, while a gate valve is primarily for on/off service with minimal pressure drop. Our JIS F7305 globe valve provides precise control for applications requiring frequent adjustment. -
Q: Can the valve be used for steam service?
A: Yes, the stainless steel construction (especially 316L) can handle steam up to 350°C. For higher temperatures, we can provide graphite packing and high-temperature seat options. Please consult our engineers for specific conditions. -
Q: Is the Mill Test Report provided for every valve?
A: Absolutely. Each valve is accompanied by a Mill Test Report that certifies the chemical composition and mechanical properties of the material used, traceable to the manufacturer. -
Q: What flanges are compatible with your 10K flanged valves?
A: They are designed to mate with JIS B2210 10K flanges (raised face). If your piping uses other standards like ANSI or DIN, we can supply adapters or customize the flange drilling pattern (please specify when ordering). -
Q: Do you offer valves with other materials like carbon steel?
A: While our standard for JIS F7305 is 304/316L stainless steel, we can manufacture carbon steel versions upon request. Contact us for details. -
Q: What is the lead time for DN50-DN150 sizes?
A: Typical lead time is 15–30 working days depending on quantity. Express delivery options are available for urgent orders. We ship from Shanghai, Guangzhou, Hong Kong, or Beijing ports. -
Q: How does the 1-year warranty work?
A: Warranty covers manufacturing defects in material and workmanship. In case of any issue, we will repair or replace the valve free of charge, with prompt after-sales support from our Shanghai office.
