Frequently Asked Questions
- 1. What is the difference between 10K and 16K in this globe valve?
- 10K and 16K refer to the pressure ratings in JIS standard (approximately 1.0 MPa and 1.6 MPa respectively). 16K valves have thicker body walls and flanges to handle higher pressure. Choose based on your system design pressure.
- 2. Can this valve be used for superheated steam?
- Yes, the cast steel body and metal seat can handle superheated steam up to 425°C (depending on material grade). However, for very high temperature applications, consider optional stainless steel seat overlay.
- 3. What flange standard does your valve comply with?
- Our valve flange facing and drilling comply with JIS B2220 for 10K and 16K ratings. The flanges are raised face type. If you need other standards (e.g., DIN, ANSI), please contact us for customization.
- 4. Do you provide third-party inspection certificates?
- Yes, we can arrange inspection by classification societies such as NK, BV, CCS, or other independent agencies at an additional cost. Please specify your requirement when ordering.
- 5. What is the lead time for DN100 10K valve?
- For standard sizes, typical lead time is 15-25 working days after order confirmation. Larger quantities or special materials may require longer. Please inquire for exact delivery schedule.
- 6. Is this valve suitable for non-steam marine applications?
- The valve is designed for steam, but it can also be used for other high-temperature fluids, compressed air, or oil systems. However, for low temperature or corrosive media, alternative seat/body materials may be recommended.
- 7. How do I ensure the valve size matches my existing piping?
- Our DN sizes correspond to JIS pipe schedule. We recommend providing your flange drilling template or consulting our technical team to confirm compatibility. We can also supply mating flanges and gaskets.
- 8. Do you offer valves with electric actuators for remote control?
- Yes, we can equip the globe valve with pneumatic, electric, or hydraulic actuators as per your automation requirements. Please specify the actuator type and power supply when inquiring.
