Frequently Asked Questions
Q1: What is the difference between a globe check valve and a conventional swing check valve?
A: A globe check valve uses a guided disc that moves linearly along the seat, offering better sealing performance and lower pressure drop in high-temperature applications compared to swing types.
Q2: Can this valve be used for steam service?
A: Yes, the carbon steel body and metal seat are specifically designed for high-temperature steam up to 425°C, meeting the requirements of power plants and marine boilers.
Q3: What flange standards are compatible?
A: The valve is supplied with flanges per ASME B16.5 (Class 400) or DIN PN64. Other standards (e.g., JIS, GOST) are available upon request.
Q4: Is the metal seat replaceable?
A: Yes, the seat ring can be replaced during maintenance. Spare parts can be ordered separately.
Q5: How is the valve tested before shipment?
A: Each valve undergoes hydrostatic shell test at 1.5x rated pressure and seat leakage test per API 598. A test certificate is provided.
Q6: What is the typical lead time for this DN100 globe check valve?
A: For standard orders, lead time is 15–25 working days. Rush orders can be arranged with prior confirmation.
Q7: Do you offer customized trim materials for corrosive media?
A: Yes, we can provide 304/316 stainless steel, duplex, or Hastelloy trims based on your medium and temperature requirements.
Q8: Can you provide a quality certificate?
A: Absolutely. Our ISO9001 certification and material test reports (MTC) are included with every shipment.
