8. FAQs on Forged Steel Lift Check Valves

Frequently Asked Technical Questions

Q1: What’s the main difference between forged steel lift check valve and cast steel check valve?
A: Forged steel lift check valve uses hot forging for a seamless, dense body with higher mechanical strength and durability, especially fit for high-pressure/temperature services. Cast steel check valves rely on casting, often resulting in larger, less fatigue-resistant, and potentially porous designs.
Q2: What material standards are commonly used?
A: Industry norms include ASTM A105, A182 F304/316, F11 for forging; casting grades WCB, CF8M. Seats/discs often employ stainless steel or Stellite for corrosion/erosion resistance. Certifications: API 602, API 6D, ASME B16.34.
Q3: Service pressure and temperature ratings?
A: Forged lift check valves are available from PN16 (Class 150) to PN100 (Class 900), temperature range from -196°C (cryogenic) to +560°C (alloy designs), as per ANSI/API/ISO standards.
Q4: How to ensure installation standards?
A: Always install valves per ASME B31.1/B31.3 pipe code, ensuring flow direction, sufficient pipeline support, and avoidance of turbulent upstream/downstream flow. Proper end finishing (flange, BW, SW) is critical.
Q5: What is the typical service life?
A: Lab and field tests confirm >100,000 cycles for forged steel lift check valves (HBYS, Velan), subject to correct media/maintenance; cast variants usually 40,000–60,000.
Q6: Leak, fire-safe, and anti-corrosion certifications?
A: Most premium models, e.g., H41H series, are tested against API 598 (leak), ISO 5208, ISO 10497 (fire-safe), and NACE MR0175 for H₂S/media corrosion compliance.
Q7: Maintenance and onsite support?
A: Leading suppliers like HBYS offer 24/7 engineering hotline, field technician service, and complete DTR-QA traceability (lot/batch/pressure/leak test data) for every valve.

9. Delivery, Warranty, Support

Typical Lead Time: 20–35 working days (stock models faster; customization as per confirmed drawing).
Warranty: 24-month factory warranty (materials/processing defects); extended warranty options for long-term projects.
