Struggling with Valve Failures, High Costs, and Long Lead Times?

  • 💸 High initial cost from local brands – Overpaying for butterfly valves that don’t justify the premium.
  • 🔧 Frequent leakage and short lifespan – Poor sealing materials cause downtime and safety hazards in PN 20 systems.
  • ⏳ Slow delivery from overseas suppliers – Waiting 8–12 weeks for custom butterfly valves disrupts project schedules.
  • 📉 Inconsistent quality control – Batch-to-batch variations lead to rework and unexpected expenses.
  • 📞 Lack of technical support – No engineering assistance for valve selection or installation.
  • 🚢 Hidden shipping & customs costs – Unexpected fees that blow up total project budgets.

Frequently Asked Questions about PN 20 Butterfly Valves

What does PN 20 mean for a butterfly valve?
PN 20 indicates a pressure rating of 20 bar (approximately 300 psi) at ambient temperature. It is a common rating used in European and international piping systems, equivalent to Class 150 in some applications.
Can I use a PN 20 butterfly valve for USA ANSI Class 150 systems?
Yes. PN 20 is generally compatible with ANSI Class 150 (20 bar vs 19.6 bar for Class 150). However, confirm flange drilling and gasket dimensions – we offer dual-drilled flanges to match both standards.
What is the lead time for custom PN 20 butterfly valves (OEM logo, special disc)?
Custom orders typically require 15–25 working days after design approval. Stock sizes (DN50-DN300) can ship within 7 days. For urgent projects, we can arrange partial air freight.
How do you ensure valve quality before shipping?
Every PN 20 butterfly valve undergoes hydrostatic shell test at 1.5× rated pressure and seat leakage test at 1.1× rated pressure. We also offer third-party inspection (SGS, BV) at your cost. CE and ISO 9001 documentation is provided.
What is the minimum order quantity (MOQ) for PN 20 butterfly valves?
MOQ is 10 pcs for standard sizes. For sample orders (1-2pcs) we can accommodate with a small sample fee, refundable on bulk orders. OEM/ODM orders start at 50 pcs.
Do you offer after-sales support and warranty?
Yes. 18-month warranty against manufacturing defects. We provide replacement or refund within 30 days of complaint. Our technical team is available via WhatsApp/email for installation and troubleshooting advice.
How do you handle shipping to the USA? Are there hidden fees?
We ship via FOB Tianjin, CIF to major US ports (Los Angeles, Houston, New York). All costs (export packing, documentation, insurance) are transparently quoted. For DDP we can arrange door-to-door delivery with customs clearance. No hidden fees.
