⚠️ 2. Incompatibility with existing piping — 34% of procurement teams report that off-spec end connections require additional adapter kits, adding 2–3 weeks to project timelines.
⚠️ 3. High total cost of ownership (TCO) — Import valves from traditional suppliers carry 20–40% price premiums, while low-cost alternatives fail within 8–12 months.
⚠️ 4. Inconsistent quality across batches — Without strict QA processes, connection dimensions vary, causing assembly headaches and safety risks on site.
You need a wafer butterfly valve with a precision-machined end connection that meets API, ISO, and ANSI standards — delivered on time, at a fair price, with full traceability.
Our wafer type butterfly valve features a fully machined end connection that guarantees 100% flange alignment, zero leakage, and rapid installation. Backed by 10+ years of export experience to the USA, Saudi Arabia, South Africa, and Italy.
CNC-machined flat face with a surface roughness of Ra ≤ 3.2 µm ensures a perfect gasket seal. No shims, no rework.
Designed to ANSI B16.5 / B16.47 and EN 1092-1. Fits seamlessly with PN10/16, Class 150/300 flanges — no adapters needed.
Every valve undergoes shell and seat testing per API 598. Zero leakage guaranteed at 1.1× rated pressure.
Stock items ship in 7–10 days. Custom end connection sizes available with 15–20 day lead time.
CE, ISO 9001, and RoHS certified. Meets FDA and HACCP requirements for food-grade applications.

A wafer type butterfly valve end connection is the interface that fits between two pipe flanges using a centering alignment. It does not have a full flange face — it is a compact, lightweight design that is clamped between flanges with bolts passing through the valve body’s holes or lugs.
We provide a full dimensional drawing with every quotation. Our standard end connections match ANSI B16.5 Class 150/300 and EN 1092-1 PN10/16. Simply tell us your flange standard, size, and pressure rating — we’ll confirm compatibility within 4 hours.
Yes. Our OEM/ODM service allows custom face-to-face dimensions, bolt hole patterns, and special groove or tongue finishes. Minimum order quantity for custom end connections is 50 units. Lead time: 20–25 days.
We accept T/T bank transfer, L/C at sight, and Western Union. For first-time buyers, a 30% deposit with 70% balance against copy of shipping documents is standard. Open terms available after 3+ repeat orders.
We follow a strict ISO 9001 quality management system. Every production lot is inspected for end connection dimensions (CMM), pressure integrity (API 598), and material composition (PMI). A full inspection report is included with each shipment.
Shipping to major US ports (Houston, Los Angeles, New York) is typically $300–$900 for a 20′ container, depending on volume. Delivery time: 25–30 days by sea. Express air freight (7–10 days) available for urgent orders.
Yes. We provide a 36-month warranty against manufacturing defects in the end connection, including leakage at the flange interface. Free replacement or refund issued within 24 hours of claim approval.
“We ordered 480 units for a desalination project. The end connection dimensions were spot-on with our ANSI flanges. No leaks during hydrotesting. Thriveon’s quality is as good as any European brand — at 40% less cost.”
“I was skeptical about importing valves from China, but Thriveon sent a free sample that we tested for 3 months. The end connection fit perfectly, and the EPDM seat showed zero wear. We now use them exclusively.”
“High-quality ductile iron body with accurate end connection drilling. We installed them on a high-pressure slurry line — 12 months in, no issues. Thriveon’s technical support team also helped us choose the correct seat material.”
“We needed FDA-compliant butterfly valves for our food production line. Thriveon provided full material certification and HACCP documentation. The wafer end connection design allowed quick retrofit without pipe modifications.”
“We compared quotes from five suppliers. Thriveon offered the best balance of price, certification, and delivery. The end connection alignment was within 0.1 mm tolerance. Only suggestion: include more bolt hole options in the standard range.”
