Every year, improper gate valve flange type selection leads to millions of dollars in leakage repairs, unscheduled shutdowns, and compliance fines. If you’re sourcing flanged gate valves for oil & gas, water treatment, or industrial process lines, you’ve likely faced these pain points:
The result? 37% of procurement managers report at least one flange-related field failure per year (2025 Industrial Valve Reliability Report). You don’t have to be that statistic.
At Ningjin Thriveon Valve Co., Ltd., we’ve supplied precision flanged gate valves to over 40 countries since 2010. Our engineers — with a combined century of valve design experience — help you select the right gate valve flange type the first time, every time.
We manufacture to ANSI B16.5 (Class 150/300/600), DIN EN 1092-1 (PN10/16/25/40), and JIS B2220 (10K/20K). Every valve is 100% pressure-tested and traceable.
Need a reduced bore, special facing (RF, FF, RTJ), or non-standard drilling? Our in-house design team delivers custom flange configurations in as little as 15 working days.
Average lead time for standard flanged gate valves: 25–35 days (vs. industry average 60+ days). Air freight option available for urgent orders.
Every shipment includes: material certificate (EN 10204 3.1), pressure test report, NDE report, and flange dimension inspection sheet. Audit-ready.
We consolidate LCL shipments from our Hebei factory to major US ports (LA, Long Beach, Houston) with trusted forwarders. Typical sea freight cost: $0.8–1.2/kg for mixed valve orders.
Our senior engineers provide free flange compatibility reviews — just send your piping spec and we’ll confirm the optimal gate valve flange type within 24 hours.
Select your standard below. All valves are API 598 / ISO 5208 tested with zero leakage at rated pressure.
| Flange Standard | Pressure Class / PN | Size Range | Flange Facing | Materials Available | Typical Application |
|---|---|---|---|---|---|
| ANSI B16.5 | Class 150 / 300 / 600 | 1/2" – 24" | RF, FF, RTJ | WCB, WCC, CF8M, LCB | Oil & gas, petrochemical, power plants |
| DIN EN 1092-1 | PN10 / PN16 / PN25 / PN40 | DN15 – DN600 | RF (Type B), FF (Type A) | 1.0619, 1.4408, 1.4301 | Water treatment, HVAC, chemical |
| JIS B2220 | 10K / 20K | 15A – 500A | RF, FF | SCPH2, SCS13A, SCS14A | Marine, industrial plants, Asia-Pacific projects |
| GOST 12815 | PN6 / PN10 / PN16 / PN25 | DN15 – DN400 | RF, FF | 20GL, 12H18N10T | Oil & gas pipelines (CIS markets) |
| BS 4504 | PN6 / PN10 / PN16 / PN25 / PN40 | DN15 – DN600 | RF, FF | WCB, CF8M, Duplex 2205 | UK & Commonwealth water systems |

ANSI flanges (ASME B16.5) use inch-based dimensions and pressure classes (150, 300, 600). DIN flanges (EN 1092-1) use metric dimensions and PN ratings (PN10, PN16, etc.). The bolt hole patterns are different — ANSI flanges have fewer bolts for the same nominal size compared to DIN. Always verify your piping standard before ordering.
Raised Face (RF) is the most common for general service (water, oil, gas). Flat Face (FF) is used with flat-face companion flanges (typically cast iron). Ring Type Joint (RTJ) is for high-pressure/high-temperature services (Class 600 and above). If unsure, RF is the default for steel flanged gate valves.
Yes. We regularly manufacture JIS B2220 10K and 20K flanged gate valves for US engineering firms working on Asia-Pacific projects. We stock patterns for JIS 10K/20K in sizes 50A–300A. Lead time: 20–30 days.
For standard flange standards (ANSI, DIN, JIS): 25–35 days from order confirmation. For custom flange drilling or non-standard facings: 30–45 days. We offer express production (15–20 days) for orders of 50 units or more — contact us for availability.
Absolutely. Every order includes EN 10204 3.1 material certificate (or 3.2 if required), flange dimension inspection report (bolt hole PCD, flange OD, facing finish), and hydrostatic/pneumatic test certificate per API 598. Third-party inspection (SGS, BV, Lloyds) is available at cost.
We ship FOB Tianjin (base) or CIF to any US port (LA, Long Beach, Houston, Savannah). Typical ocean freight from China to US West Coast: $0.8–1.2/kg for consolidated LCL. We provide a complete commercial invoice with HTS code (8481.80) to simplify customs clearance. Duty rate for steel gate valves into the US is currently 1.7%–3.9% (subject to trade policy).
MOQ for standard flanged gate valves: 5 pcs per size/standard. For custom flange designs: 10 pcs. We can accept sample orders (1–2 pcs) for qualification — sample cost is deductible from your first production order. Request a sample →

"We ordered 80 × ANSI 300 flanged gate valves for a refinery expansion. The flange bolt hole alignment was perfect — not a single valve needed rework. That's a first in my 20-year career."
– David L., Operations Manager, Louisiana Refining
"Thriveon's ability to match DIN PN16 flanges to our existing German piping saved us 6 weeks of re-engineering. Their technical team is world-class."
– Priya M., Supply Chain Director, Chemical Plant, Durban
"The cost savings vs. European suppliers were 42%, with no compromise on quality. We've since made Thriveon our preferred flanged gate valve partner."
