Dual Plate Double Flanged Check Valve Dimensions — Engineered for Critical Flow Control
Stop guessing on face-to-face lengths, bolt circle diameters, and weight specs. Get ASME B16.5 / B16.10 compliant dimensions with 100% traceability — backed by a decade of export expertise to the USA, Saudi Arabia, South Africa, and Italy.
Why Accurate Dual Plate Check Valve Dimensions Matter More Than You Think
Every year, procurement and engineering teams waste countless hours and budget on valve dimension mismatches. Here are the most common headaches we hear from our customers:
- Face-to-face errors: A 2 mm deviation in the face-to-face dimension (e.g., 60 mm vs. 62 mm for a 2" valve) can cause flange bolt misalignment, leading to catastrophic leakage or line shutdown.
- Bolt circle & hub diameter confusion: Using an ANSI Class 150 dimension on a Class 300 pipeline results in gasket failure and pressure loss — a costly mistake that can exceed $12,000 in rework per valve.
- Weight underestimation: A 10" dual plate check valve can weigh over 95 lbs (43 kg). Wrong weight assumptions lead to inadequate pipe support and safety risks.
- Long lead times for custom sizes: Many suppliers only stock standard dimensions. When you need a non-standard face-to-face or drilling pattern, lead times stretch 8–12 weeks — delaying your entire project.
- Inconsistent quality across batches: Without strict ISO 9001 quality control, dimensions vary from lot to lot, causing field fit-up issues that erode contractor trust.
- Hidden shipping costs: Oversized or overweight valves inflate freight charges by up to 37% — especially critical for air freight or LCL sea shipments to the US and Europe.
The result? Project delays, budget overruns, and strained supplier relationships. But it doesn't have to be this way.

Frequently Asked Questions — Dual Plate Double Flanged Check Valve Dimensions
Q1: What are the standard face-to-face dimensions for a Class 150 dual plate check valve?
Per ASME B16.10, the standard face-to-face dimensions are: 2"=60 mm, 3"=70 mm, 4"=80 mm, 6"=100 mm, 8"=115 mm, 10"=130 mm, 12"=145 mm, 16"=175 mm, 20"=200 mm, 24"=225 mm. Thriveon also supplies Class 300 and Class 600 dimensions on request.
Request our full dimension chart.
Q2: Can you provide non-standard drilling patterns or bolt circle diameters?
Yes. Our CNC machining center supports custom bolt circle diameters, number of bolt holes, and flange facing finishes (125–250 RMS). Simply provide your target flange standard (BS 4504, DIN, JIS, GOST, etc.) or a drawing. Typical lead time for custom drilling is 5–10 working days.
Q3: What is the weight tolerance for your dual plate check valves?
Our manufacturing weight tolerance is ±3% for sizes 2"–12", and ±2% for sizes 14"–24". We provide actual weight on the Certificate of Conformance to help you calculate accurate shipping and pipe loading.
Q4: How do I specify the correct dual plate check valve dimensions for a retrofit project?
Measure these five values: (1) pipe flange O.D., (2) bolt circle diameter, (3) bolt hole size, (4) face-to-face gap between existing flanges, and (5) pipeline pressure rating. Send these to our engineering team and we'll match the replacement valve within 24 hours.
Use our dimension submission form here.
Q5: Do you offer dimensions for bi-directional (dual plate) check valves?
Yes. Our dual plate double flanged check valves are bi-directional standard (spring-loaded plates). Face-to-face dimensions are identical to standard check valves per ASME B16.10. For zero-leakage bi-directional applications, ask about our resilient-seated option.
Q6: What logistics options do you offer for urgent or oversized orders?
We offer FOB (Tianjin/Qingdao), CIF, and DDP delivery. For urgent orders, we can arrange air freight (3–5 days to US East Coast). For large quantities, LCL and FCL sea containers with dedicated loading supervision. We also provide wooden crate packaging with export-grade fumigation (IPPC compliant).
Q7: How can I verify the dimensional accuracy of valves before shipment?
We provide: (1) dimensional inspection report with signed QA stamp, (2) photos/videos of critical dimension measurements, (3) third-party inspection (SGS, BV, TÜV) at buyer's cost, and (4) open for customer or agent factory audit anytime. ISO 9001 ensures full traceability of every dimension check.
Q8: What payment terms do you accept for first-time buyers in the USA?
We accept T/T (30% deposit, 70% against BL copy), L/C (irrevocable, at sight), and for qualified buyers: PayPal (up to $3,000) and Western Union. For first-time US customers, we also offer a
free sample valve (2") with prepaid shipping to evaluate our dimension accuracy and build quality.
