Your Challenges

Does Your Current Check Valve Cost You Dearly?

Every minute of downtime in a 48-inch pipeline or a high-pressure HVAC system burns thousands of dollars. If your existing dual plate check valve fails to close swiftly, you face:

⚠ Water hammer surges Pressure spikes up to 10x working pressure → pipe fatigue & rupture

⚠ Unplanned maintenance every 3 months Replacements, seal failures, labor costs > $4,200 per incident

⚠ High shipping & import delays Overseas suppliers with 8–12 week lead times & unpredictable freight

⚠ Inconsistent quality & certification gaps Valves that fail hydrostatic tests, missing API/CE marks

Result: Over 60% of procurement managers in our 2025 survey admitted that poor check valve performance triggered at least one emergency shutdown in the past year. You don't have to live with that risk.

Frequently Asked Questions

All You Need to Know About Dual Plate Check Valve Double Flanged

What is the difference between a wafer and a double flanged dual plate check valve?

A wafer type sits between flanges and requires longer bolts, while a double flanged valve has integral flanges that bolt directly to pipeline flanges. The flanged version offers better stability for larger sizes (≥12") and higher pressure classes, and simplifies maintenance because you don't need to disassemble the entire joint.

Which standards do your double flanged dual plate check valves comply with?

Our valves are designed to API 594 (face-to-face) and tested per API 598. We also offer options meeting BS 5153, EN 558, and ASME B16.5/B16.47 flanges. Certificates of compliance and material traceability are included with every shipment.

What is the typical delivery time for a double flanged dual plate check valve?

For standard sizes (2"–12", Class 150/300), we keep inventory in our Ningjin factory and can ship within 7–14 business days. Custom sizes or exotic materials (Duplex, Inconel) typically take 4–6 weeks. We also offer air freight for emergency orders.

Can I get a free sample or prototype before bulk order?

Absolutely. We provide free samples for qualified projects (up to 4"), with the buyer covering shipping. For larger samples, we offer a 100% refundable deposit that is deducted from your first production order. Contact us with your application details.

How does Thriveon control quality across large batches?

Every valve undergoes 100% hydrostatic shell and seat testing. We randomize shell hardness, thickness checks, and NDE (PT/MT) per your specification. Our ISO 9001:2015 system and third-party inspection (SGS, Bureau Veritas) are available at your cost.

What warranty do you offer on double flanged dual plate check valves?

We provide a standard 18-month warranty from the date of shipment. This covers defects in materials and workmanship. Extended warranties (up to 5 years) are available for critical applications — ask our sales team for details.

Do you offer certificates for the US market (CRN, NSF, UL)?

We can supply valves with CRN registration for Canada, NSF/ANSI 61 for potable water (upon request), and material certifications to ASME Section II. UL/FM listings are available on selected models. Our team will walk you through the certification process for your state.

What Our Customers Say About Us

Robert Chen
Piping Supervisor, SoCal Water District

"We installed 6x 36-inch double flanged check valves from Thriveon in a flood control project. Zero leaks, and the coating withstood brackish water perfectly. Will order again."

Linda Jacobsson
Project Manager, Nordic Process AB

"We were skeptical about a Chinese supplier, but Thriveon's samples arrived with full documentation and passed our Swiss testing lab. The price was half of our usual supplier."

Ahmed Al-Rashid
Plant Engineer, Aramex Petroleum

"The duel plate check valves arrived 2 weeks earlier than quoted. Our team installed them on the 16" crude line without any issues. Very smooth operation."
