A fire butterfly valve is specifically designed for fire protection systems. It meets strict standards like UL 1091 and FM 1120/1130, which require the valve to maintain integrity under high-temperature conditions. Key differences include: a fire-safe seat design (soft seat with metal backup), materials rated for elevated temperatures, and quarter-turn operation for rapid closure in emergencies. Standard butterfly valves lack these fire-rated certifications and may fail during a fire event.

Our fire butterfly valve series is engineered to meet UL 1091 and FM 1120/1130 standards. We are currently in the final stage of third-party certification with UL and FM, with full listing expected by Q2 2026. In the meantime, we provide comprehensive test reports, material certificates, and documentation to support your fire marshal approval process. Many clients in the US and Middle East have successfully passed inspection using our valves with the accompanying documentation.

For standard sizes (2"–12") with EPDM seats and ductile iron body, our lead time is 25–35 days from order confirmation. For larger sizes (14"–24") or custom materials, lead time is 35–45 days. We offer an express service (10–15 days) for urgent orders with a 15% surcharge. Shipping via air freight from Tianjin to Los Angeles takes 4–6 days. We always confirm the exact schedule in writing within 24 hours of your inquiry.

Absolutely. We specialize in OEM/ODM customization. Our engineering team can modify: disc material (SS304, SS316, Duplex SS, nylon-coated), seat material (EPDM, PTFE, Viton), flange drilling (ANSI, PN, JIS), actuator mounting (ISO 5211), and special coatings for corrosive or high-temp environments. Minimum order quantity for custom valves is typically 10 units. Send your drawings or specs to info@thriveonvalve.com and we'll respond within 24 hours with a design proposal and quote.

Every fire butterfly valve shipment includes: Material Test Reports (MTR) for all wetted parts, Pressure Test Certificates (hydrostatic shell and seat), Dimensional Inspection Report, Certificate of Conformance (ISO 9001:2015), and a 24-month warranty document. For UL/FM projects, we also provide design verification reports and third-party test data. We maintain full batch traceability with serial numbers on each valve.

Our fire butterfly valves are typically 30–40% lower than comparable US-manufactured or distributed brands (e.g., Victaulic, Nibco, Milwaukee Valve). The savings come from our vertical integration — we cast, machine, and assemble in-house. There are no distributor markups. For a 6" UL/FM-rated fire butterfly valve with gearbox, you can expect pricing in the range of $85–$145 FOB Tianjin, depending on material and quantity. We provide full landed cost estimates for US destinations.

We ship from Tianjin Port, China, via FCL (full container) or LCL (less than container). For urgent orders, we offer air freight to major US hubs (LAX, ORD, JFK). We handle all export documentation, and our logistics team coordinates customs clearance support. Typical shipping cost for a 20' container to Los Angeles is $2,800–$3,500 (as of 2026). We can also arrange DDP (Delivered Duty Paid) terms for qualified buyers.

We accept T/T (bank wire transfer) and L/C (letter of credit) for international orders. For first-time buyers, we typically require 30% deposit with 70% balance against shipping documents. For repeat clients, we offer more flexible terms. We also accept PayPal for sample orders (up to $2,000). All payments are processed through our verified corporate bank accounts.
