Note: All specifications can be adapted to your project's unique flow and installation conditions.
A rectangular butterfly valve is a quarter-turn valve designed for large, non-circular ducts and pipes. It is commonly used in HVAC systems, industrial exhaust, intake air handling, and chemical processing where traditional round valves are structurally inefficient or cannot fit the duct geometry.
Actuator selection depends on the torque required to break the seal, the pressure differential across the valve, and the control signal (binary on/off or modulating 4-20mA). Our engineers will calculate the exact torque for your specific size and pressure conditions. We typically recommend gearboxes for manual shut-off and pneumatic actuators for rapid cycling.
We offer a full range of materials: Cast Iron (GJL-250), Ductile Iron (GGG-40/50), Carbon Steel (WCB), Stainless Steel (CF8/CF8M), and Duplex. The disc (plate) can be specified in SS304, SS316, or Al-Bronze for corrosive environments.
For standard custom sizes (up to 1500mm), our lead time is 4-6 weeks from drawing approval. For very large or specialized valves (e.g., high-temperature alloys), lead time is 8-10 weeks. We offer express production for urgent breakdowns.
We follow a strict QC protocol: incoming material inspection (MTRs), dimensional checks during casting, hydrostatic shell test (1.5x pressure), seat leak test (BS EN 12266), and final visual inspection. We also offer third-party inspection services (SGS, BV) upon request.
Absolutely. We are an experienced OEM/ODM partner. We can cast your logo, apply your specified paint color (RAL), provide customized documentation, and design to your unique performance parameters. Your intellectual property is fully protected.
We accept TT, L/C, and Western Union. Our logistics team can handle all shipping terms (FOB, CIF, DAP). We ship via sea, air, or express (FedEx/DHL). We consolidate small orders to save you freight costs.
We offer a standard 18-month warranty from the date of shipment against manufacturing defects. We provide free replacement parts for any issues related to material or workmanship. Our technical team is available 24/7 for remote troubleshooting.
