The following are the representative application industries of this valve. Since butterfly valves can be applied to almost all industries (as long as the temperature and pressure are in line), many industries have not been listed.
Our CF8M butterfly valve and other stainless steel butterfly valves utilize premium ASTM A351 CF8M/CF8 standard castings. These castings feature precise composition and are completely defect-free, enhancing corrosion resistance by over 300% compared to industry norms, ensuring long-term reliability in aggressive chemical environments.
Our lever operated butterfly valves feature an optimized valve seat structure design, combined with unique vulcanization or embedded processes. This innovative approach achieves a 15% reduction in operating torque and ensures highly reliable, bi-directional zero-leakage sealing, rigorously meeting ANSI/FCI 70-2 Class VI standards for critical applications.
Our flange end butterfly valve are engineered with optimized material ratios and precision surface treatment. This enables them to achieve an exceptional operational lifespan of over 80,000 open/close cycles under complex operating conditions, far exceeding the industry average. As a result, our wholesale stainless steel butterfly valves significantly reduce pipeline network maintenance frequency and overall costs for municipalities.
Our super duplex stainless steel butterfly valves are specifically designed for superior corrosion resistance in harsh seawater environments. They boast an impressive service life of 25 years (compared to an industry average of 8 years), with a corrosion rate reduced by 70%, making them a leading choice for shipbuilders and marine suppliers.
Our SS 316 butterfly valves exhibit an average annual corrosion rate of less than 0.02 millimeters in acidic and alkaline wastewater with pH values ranging from 2 to 12, showcasing exceptional durability in demanding waste treatment processes.
Our stainless steel flanged butterfly valves feature high-precision flange processing, ensuring optimal connection sealing and meeting stringent hygiene standards.
Butterfly valve ss316L with Mo≥2.0% enhances chloride resistance, while duplex stainless steel options provide 50% better erosion resistance for slurry pipelines in mining operations.
Low-torque butterfly valve with locking handle reduces refrigeration energy consumption by 8%, featuring ISO5211 actuator interface for precise positioning and 0.001% leakage rate.
Hand lever butterfly valve in 2507 super duplex withstand high-salinity brine. Hot-shell casting enhances pressure capacity by 20%, certified to ISO 5208 and API 598.
As leading stainless steel butterfly valve manufacturer, we ensure every batch of butterfly valve SS316 undergoes strict material certification, with Mo content ≥2.5% (per ASTM A240).
Our epoxy coated butterfly valves feature HV800+ hardened discs, reducing wear by 50% with copper sleeve bearings (60-70% lifespan extension). OEM-ready for mining slurry systems.
Butterfly valve lever operated with flat-profile handle (ISO 5211 compliant) saves 40% lateral clearance. Multi-position locking optional for tight HVAC ducts.
Stainless butterfly valve with EPDM seals (-30°C rated) and 17-4PH stem ensures leak-free performance in LNG pipelines. EN 12266-1 tested.
Large diameter butterfly valve (DN600+) reduces manual torque by 30% via optimized disc geometry. API 598-certified for rapid closure (<15s) with portable actuators.
As one of SS butterfly valves manufacturers, JRVAL offer Ra≤0.1μm mirror polish, 316L electropolished internals, and SIL3-certified designs to minimize TOC/ion leaching.
Butterfly valve flange type achieves 8-15% lower ΔP via aerofoil disc (ASME B16.34). CE-certified for energy-efficient air handling units.
Butterfly double flange with GTAW-welded 2205 duplex body resists pitting in sewage. 50% rubber-EPDM seats (2-year warranty) prevent jamming.
ATEX II 2G/D-compliant butterfly valve with lever uses 316L conductive stem + grounding kit to dissipate static. SIL3 for gas metering stations.
"Don't waste your time with 'universal' valves if you have mixed pipe standards. We learned that the hard way with constant leaks, a messy plant, and a costly shutdown. JRVAL delivered valves that fit our old DIN pipes and our new ones perfectly. The leaks stopped immediately.Highly recommend."Read the Case: Mismatched Flanges & Failing Valves?

Q: My pipeline’s existing flange is GB standard, but it’s old and may not have standard dimensions. Can your flange match it precisely? |
A: Absolutely. JRVAL’s core advantage lies in “Flange Measurement-Based Customization”. Simply provide precise on-site measurements (e.g., hole spacing, outer diameter, thickness, sealing face type), or let our engineers assist with measurement. We ensure the custom flange aligns perfectly with your pipeline |
Q: We need thicker flanges than standard to enhance connection strength and lifespan. Is this feasible? |
A: Yes. We tailor flange thickness based on chemical industry standards (HG), ASME, or your specific requirements. For stainless steel valves, this customization significantly improves structural stability and pressure resistance |
Q: Can your ANSI B16.5 Class 150 flanges handle highly corrosive media? |
A: Certainly. JRVAL stainless steel flanges comply with ASME, DIN, JIS, and other global standards. We select corrosion-resistant materials (e.g., SS316L, duplex steel) to meet both pressure ratings and corrosive media demands |
Q: Why “retain the original casting surface”? Won’t unpolished surfaces affect hygiene standards? |
A: Our valves use precision casting with naturally smooth surfaces, treated by acid pickling & passivation for cleanliness. For food/pharmaceutical applications, internal mirror polishing is optional. Externally retaining the casting surface demonstrates confidence in quality, avoiding defects masked by excessive polishing |
