(butterfly valve 40mm)
The 40mm butterfly valve is a critical component in fluid control systems, offering precise regulation of liquids and gases across industries. With a compact design and robust construction, these valves handle pressures up to 16 bar and temperatures ranging from -20°C to 150°C, making them ideal for HVAC, water treatment, and chemical processing. Their lightweight build (typically 1.2-1.8 kg) reduces installation costs by 15-20% compared to gate valves, while the quarter-turn operation ensures rapid shutoff, minimizing downtime.
Engineered for durability, 40mm butterfly valves utilize high-grade materials like ductile iron (EN-GJS-500-7) or stainless steel (SS316), achieving a leakage rate of less than 0.1% under ASTM F1172 standards. Advanced seat materials—EPDM for water and Viton for chemicals—extend service life to 10+ years. Key metrics include:
Brand | Body Material | Max Pressure | Certifications | Warranty |
---|---|---|---|---|
ValvTechnik | SS316 | 25 bar | API 609, ISO 5211 | 5 years |
Flowseal | Ductile Iron | 16 bar | AWWA C504, WRAS | 3 years |
Gemü | PP/SS304 | 10 bar | FDA, 3-A Sanitary | 7 years |
Customizable 40mm butterfly valves address specialized needs:
Average 40mm butterfly valve prices range from $85 (standard ductile iron) to $420 (sanitary tri-clamp SS316). However, lifecycle costs show:
Case 1: A German brewery replaced 58 gate valves with 40mm butterfly valves, cutting CIP cycle time by 40% and reducing water usage by 12,000 m³/year. Case 2: A Singaporean wastewater plant achieved 99.97% leak-free operation over 3 years using triple-offset 40mm valves with PTFE seats.
With 78% of engineers specifying 40mm butterfly valves for retrofit projects (2023 Fluid Control Survey), their modular design and compliance with ISO 5211 mounting pads ensure future-proof integration. Partnering with ISO 9001-certified manufacturers guarantees 0.01mm machining tolerances and 100% pressure testing, delivering measurable ROI through reliable performance.

A: A 40mm butterfly valve controls fluid flow in pipelines by rotating a disc. It's ideal for water, air, and low-pressure systems. Its compact design suits industrial and residential plumbing applications.
A: Pricing depends on material (PVC, stainless steel), pressure rating, and brand. Installation accessories and certifications (ISO, ANSI) may increase costs. Bulk purchases typically offer better unit pricing.
A: Temperature tolerance varies by material. Stainless steel valves withstand up to 400°F (204°C), while PVC valves max at 140°F (60°C). Always check manufacturer specifications for thermal limits.
A: Align valve flanges with pipeline using compatible gaskets. Tighten bolts evenly in crisscross pattern to prevent disc binding. Ensure full disc rotation post-installation before system pressurization.
A: Butterfly valves offer quicker operation with 90° rotation vs multiple turns for gate valves. Their compact 40mm design requires less installation space. Maintenance is simpler due to fewer moving parts.
