4′ ′ Ductile Iron Wafer Style Air Actuated Butterfly Valve for Water

  Product DescriptionOverviewAs a component used to cut off the pipeline system and control the flow rate, the centerline butterfly valve has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. The disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is fully open.Features1. Small and light, easy to disassemble and repair, and can be installed in any position.2. The structure is simple and compact, the operating torque is small, and the 90-degree rotation opens quickly.3. The flow characteristics tend to be straight, and the regulation performance is good.4. The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes possible internal leakage points.5. The seal can be replaced, and the seal is reliable to achieve two-way sealing.6. The butterfly plate can be sprayed with a coating layer, such as nylon or PTFE, according to user requirements. Scope  Nominal size2"~48"(DN50~DN1200)Nominal pressureClass 150 (PN6~PN16)Standard:ASME B16.34, API609,EN593Body materialCarbon steel, Stainless steel, Alloy steel, Duplex stainless steelEnd connectionlug, wafer, flange, OperationManual, Pneumatic, Electric, Hydraulic Product Parameters Company ProfileJitai Valve Group is a genuine valve manufacturer.  7000-sqm factory100 employees5+ senior engineers 30+ design patents2 million sets of valves delivered20 million USD annual revenueSince 1988, we have been expert in manufacturing a wide scope of industrial valves including:   Gate valvesGlobe valvesCheck valvesBall valvesButterfly valvesAPI valvesSteam valves High pressure valvesHigh temperature valvesPower Plant valvesOur Advantages  Heavy-duty valve expert with proven expertise in harsh environment;Stringent quality control and traceable reports to provide zero-defect products;Rugged and durable configuration according to API, ASME, BS, JIS, EN standards;All kinds of UG, PRO/E, Solidworks software simulations ensure the efficiency and robustness for tailored components;Complete BV report can be downloaded on our page About us .FAQ1.Q:Are you are a trading company or manufacturer?   A:We are a manufacturer with 7000-sqm factory and 100 employees.2.Q: Can you provide the assembly drawing for confirmation ?   A: Yes, we can give the relavant drawing within 24 hours.3.Q: Can you do non destructive test for valve components ?   A: Yes, we can perform radiographic testing, penetration testing, ultrasonic testing, magnetic particle testing, etc4.Q: How can I vist you when I am in China?   A: We are near the Wenzhou Airport.
