Butterfly Valve

Tianjin Kairun Pump Industry's pump butterfly valves are core equipment developed for precise flow control in pipeline systems, focusing on solving the industry pain points of traditional butterfly valves, such as inflexible opening and closing, sealing failure, and high flow resistance. The products adopt an optimized eccentric butterfly plate design, combined with a precision-machined valve seat, allowing for stepless flow adjustment from 0 to 100%, with a flow resistance coefficient as low as 0.2. Compared to traditional butterfly valves, this reduces energy consumption by 15%-20%, making them particularly suitable for high-flow-rate applications and significantly improving pipeline operating efficiency.

The pump butterfly valves feature a multi-layered upgraded sealing structure, using wear-resistant and aging-resistant materials to achieve bidirectional zero leakage. Suitable for clean water, sewage, industrial circulating water, and mildly corrosive media, these valves prevent safety hazards and economic losses caused by leaks. The valve body is made of high-quality carbon steel or stainless steel, integrally forged and treated with anti-corrosion technology, possessing high pressure resistance, impact resistance, and corrosion resistance. It can operate for extended periods under high pressure and harsh environments, extending its lifespan by more than 60% compared to ordinary butterfly valves.

Our products offer flexible operation, supporting both manual and electric opening and closing modes. The electric model is equipped with an intelligent control module, allowing for remote operation and real-time status monitoring. Lightweight design and standardized flange interfaces ensure easy installation without requiring large-scale infrastructure modifications.

FAQ

Q1: What media can pump butterfly valves handle?

A: Kairun's pump butterfly valves are suitable for clean water, wastewater, industrial circulating water, and mildly corrosive media. Stainless steel versions can handle more corrosive or complex fluids, ensuring durability and leak-free performance.

Q2: What sizes and flow rates are available?

A: Standard sizes range from DN100 to DN500, with maximum flow rates ranging from 150 to 3500 m³/h, meeting the needs of small pipelines and high-flow applications. Please refer to our model list for detailed specifications.

Q3: How are the valves actuated? Manual or electric?

A: Pump butterfly valves support both manual and electric actuation. Electric models are equipped with an intelligent control module for remote operation and real-time valve status monitoring, making them ideal for automation systems.

Q4: How to ensure correct installation?

A: Please check that the valve size, pressure rating, and media type match your piping system. Ensure the flange surfaces are clean and aligned, bolts are evenly connected, and the valve is level. Electric valves should be correctly wired, and the control module should be tested. A pressure test should be performed before full operation.

Q5: How frequently should maintenance be performed?

A: Regular inspection is recommended. Check for smooth operation, abnormal noise, and the integrity of the seals. Clean the valve disc and seat to remove debris or scale. Replace worn or aged seals promptly to prevent leaks. Valves installed outdoors should be protected from direct sunlight and rain.
