Electric Wafer Butterfly Valve: The Versatile and Economical Choice for Flow Control
The electric actuated wafer butterfly valve is a cornerstone of modern industrial and commercial piping systems, celebrated for its simple, reliable design and exceptional economic value. This valve is engineered to provide efficient on/off and throttling control for a wide array of fluids, including water, air, gas, and other compatible media. Its defining feature is the compact wafer-style body, which is designed to be easily installed between two pipe flanges. When paired with a robust and reliable electric actuator, this wafer butterfly valve becomes a powerful tool for automation in applications ranging from HVAC and water treatment to general industrial services. With its lightweight construction, low-torque operation, and excellent flow characteristics, it stands as a preferred choice for engineers and operators seeking dependable performance and ease of use.
Core Advantages & Features
Compact, Lightweight Wafer-Style Design
The wafer butterfly valve features a streamlined and minimalist body design that allows it to be “sandwiched” between two existing pipe flanges, secured by long bolts that run from one flange to the other. This innovative configuration offers several key advantages. It makes the valve exceptionally lightweight and compact compared to traditional flanged or lug-style valves, which simplifies handling and significantly reduces installation time and cost. The smaller footprint is ideal for systems where space is limited, and the reduced material usage makes it a highly cost-effective solution without compromising performance.
Durable and Reliable Construction
Built for longevity, this wafer butterfly valve is available with a body and disc made from robust materials including Ductile Iron, Cast Iron (CI), WCB Carbon Steel, and Stainless Steel (SS). Ductile iron, in particular, offers superior strength and impact resistance compared to standard cast iron, ensuring durability in demanding industrial environments. The valve incorporates a high-strength, one-piece stainless steel stem, providing a reliable connection to the electric actuator and ensuring consistent torque transmission for smooth and dependable operation.
Excellent Sealing and Flow Characteristics
At the heart of the valve is a resilient seat, which provides a bubble-tight seal when the valve is in the closed position. A wide range of seating materials is available, including NBR, EPDM, VITON, and PTFE, allowing the valve to be configured for various temperatures and chemical compatibilities. The valve features a simple structure with a midline design, which contributes to its excellent sealing capabilities and efficient performance. Hydraulically, this wafer butterfly valve is highly efficient, boasting a low flow resistance coefficient and flow characteristics that tend towards a straight line, making it suitable for both on/off and basic throttling control. Its design also ensures that it will not retain debris, a crucial feature in water and sewage applications.
Powerful and Versatile Electric Actuation
This wafer butterfly valve is paired with a high-performance electric actuator for seamless automation. The actuator is housed in a hard aluminum alloy body with an IP65 protection rating, making it resistant to dust and water ingress. A key benefit of butterfly valves is their low driving torque requirement, which allows for the use of more compact and energy-efficient actuators. The actuator’s self-locking gear train ensures the valve disc remains stable in its set position. For advanced process control, Regulation or Intelligent type actuators are available, capable of responding to 4-20mA or 0-10V signals for precise flow modulation.
Broad Industrial and Commercial Applications
The versatility and reliability of the electric wafer butterfly valve make it suitable for a vast range of industries and systems, including:
Water supply and drainage
Sewage and wastewater treatment
HVAC and heating systems
Hydropower and energy systems
Metallurgy and textile industries
Food processing
Shipbuilding and marine applications
