Electric Butterfly Valve

Electric butterfly valve is an automated control valve that integrates the butterfly valve body and electric actuator. It is driven by electricity and driven by the internal motor of the actuator to achieve precise rotation of the valve stem and butterfly plate from 0 ° to 90 °, realizing automatic and remote flow regulation or cutoff control of pipeline media. Electric butterfly valves are mainly composed of valve body, butterfly plate, valve seat, valve stem, electric actuator and control unit. According to the sealing form, it can be divided into two types: soft seal and hard seal, which are respectively suitable for conventional medium and low pressure, room temperature working conditions, and harsh working conditions such as high temperature, high pressure, and abrasive media. It can achieve precise positioning by receiving standard control signals (such as 4-20mA, 0-10V, or switch signals) and provide feedback on valve opening status, seamlessly integrating into industrial automation systems such as PLC and DCS. The flange electric butterfly valve, clamp electric butterfly valve, hard seal electric butterfly valve, soft seal electric butterfly valve, high-performance electric butterfly valve, intelligent electric butterfly valve, adjustable electric butterfly valve and other electric butterfly valves produced by Kaiweixi are widely used in the fields of water supply and drainage, HVAC, energy, chemical and environmental protection, and are the core executive components in modern intelligent pipeline systems.

OverviewD943H Stainless Steel Electric Metal Hard Sealing Butterfly Valve is a valve that adopts a valve body made of cast steel, stainless steel, or duplex stainless steel with a metal hard sealing structure, using an electric actuator to drive the disc in a 90° rotary motion to achieve precise opening/closing or regulation of pipeline media. The valve utilizes a triple-eccentric or multi-eccentric design principle, allowing the disc sealing surface to quickly disengage from and engage with the seat sealing surface during opening and closing, effectively reducing friction and wear. Its transmission mechanism outputs rotational torque through the electric actuator, directly driving the stem to rotate the disc precisely within the valve body. Both the seat and disc sealing pair are made of high-hardness metal materials such as cast steel, stainless steel, and duplex stainless steel, forming a reliable metal-to-metal seal through precision machining. The D943H electric metal hard sealing butterfly valve features high temperature resistance, high pressure resistance, corrosion resistance, and long service life, making it particularly suitable for severe service conditions in industries such as chemical, metallurgical, power, pharmaceutical, and food.Product drawing of D943H stainless steel electric hard seal butterfly valve

Upon receiving control signals, the electric actuator transmits the motor's rotational torque to the valve stem through an internal gear drive or worm gear mechanism, thereby driving the attached disc to rotate precisely within the valve body. The disc sealing surface is typically overlaid with elastic materials such as rubber, forming an interference fit with the valve seat on the inner wall of the valve body to achieve bidirectional soft sealing. The D941X Electric Butterfly Valve features simple operation, a high degree of automation, and the capability for remote and intelligent control. It is widely used in water supply and drainage, HVAC, fire protection, power systems, and industrial automation applications.Product drawing of D941X electric flange butterfly valve

The valve features a wafer or flanged connection design, with both the inner wall of the valve body and the surface of the disc completely lined with polytetrafluoroethylene (PTFE) or modified fluoropolymer, providing full flow path corrosion protection. Upon receiving control signals, the electric actuator transfers motor torque to the valve stem via a gear reduction mechanism, driving the disc to rotate precisely within the fluorine-lined seat. The fluorine lining offers exceptional chemical inertness, enabling the valve to withstand a wide range of highly corrosive media, including strong acids, alkalis, and organic solvents. The D971F Electric Fluorine-Lined Butterfly Valve is widely used in the control of corrosive media pipelines across industries such as chemical processing, pharmaceuticals, electroplating, and environmental protection.Product drawing of D971F electric fluorine-lined butterfly valve

Material：
Ductile iron, stainless steel

OverviewD942X Electric Double Eccentric Butterfly Valve is a pipeline control device featuring a double eccentric design, where the valve stem axis is offset from both the disc sealing surface centerline and the pipeline centerline, creating a unique double eccentric trajectory that allows the disc to quickly disengage from the seat sealing surface upon opening, significantly reducing friction and wear between the sealing pair, lowering operating torque, and extending valve service life. The valve adopts a flanged connection, clamped between two pipeline flanges using stud bolts, offering a compact structure and easy installation. The disc seal ring is made of elastic materials such as nitrile rubber (NBR) or ethylene propylene rubber (EPDM) to form a soft sealing pair. Driven by an electric actuator that rotates the stem 90°, the valve achieves precise flow regulation and rapid opening/closing. It is widely used in water supply and drainage and corrosive media piping systems in industries such as water treatment, HVAC, and chemical.Product Image of D942X Electric Double Eccentric Butterfly Valve

D971X electric rubber-lined butterfly valve is an industrial automation execution unit consisting of a high-performance intelligent electric actuator and a center-line rubber-lined valve body. By receiving standard 4-20mA DC analog signals or switch signals from control systems, the actuator provides torque to drive the disc, rotating it within a 0-90 degree range. This adjusts the fluid flow area or achieves tight shut-off in real-time. The body cavity and disc sealing surfaces are fully lined with high-quality elastomers (e.g., EPDM, NBR), providing excellent corrosion and wear resistance while ensuring bi-directional bubble-tight zero leakage at low torque. Due to its compact structure, high flow capacity, and cost-effectiveness, the D971X series is widely used in water supply, sewage treatment, environmental protection, and general industrial fluid control networks.Product Image of D971X Electric Rubber-Lined Butterfly Valve

PN6
Material：
Carbon steel, stainless steel

OverviewThe D941W Electric Circular Louver Type Control Butterfly Valve is a valve designed to control the flow and on/off switching of air or dust-laden gas media through the synchronized rotation of multiple louver-type discs. The stem axis is located at the center of each individual disc. Utilizing a louver-type structural design, the multiple discs are linked via a connecting rod mechanism to achieve synchronized opening and closing. The valve features a flanged connection, meaning both ends of the valve body are equipped with connecting flanges that match the pipeline flange standards, allowing direct fastening to the pipeline flanges using bolts and nuts. The disc sealing pair typically employs a metal-to-metal hard seal structure, offering characteristics such as high-temperature resistance, wear resistance, and corrosion resistance.
