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.

OverviewThe D943H Stainless Steel Electric Hard-Sealed Butterfly Valve is a valve designed for precise on/off control or regulation of pipeline media. It features a fully stainless steel valve body with a metal hard-sealed structure and is driven by an electric actuator, which enables 90-degree rotary motion of the disc. Utilizing a triple-offset or multi-offset design principle, the sealing surfaces of the disc and the valve seat rapidly separate and re-engage during operation, effectively reducing friction and wear. The transmission mechanism transfers the rotational torque from the electric actuator directly to the valve stem, driving the disc to rotate accurately within the valve body. Both the valve seat and the disc sealing pair are made of high-hardness metal materials, such as stainless steel or hardfaced alloys, and are precision-machined to form a reliable metal-to-metal seal. The D943H Electric Hard-Sealed Butterfly Valve offers high-temperature resistance, high-pressure tolerance, corrosion resistance, and a long service life, making it particularly suitable for demanding applications in industries such as chemical processing, metallurgy, power generation, pharmaceuticals, and food processing.Product drawing of D943H stainless steel electric hard seal butterfly valve

D941X electric flange butterfly valve

Model：
D941X-10/D941X-16/D941X-10Q/D941X-16Q/D941X-10C/D941X-16C/D941X-10P/D941X-16P
Specification：
DN50-DN2000
Pressure：
PN10~PN16
Material：
Cast iron, cast steel, stainless steel + rubber lining, fluorine lining

OverviewThe D941X Flange Electric Butterfly Valve is a type of valve that uses an electric motor as the driving source to control the 90-degree rotational movement of the disc for opening, closing, or regulating the medium in a pipeline. This valve adopts a flange connection method, securely fastened to the pipeline flanges via bolts, ensuring stable and reliable installation. 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

D971F electric fluorine-lined butterfly valve

Model：
D971F-10/D971F-16/D971F-25/D971F-10C/D971F-16C/D971F-25C/D971F-10P/D971F-16P/D971F-25P
Specification：
DN50-DN2000
Pressure：
PN10~PN25
Material：
Cast iron, ductile iron, stainless steel + fluorine lining

OverviewThe D971F Electric Fluorine-Lined Butterfly Valve is a corrosion-resistant valve that utilizes a high-performance fluorine-lining process (polytetrafluoroethylene). It is designed for precise on/off control or flow regulation of corrosive media in pipelines, achieved through 90-degree rotation of the disc driven by an electric actuator. 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

D942X Electric Double Eccentric Butterfly Valve

Model：
D942X-6Q/D942X-10Q/D942X-16Q/D942X-6P/D942X-10P/D942X-16P
Specification：
DN50-DN3000
Pressure：
PN6~PN16
Material：
Ductile iron, stainless steel

OverviewThe D942X Electric Double Eccentric Butterfly Valve is a pipeline control device featuring a double eccentric structure design. Its stem axis deviates from both the centerline of the disc sealing surface and the centerline of the pipeline, forming a unique double eccentric trajectory. This allows the disc to quickly disengage from the valve seat sealing surface upon opening, significantly reducing frictional wear between the sealing pair, lowering operating torque, and extending the valve's service life. The valve utilizes a wafer-type connection, clamped between two pipeline flanges using stud bolts, offering a compact structure and convenient installation. The disc sealing ring employs elastic materials such as NBR (Nitrile Butadiene Rubber) or EPDM (Ethylene Propylene Diene Monomer) to form a soft sealing pair. Driven by an electric actuator rotating the shaft 90°, the valve achieves precise flow regulation and rapid opening/closing. It is widely used in water supply, drainage, HVAC (Heating, Ventilation, and Air Conditioning), and pipeline systems handling corrosive media in industries like chemical engineering.Product Image of D942X Electric Double Eccentric Butterfly Valve

D941W Louver Type Electric Ventilation Butterfly Valve

Model：
D941W-6C/D941W-6P
Specification：
DN500-DN3000
Pressure：
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. This valve is operated by an electric actuator that rotates the shaft 90°, enabling rapid shut-off and continuous regulation of the duct fluid. Accessories such as positioners can be optionally configured for remote automated control.D941W Louver Type Electric Ventilation Butterfly Valve Product Drawing
