D943WElectric Explosion-Proof Butterfly Valveis composed of a butterfly valve paired with an electric explosion-proof actuator. By inputting control signals (4～20mA or 1～5VDC) and a single-phase power supply, it can be operated. The electric butterfly valve features strong functionality, compact size, lightweight, reliable performance, simple compatibility, and high flow capacity. It is particularly suitable for applications involving viscous, granular, or fibrous media. Currently, this electric regulating butterfly valve is widely used in industrial automation systems across industries such as food, environmental protection, light industry, petroleum, papermaking, chemical engineering, teaching and research equipment, and electric power.D943WElectric Explosion-Proof Butterfly ValveProduct Features:1, Housing: Made of hard aluminum alloy, treated with anodic oxidation and polyester powder coating, offering strong corrosion resistance and an IP67 protection rating.2, Motor: Fully enclosed squirrel-cage motor, compact in size, high torque, low inertia, insulation class F, with built-in thermal protection switch to prevent motor damage.3, Manual Structure: Handwheel design ensures safety, reliability, labor-saving, and compact size. When power is off, manual operation can be performed by engaging the clutch handle.4, Indicator: Mounted on the central shaft with a protruding design to prevent water accumulation and facilitate easy observation.5, Dryer: Prevents condensation inside the actuator due to temperature and weather changes, keeping internal electrical components dry.6, Limit Switch: Dual mechanical and electronic limit. Mechanical limits can be adjusted by rotating screws, ensuring safety and reliability; cam mechanism controls the electronic limit switch, with simple adjustment and accurate positioning.7, Torque Switch: Provides overload protection to prevent motor damage.8, Self-Locking: Utilizes a precision double worm gear mechanism for high transmission efficiency, high torque, low noise (50 dB), anti-reversal, and stable, reliable transmission without the need for additional lubrication.9, Worm Gear: Concave wheel design ensures large contact area with the worm, high transmission torque, balance, wear resistance, and long service life. Of course, the driving and connection methods of this ball valve are not limited to worm gear; they also include flange type, manual type, etc.D943WElectric Explosion-Proof Butterfly ValveDesign Standards:Design Specification: GB/T 12238Structure Length: GB/T 12221Flange Connection: GB/T 9113Testing and Inspection: GB/T 13927D943WElectric Explosion-Proof Butterfly ValveInstallation Dimensions:DiameterDN (mm)Installation Dimensions (Flange)LL1L2HDD1n--ΦdPN10PN16PN10PN16PN10PN16501092701373711651651251254-Φ184-Φ18651122701373731851851451454-Φ184-Φ18801142701373822002001601604-Φ188-Φ181001282701373952202201801808-Φ188-Φ181251412701374072502502102108-Φ188-Φ181501413511404692852852402408-Φ228-Φ222001553511405053403402952958-Φ2212-Φ2325016635814055339540535035512-Φ2312-Φ2630018035814060544546040041012-Φ2312-Φ2635019039014083150552046047012-Φ2316-Φ2640021639014085756558051552512-Φ2616-Φ30
