DELCO 多圈防爆片式電動蝶閥
The explosion-proof motorized butterfly valve can be controlled using switch signals or control signals and a single-phase power supply. This valve is noted for its strong functionality, compact size, lightweight, reliable performance, simple integration, and high flow capacity. It is especially suitable for various liquids, gases, steam, and mediums that are viscous, contain particles, or have fibrous properties.
This explosion-proof electric control butterfly valve is widely used in industrial automation control systems across various industries, including food, environmental protection, light industry, petroleum, papermaking, chemical, educational and research equipment, and power.
型號： Explosion Proof Electric Butterfly Valve
尺寸範圍： 2″ to 40″
壓力範圍： 1.0 to 1.6MPa
材質： Cast Steel, Cast Iron, Ductile Iron or Stainless Steel
Electric Explosion-Proof Actuator Features
- Housing: The housing is made of hard aluminum alloy, with anodic oxidation treatment and polyester powder coating, contributing to its strong corrosion resistance. It has a protection class of IP67, NEMA4 and 6, and is also optional for IP68 and the explosion-proof type.
- Motor: The fully enclosed squirrel-cage motor has a small size, a large torque and a small inertia force, with an insulation class F and a built-in thermal protection switch to prevent damage to the motor caused by overheating.
- Indicator: The indicator is mounted on the central shaft and used to observe the valve position. The mirror adopts a convex lens design with no water accumulation, thus easier for observation.
- Limit Switch: Mechanical + electronic limit. The mechanical limit screw is adjustable, being safe and reliable. The electronic limit switch is controlled by the cam mechanism, and the position can be set accurately and easily just by means of adjusting the mechanism simply, without battery support (All micro-switch contacts are silver contacts).
