Structural Features
- Compact Rotary Electric Motor: A rotary-type electric motor with shaft rotation that controls the disc. Features a compact design and powerful performance.
- Aluminum Alloy Motor Housing: The protective motor housing is constructed from anodized aluminum alloy, providing better hardness and force resistance. Additionally, it is treated with a powder coating to prevent static electricity and protect against corrosion, rust, and oxidation.
- Squirrel-Cage Asynchronous Motor with F-Class Insulation: The design incorporates a squirrel-cage asynchronous motor with F-class insulation, which provides thermal insulation and prevents heat transfer to avoid damaging other components within the electric actuator.
- Convenient Mechanical Position Indicator with Glass Cover: A mechanical position indicator is located on top of the electric actuator. The clear glass cover is perfectly sealed to prevent condensation, dust, and water ingress, creating the most favorable conditions for monitoring the open/close status.
- Reliable Chrome-Plated Steel Gear Mechanism: All gears within the electric actuator are made of secondarily treated chrome-plated steel, offering excellent wear resistance, durability, and load-bearing capacity.
- Lightweight and Slim UPVC Plastic Valve Body: The body of the EM-Flow EMEB-OPW Electric Actuated Plastic Butterfly Valve is structured from UPVC material, featuring a compact, slim, and space-optimizing design. UPVC material offers many advantages in terms of durability, corrosion resistance, chemical resistance, and excellent compatibility.
- EPDM Sealing Gasket: The sealing gasket of the Em-flow electric actuated plastic valve is made from EPDM material. A molded gasket mechanism allows for a perfect fit with the valve body, ensuring highly reliable sealing. The high-quality EPDM material provides great durability, good elasticity, and resistance to abrasion and corrosion.
- Standard Wafer Connection: The EM-Flow EMEB-OPW valve features a standard wafer connection, which optimizes the valve’s dimensions, making it much more compact and lightweight than typical flanged types. This connection style is also very secure, with good fastening capability and a high-integrity seal to prevent leakage.
