This is not just a mechanical device; it is a comprehensive automation solution that delivers exceptional precision, stability, and economic efficiency, trusted by leading engineers and plant managers worldwide.
Join us as we delve deeper into this “masterpiece” from Taiwan and discover why it is the perfect component for your company’s success.
EMEB-OSW Electric butterfly valve – The perfect fusion of mechanics and technology
emeb-osw electric butterfly valve – the perfect fusion of mechanics and technology
To fully grasp the power of this product, we need to break down its core components:
Butterfly Valve: A valve with a quick open/close mechanism, requiring only a 90-degree turn of the disc. Its simple, compact, and lightweight design makes it easy to install and saves space compared to other valve types like gate valves.
Stainless Steel (Inox): The “gold standard” material in the industry. The valve is crafted from high-grade stainless steel (typically SUS304 or SUS316), offering excellent resistance to chemical corrosion and rust, withstanding high temperatures and pressures, and ensuring sanitary safety (crucial in the food and pharmaceutical industries).
Electric Actuator: This is the “brain” of the valve. Instead of a manual lever or handwheel, the valve is controlled by an electric actuator (motor). This actuator receives electrical signals to perform opening, closing, or flow regulation tasks completely automatically, accurately, and can be integrated into a central control system (PLC, SCADA).
EM-Flow Taiwan: A reputable brand specializing in high-quality automation equipment and industrial valves from Taiwan. EM-Flow products are known for their advanced technology, outstanding durability, and competitive pricing, making them a smart choice for investors.
In summary: The EMEB-OSW Electric Stainless Steel Butterfly Valve is an automated industrial valve that uses an electric motor to control a stainless steel disc, enabling precise, fast, and reliable opening, closing, or regulation of fluid flow within a pipeline.
Why hy choose em-flow? The secret behind taiwanese quality
The market offers countless options, so why has the EM-Flow brand earned the trust of the most demanding customers?
Modern Manufacturing Technology: Taiwan has long established itself as one of the world’s high-tech manufacturing hubs. EM-Flow inherits this legacy, applying automated production lines and strict quality control processes compliant with international standards (ISO 9001), ensuring every product leaving the factory meets the highest standards of precision and finish.
Premium Materials: EM-Flow is committed to using standard-compliant stainless steel, ensuring both corrosion resistance and mechanical strength. The electric actuators are assembled from high-quality electronic components, offering long service life and stable operation in harsh industrial environments.
Optimized Design: Every detail of the valve is relentlessly researched and improved by EM-Flow’s engineers—from the hydraulically optimized disc design that reduces pressure loss, to the high-grade sealing seat (made from EPDM, PTFE, Viton) that guarantees a perfect seal.
Excellent Value for Money: Compared to products from Japan or G7 countries, EM-Flow valves offer a much more reasonable price point while maintaining nearly equivalent quality. This represents a smart investment that optimizes initial costs without sacrificing performance and reliability.

stainless steel valve body
Electric actuator section
Brand: EM-Flow (or other Taiwanese brands like Haitima, Unid).
Model: EM-Series…
Voltage: 24V DC, 220V AC, 380V AC (1-phase or 3-phase).
Control Type:
ON/OFF: Fully open or fully closed. This is the most common type.
Modulating (Regulating): Controls the valve to open at various angles (from 0-90 degrees) via an analog signal (4-20mA or 0-10V). This type is used for precise flow rate control.
Ingress Protection Standard: IP67, IP68.
IP67: Fully dust-tight and capable of withstanding immersion in 1 meter of water for 30 minutes. Ideal for outdoor and humid environments.

The 9 golden benefits of investing in EMEB-OSW electric stainless steel butterfly valves
Translating technical features into real-world benefits for your business:
Comprehensive Automation: Minimize human intervention, eliminate operational errors, enable remote control, and integrate seamlessly into central monitoring systems.
Unmatched Durability: SS304/316 material provides complete corrosion protection, ensuring long-lasting performance in the harshest environments, from chemical plants to seawater treatment systems.
Absolute Precision Control: The electric actuator ensures the valve opens and closes to the exact position at the right time. With modulating control, flow is regulated with milliamp-level accuracy.
Optimized Labor Costs: A single operator in a control room can manage hundreds of valves, freeing up personnel for higher-value tasks.
Energy and Material Savings: The perfect, leak-free seal conserves fluids and preserves energy (heat, pressure) within the system.
Maximum Workplace Safety: Reduces risks for workers who would otherwise have to operate valves in high, low, or hazardous locations with extreme temperatures or toxic substances.
Flexible and Easy Installation: The compact design and international connection standards make installation and replacement quick and simple.
Near-Zero Maintenance Costs: The simple construction, durable materials, and reliable actuator significantly minimize the need for periodic maintenance and repairs.

Expert guide: How to select the right valve
To choose the perfect product and optimize costs, you need to answer these five questions:
What is your fluid/medium? (Clean water, wastewater, chemicals, food products…). This determines the material for the body, disc, and especially the seat.
What are the operating temperature and pressure? These parameters help select a valve with the appropriate rating (PN10/PN16) and the correct seat material.
What is your pipe size? Choose the valve size (DN) that corresponds to your existing pipeline.
What type of control do you need? Do you simply need to fully open/close the line (choose ON/OFF), or do you need to regulate the flow rate precisely (choose Modulating 4-20mA)?
What is the available power supply? Select an actuator with the correct voltage (220V, 24V, 380V).
If you’re still unsure, don’t hesitate! Our team of engineers is always ready to provide a free consultation to help you select the exact product for your needs.
