Popular Shin Yi Butterfly Valve Lines
Shin Yi offers a variety of butterfly valve designs, suitable for applications ranging from simple manual operation to fully automated systems. The following are the most popular butterfly valve lines from this brand:
Symmetric Shaft Butterfly Valve – WB/FB Series
This is a basic butterfly valve operated manually by lever or gear handwheel, suitable for most standard water and air systems. The valve body is flat and thin, featuring ears (or grooves) on the top and bottom for alignment and clamping between two pipe flanges. These ears are reinforced for durability.
The body surface is coated with epoxy paint for corrosion protection. Inside the body, a black sealing gasket surrounds the valve disc. The valve disc itself has the characteristic shiny silver colour of stainless steel.
Key Features:
- Symmetrical shaft design allows smooth opening and closing with low torque, making it easy to operate.
- EPDM/NBR gasket moulded into the body – provides high tightness and prevents debris jamming.
- Body material: Ductile iron FCD – ASTM A536
- Valve disc: Stainless steel CF8/CF8M, suitable for mildly corrosive environments.
- Sizes: DN50 – DN1200
- Connection types: Wafer or flanged, compliant with BS/JIS/ANSI standards
Suitable Applications: Water supply and drainage systems, wastewater treatment, fire protection (PCCC), HVAC, and both civil and industrial projects.
Electric Actuated Butterfly Valve – EOM Series
This valve series uses an electric actuator to open and close the valve remotely or automatically through a central control system. The valve is designed as a single integrated unit combining the valve body and the electric actuator on top. The valve body is flat and thin, characteristic of butterfly valves, coated with red or blue epoxy paint for corrosion protection and easy identification.
The valve features two pairs of lugs (a total of 4, two on top and two on bottom) with round holes for alignment and clamping between two pipe flanges using through bolts, or flange holes on the sides (for flanged connections). The valve disc is made of stainless steel with its characteristic shiny silver colour.
The control box is a black cylindrical or rectangular unit containing the electric motor, gearbox, and control circuits. It also includes a manual handwheel with spokes and an outer rim with grip, allowing manual operation during emergencies, power outages, or initial setup.
Key Features:
- Operates on AC 220V, AC 380V, or DC 24V
- Supports ON/OFF or Modulating control, with optional Fail-safe function
- Size range: DN50 – DN600
- Torque up to 5000 Nm – ensures stable operation and smooth opening/closing
- Materials: Stainless steel disc, stainless steel shaft, EPDM/NBR or PTFE seat
- Premium epoxy coating – provides excellent corrosion resistance
Suitable Applications: Smart buildings, factories with SCADA/BMS systems, water pumping stations, and automated production lines.

Tips for Choosing the Right Shin Yi Butterfly Valve
To select the most suitable Shin Yi Butterfly Valve for your project, it is important to consider not only the price but also the technical factors and operating environment. The following are some practical tips from Thép Bảo Tín:
Identify the Correct Operating Environment
- Clean water, wastewater, compressed air → choose the WB/FB Series with EPDM or NBR seats, ductile iron body, and stainless steel disc.
- Light chemicals, hot steam, mildly corrosive solutions → prioritise stainless steel 316 discs and PTFE seats for enhanced durability.
- Automated systems → use the EOM Series (electric actuated valves), integrated with BMS or SCADA systems.
Choose the Appropriate Operation Method
- Lever handle: Quick operation, low cost – suitable for DN50 to DN150.
- Gear handwheel (worm gear): Ideal for high-pressure systems or sizes DN200 and above.
- Electric actuator: Integrated for automated systems, remote control, and high-precision requirements.
Check Connection Standards
- Identify your system’s flanges according to BS, JIS, DIN, or ANSI to select the correct wafer, lug, or flanged connection.
- Ensure flange dimensions and face-to-face distances are compatible.
Consider Construction Materials
- Ductile iron (FCD) body: Common, good pressure resistance, cost-effective.
- Stainless steel (CF8/CF8M) disc: Enhanced corrosion resistance, suitable for wastewater or light solvents.
- PTFE seat: Better heat and chemical resistance than EPDM, but at a higher cost.
