What Is a Trieccentric pneumatic actuator Butterfly Valve？
The three eccentric butterfly valve finds widespread application across various industries including metallurgy, electric power, petrochemicals, water supply and drainage, as well as municipal construction. It is specifically tailored for use in industrial pipelines where the medium temperature does not exceed 425 ℃.
Featuring a double security structure, this valve conforms to tritec design standards in accordance with API609, BS5155 ANSI B 16.34, and ASME SEC VIII. It serves the dual purpose of regulating flow and breaking fluid within the pipeline.
Constructed from materials such as cast iron, cast steel, and stainless steel, this valve offers durability and reliability in demanding environments. Its non-blind area design ensures minimal friction between the butterfly plate and valve seat, enhancing operational efficiency.

Trieccentric pneumatic actuator Butterfly Valves Features：
- For regulating flow and breaking fluid. Material: cast iron, cast steel, stainless steel
- Non-blind area design: there is almost no friction between butterfly plate and valve seat
- Thin layer valve seat structure, Replaceable seal pair, Balanced fixed structure
- Body seat construction, install the valve seat on the body
The valve incorporates a thin-layered valve seat structure with replaceable seal pairs, facilitating maintenance and prolonging service life. Additionally, its balanced fixed structure and body seat construction ensure stable performance and easy installation by mounting the valve seat directly onto the body.
Technical Parameters of Butterfly Valves：
Air source processor: The pneumatic triplet, a vital accessory for pneumatic valves, combines filtering, pressure reduction, and lubrication functions. The pressure reducing valve adjusts inlet pressure to a stable outlet pressure, utilizing the medium’s energy. In two-piece assemblies, it couples with a filter for compressed instrument air filtering. In three-piece configurations, it adds lubrication to the air, ensuring efficient operation.
Pneumatic solenoid valve: The pneumatic solenoid valve, also known as a directional control valve, is a vital component for regulating the opening and closing of pneumatic valves. It functions by magnetizing and demagnetizing, which directs the gas flow based on voltage signals. Commonly employed to manage gas source and circuit flow, these valves offer precise control over valve operations through voltage signals.
Limit switch: The valve limit switch, also called a travel switch, is a critical field instrument in automatic control systems. It detects the valve’s status and outputs signals for open or closed positions. This switch is essential for confirming and executing subsequent programs by programmers. Additionally, it serves as a vital component for valve interlock protection and remote alarm indication within the system. It effectively indicates and provides feedback on mechanical equipment’s movement limit position.
Valve positioner: The valve positioner is a crucial component of pneumatic control valves, enabling precise control over valve positioning. It utilizes the valve stem displacement signal as input feedback and the controller output signal as the control signal. By comparing these signals, any deviation triggers adjustments to the actuator output signal, ensuring a direct correspondence between valve stem displacement and controller output.
Manual device: The manual device is an essential component that complements the pneumatic actuator assembly. It serves to facilitate manual or pneumatic operation for butterfly valves and ball valves with a 90° opening. This mechanism is crucial for ensuring versatility and flexibility in valve operation, allowing for both manual and automated control as needed.
