Lug type butterfly valve with double-acting/single-acting pneumatic actuated. The valve is equipped with synthetic rubber or EPDM or PTFE seat, which has strong anti-corrosion. Pressure rating can be up to 2.5MPa. Welcome to ODM butterfly valve.
The AW-type cast iron cylinder consists of two separate cylinders, providing a large output torque, low friction coefficient, and flexible rotation, making it suitable for large-diameter valves. The double flanged butterfly valve with pneumatic actuator features a carbon steel valve body and PTFE-lined fluorine valve plate, belonging to the category of mid-line soft-sealed butterfly valves. These valves exhibit excellent corrosion resistance and chemical stability.
Feel free to contact us for customizing AW double-acting or single-acting pneumatic actuators and valves.
Spring return pneumatic butterfly valve made of ductile iron QT450, with a painted appearance and thickened valve body. Lined with PTFE seal and stainless steel 304 valve plate, the anti-corrosion and wear resistance are improved and suitable for acid and alkaline media. The AW type cast iron cylinder is composed of two split cylinders with large output torque, low friction coefficient and flexible rotation. It is suitable for large-diameter valves.
Welcome to contact Fleyenda Flow for customized AW double-acting or single-acting pneumatic actuators and valves.
The pneumatic triple eccentric butterfly valve adopts a precision J-shaped elastic sealing ring and triple eccentric multi-layer metal hard sealing structure. It is widely used in industrial pipelines such as metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction where the medium temperature is ≤425℃. Regulate flow and load-break fluid usage.
The valve adopts a triple-eccentric structure. The valve seat and butterfly plate sealing surfaces are made of stainless steel with different hardnesses. It has good corrosion resistance and long service life. The valve has a two-way sealing function.
The pneumatic flange butterfly valve is simple structure, small size, lightweight, and low cost. This feature is particularly significant for pneumatic butterfly valves, installed in high-altitude tunnels and controlled by a two-position five-way solenoid valve for easy operation. They can also adjust the flow medium.
Pneumatic flange butterfly valves, equipped with pneumatic actuators, have relatively fast execution speed and do not require manual labor, greatly saving human resources and time.
Assembly by the pneumatic actuator and butterfly valve body, controlled conveniently by a 2/5-way solenoid valve. When equipped with a valve positioner, it can also adjust parameters such as fluid flow, temperature, and pressure. The pneumatic flanged butterfly valve has low fluid resistance, and the butterfly lever can rotate 90 degrees to complete the opening and closing.
The flanged pneumatic hard-sealed butterfly valve features a multi-layered metallic hard seal, offering the advantages of elastic sealing and excellent sealing performance at low temperatures.
Due to the nearly equal forces acting on the butterfly plate on both sides of the shaft, and the opposite direction of the generated torque, the opening and closing torque is relatively small, ensuring good sealing under low pressure.
The fluorine-lined flanged pneumatic butterfly valve is specially used to control corrosive or highly corrosive media. The inner surface of the valve body is covered with various fluorine plastics to choose from, which has the characteristics of high strength and good corrosion resistance.
The pneumatic fluorine-lined valve is used in conjunction with the actuator. It has dual functions of switching and flow adjustment. It can conveniently open and close the gas path without affecting the flow rate, ensuring the repeatability of the flow rate. Slow start-up reduces the impact of instantaneous pipeline pressure on the instrument.
It applies to all kinds of acids, alkalis, oxidants, reductants, organic solvents, and other media.
The vertical pneumatic sanitary butterfly valve cylinder is made of whole stainless steel with a polished appearance and high cleanliness for all food and beverage industries. They are adopting the pneumatic driving mode, and driving the valve by compressing clean air so that the circulation and shutdown of the pipeline medium can be strongly controlled.
Tri-clamp, thread, and weld connections are available; welcome to contact us for ODM service!
