The imported pneumatic plastic butterfly valve is a valve that controls the opening and closing of the butterfly plate through pneumatic devices, which is mainly composed of valve body, valve stem, butterfly plate, sealing ring and pneumatic device. It is made of lightweight and strong plastic, which is lighter than metal butterfly valves, making it easy to install and maintain. At the same time, the plastic material has a certain toughness and impact resistance, which can withstand the impact of external forces within a certain range and reduce the damage of equipment caused by external forces.
The imported pneumatic plastic butterfly valve is driven by a pneumatic actuator, and the fluid is controlled by changing the position of the piston on the valve body. It has the advantages of fast switching, low fluid resistance, energy saving, etc., and is suitable for a variety of fluid control occasions. In addition, the imported pneumatic plastic butterfly valve has good sealing, which can effectively prevent fluid leakage and ensure the accuracy and stability of fluid control.
Imported pneumatic plastic butterfly valves are widely used in chemical, petroleum, electric power, metallurgy and other industries to control and regulate the flow of media. It has excellent corrosion resistance, can adapt to the erosion of a variety of acids and alkalis and other corrosive media, and ensures the stable operation of the equipment in harsh environments.
Imported pneumatic plastic butterfly valve parameters:
Nominal diameter: DN50mm and DN300mm.
Nominal pressure: pn10mpa～1.6MPa.
Operating temperature range: generally between -29 +150.
Body material: UPVC, CPVC, PP or PP and other plastic materials.
Spool material: UPVC, CPVC, PP or PTFE and other plastic materials.
Sealing material: rubber or PTFE and other materials.
Applicable fluids: suitable for water, gas, oil and other fluids.
Drive mode: pneumatic or electric.
Connection: flange type or clamp type.
The working principle of the imported pneumatic plastic butterfly valve is to use a pneumatic actuator to push the piston to make the valve stem and butterfly plate produce a rotating motion, so as to achieve fluid control. When the pneumatic actuator receives a signal to open or close, the piston compresses the spring, causing a rotational motion of the stem and butterfly plate to open or close the fluid.
The sealing ring of the imported pneumatic plastic butterfly valve is made of high-quality rubber or PTFE and other materials, which can effectively prevent fluid leakage. At the same time, metal-to-metal contact is used between the stem and the butterfly plate, which can ensure the stability and durability of the valve.
The imported pneumatic plastic butterfly valve has the advantages of fast switching, low fluid resistance, energy saving, etc., and is suitable for a variety of fluid control occasions. It is able to achieve precise control of fluids, with high control accuracy and stability.
