With the continuous expansion of the domestic valve industry, such as PTFE lined valve This type of product has been widely used in many industries. PTFE lined valves, also known as fluoroplastic lined corrosion-resistant valves, are designed to adapt to corrosive environments with strong acids and alkalis. PTFE is lined inside and on the valve plate of conventional butterfly valves to isolate the medium from the valve body and achieve anti-corrosion effects.
The valve body of the PTFE lined butterfly valve adopts a split type combination. Easy to assemble and seal, the valve only comes into contact with the medium when the valve is in operation, with the perfluoroplastic valve seat and the fluorine lined plastic butterfly plate. The inner surface of the valve body channel of the PTFE lined butterfly valve is smooth, with low fluid resistance, high CV value, strong flow capacity, moderate torque, and zero leakage of the medium. The PTFE lined butterfly valve also has dual functions of switching and flow regulation, which can easily open and close the gas path without affecting the flow rate, check valve Ensuring the repeatability of traffic. The slow opening reduces the impact force of instantaneous pipeline pressure on the instrument, and adds a damper, greatly improving the service life of the needle valve. PTFE lined butterfly valves are specifically designed to control corrosive or highly corrosive media. The inner surface of the valve body is covered with various fluoroplastics for selection, suitable for different working temperatures and fluid pipelines. They have the characteristics of high strength and good corrosion resistance.
In order to better adapt to the needs of modern automatic control, PTFE lined butterfly valves can be equipped with electric and pneumatic actuators, and can be controlled by inputting control signals (4~20mADC or 1~5VDC) and single-phase power supply. They can be intelligent (regulating) and switch type. It has strong functionality, small size, lightweight and pleasant, reliable performance, simple matching, and large flow capacity, especially suitable for occasions where the medium is viscous, contains particles, or fibers.
In today's fiercely competitive market, if PTFE lined valve manufacturers want to stand out in the competition, they must accelerate the research and development of valve core technology, continuously innovate and transform products, enhance their market competitiveness, expand development space, achieve product updates, increase product added value, and improve their core competitiveness.
