With the continuous development of domestic industry, the demand for insulated pneumatic ball valves used on pipelines is also increasing, and the requirements for insulated pneumatic ball valves are also increasing. When users select insulated pneumatic ball valves, they pay special attention to whether the valves have good sealing performance to prevent medium leakage. Due to the good reliability of imported thermal insulation pneumatic ball valve, users often use imported thermal insulation pneumatic ball valve for important parts. However, the imported thermal insulation pneumatic ball valve is expensive, with a long delivery period and inconvenient after-sales service, which seriously affects the operation of the entire pipeline. In order to reduce pipeline costs and realize the localization of thermal insulation pneumatic ball valve, domestic manufacturers also constantly strive to improve the quality and sealing reliability of domestic thermal insulation pneumatic ball valve, and strive to replace the imported thermal insulation pneumatic ball valve.

All hose makers know that this product is also a big one, with a large sales volume. Then customers will choose the right product according to their own industry, and then the needs of this PTFE lined hose in terms of model selection will be well explained! Then the details are as follows:
(1) The profile structure of the valve core is mainly based on the selected flow characteristics, unbalanced force and other factors.
(2) Wear resistance When the fluid medium is a suspension containing high concentration of abrasive particles, the joint surface of valve core and valve seat will be severely rubbed every time it is closed. Therefore, the flow path of the valve should be lubricated and the internal data of the valve should be hard.
(3) Corrosion resistance As the medium is corrosive, the PTFE compensator should try to choose a valve with simple structure when it can meet the conditioning function.
(4) Medium temperature and pressure When the medium temperature and pressure are high and vary greatly, select the valve whose valve core and valve seat data are subject to small changes in temperature and pressure.
(5) Teflon hose is lined to avoid flashing and cavitation flashing and cavitation only occur in liquid medium. In the process of practical consumption, flashing and cavitation not only affect the calculation of flow coefficient, but also constitute vibration and noise, which shortens the service life of valves. Therefore, flashing and cavitation should be avoided when selecting valves.
