PSRQ641F型气动调节型球阀，是在引进*进技术的基础上进行更新设计，精心制造的产品。采用电磁换向或直接在汽缸内配置弹簧（单作用弹簧复位）及0.4~0.7Mpa气源即可控制阀门角度运转；以压缩空气为动力，实现阀杆带动阀芯在阀体内转动90℃，可以实现全开——全开的转角功能。该产品按其密封性能分为金属密封与软密封。具有结构紧凑、体积精小、运行可靠、密封性好、维修容易、安装方便、适应性强等特点。特别适合于介质是粘稠、含颗粒、纤维性质的场合。可广泛应用于石油，化工、教学设备、轻工、高压设备、制药、造纸等工业自动控制系统中，作远距离集中控制。

Pageno psrq641f type of the pneumatic the ball valve type of course, is to introduce overseas advanced technology based on design, manufacture new products. the inligent control and, with domestic and international name brand electrical the locator supporting, the input signal and 4 ~ 20madc 0.5 ~ 3 7mpa source control anger may, with pressure and flow, temperature, the man waiting for the parameters of adjustment. it is for motivation, to compress air valve stem the core of the body in the 90 O, Can implement the shut - （start- close） open for the regulation of function. the product by the sealing performance into the metal seals and soft sealing. a compact structure, safeand and reliable a small volume, sealed well, easy and convenient service installed, adaptable and other characteristics. particularly suitable for the media is 粘稠, particles, the nature of the occasion. but it is widely used in oil, chemicals, teaching equipment, light and power equipment and pharmaceutical industries, paper, automatic control system, a long distance centralized control 。
