pneumatic V-type control ball valve

V型阀采用金属硬密封结构，V型阀芯及金属阀座在回转过程中，球芯的V型缺口与阀座做比例流量调节，并且密封面紧密配合，V型口具有强大切断介质、杂质的功能，避免阀门卡死现象发生，并具有自洁功能，因此适用于造纸、化工、冶金等工业企业中含有纤维或微小固体颗粒的悬浊液。配合气动执行器，可以实现90°范围的启闭，跟定位器配套使用可实现远程微电脑控制阀门流量开度，可实现比例调节；与二位五通电磁及控制箱配套使用，可实现开关控制。适用于气体、液体、固态颗粒介质的控制。

V- type of trim with metal seal structure , V- notched and seat do proportion of flow regulation ,and sealing surface works closely when V- spool and metal seat is in rotation process. V- I can cut media and impurities functions to avoid be chocked to death ,and they can self-cleaning function. So this kind of valve can be used in paper making ,chemical ,metallurgical and other industrial enterprises containing fibers or tiny solid particles in suspension.

With pneumatic actuator,it can achieved 90° range of hoist, Working with locator supporting , it can remote microcomputer controlling flow opening to achieve proportion of adjustment; Working with two five-pass solenoid and the control box,it can achieve switches controlling. It can be used for gas, liquid, solid particles,
