进口气动针型阀 气控针阀 美国RETZ瑞茨

　　品牌：RETZ/我们一直致力于流体控制和测控领域的持续创新，始于2005……进口气动针型阀采用两截阀杆设计，上阀杆螺纹的润滑脂与系统介质隔离，旋转的下阀杆上下运动代替旋转升降，减低每个过程对填料的磨擦，减少阀座和阀头之间的咬合，阀门在全开位置具有背密封功能，确保工作状态下不会发生泄漏，在相应的温度下密封件不会发生密封不严retz The pneumatic needle valve adopts a two section valve stemdesign. The lubricating grease on the upper valve stem thread is isolated fromthe system medium. The rotating lower valve stem moves up and down instead ofrotating up and down, reducing the friction of the packing during each processand the bite between the valve seat and the valve head. The valve has a backsealing function in the fully open position, ensuring that there is no leakageduring operation and that the sealing element does not leak tightly at thecorresponding temperature
