进口高温高压内螺纹截止阀 锻钢NPT截止阀 美国RETZ瑞茨

　　品牌：RETZ瑞茨/我们一直致力于流体控制领域的持续创新，始于2005……

　　高温高压内螺纹截止阀在管线系统中用于关闭或开启的控制，保持系统正常运行。通过手轮驱动阀杆。阀杆以垂直的方向移动。当顺时针旋转手轮时，阀瓣落下来关闭管线，当逆时针旋转手轮时，阀瓣上升，开启管线 Hightemperature and high pressure internal threaded globe valves are used inpipeline systems to control closure or opening, maintaining normal systemoperation. Drive the valve stem through a handwheel. The valve stem moves in avertical direction. When rotating the handwheel clockwise, the valve disc fallsdown and closes the pipeline. When rotating the handwheel counterclockwise, thevalve disc rises and opens the pipeline

　　密封面不易磨损及擦伤，启闭时阀瓣与阀体密封面之间无相对滑动，因而磨损与擦伤均不严重，密封性能好。Thesealing surface is not easy to wear and scratch, and there is no relativesliding between the valve disc and the valve body sealing surface duringopening and closing, so the wear and scratch are not severe, and the sealingperformance is good
