产品详情
了解这款阀门。
工作原理
a shaft rotates the disc through a quarter turn; seat geometry, differential pressure, flow direction, line velocity, cycle frequency, and actuator torque determine shutoff and control performance; verify post-weld treatment and seat protection during welding
典型应用
steam, high-temperature utility lines, district energy, and long-service welded piping systems
选型重点
weld-end metallurgy, post-weld treatment, seat protection during welding, face-to-face dimension, thermal movement, and NDE
