产品详情
了解这款阀门。
工作原理
a linear stem moves a guided disc or plug toward a stationary seat; the tortuous flow path creates more pressure loss than a gate valve but supports controlled shutoff and, with suitable trim, limited regulation; verify cavitation or flashing risk and alloy grade
典型应用
high-pressure steam, feedwater control bypasses, heater drains, and boiler auxiliaries
选型重点
trim velocity, cavitation or flashing risk, alloy grade, stem thrust, inspection interval, and bonnet seal
