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 bonnet extension and flow direction
典型应用
cryogenic storage, LNG vaporization systems, liquid gas transfer, and cold-box auxiliaries
选型重点
minimum temperature, bonnet extension, flow direction, cavity behavior, packing location, and low-temperature test scope
