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 plug and seat design
典型应用
steam drains, feedwater branches, condensate systems, sampling lines, and auxiliary services
选型重点
pressure drop, plug and seat design, flow direction, erosion allowance, cycle rate, and handwheel or actuator sizing
