产品详情

了解这款阀门。

结构特点

a compact forged pressure boundary suited to smaller high-integrity lines

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 joint and end preparation

典型应用

refinery drains, vents, bypasses, steam services, and high-pressure instrument connections

选型重点

bore, bonnet joint, end preparation, packing, required NDE documentation, and forging grade
