这种Y形阀门是一种往下关闭类型截止阀,通过阀座阀瓣行程实现比例开启节流效果。正因如此,Y形阀门成为流量调节应用场合的理想选择。与标准截止阀相比,这种Y形结构能够减少压力损失。可提供国际管道标准IPS通径DN15
~ DN100,承插、SR螺纹、法兰、承插活接头或SR螺纹活接头连接端口的Y形阀门。
The Y-Pattern valve is a closing-down, globe type
valve design that provides proportional opening to seating disc travel.
As such, Y-Pattern valves are ideally suited for flow regulating applications.
The Y-pattern configuration reduces pressure loss over that of standard
globe valves. Available in IPS Sizes 1/2" -
4" with socket, SR threaded, flanged, socket union or SR threaded
union end connectors.
