高压对夹式止回阀是一种超短型止回阀,专为高压管道设计。其通常采用双板(双瓣)或弹簧加载单板设计,阀瓣围绕中心销轴旋转以实现单向流动。与传统法兰旋启式止回阀相比,对夹式的端面长度仅为传统阀门的1/3至1/5,从而重量更轻、安装空间更小,并减少管道负载。.
Forged steel swing check valve
The Forged Steel Swing Check Valve is a compact, high-performance solution designed for small pipeline backflow prevention (DN15-DN50). Featuring precision-forged construction and a lightweight swing disc, it ensures reliable one-way flow control in instrumentation, sampling, and utility systems. This valve operates automatically and is not suitable for flow regulation.
