VFR 凸輪撓曲調節閥是一種結構新穎的調節閥。閥芯的回轉中心不與旋轉軸同心，可減少閥座磨損，延長使用壽命：閥芯后部設有一個導流翼，有利于流體穩定流動，具有優良的穩定性。其次，還有流量大，可調范圍廣的優點。調節閥的泄漏量符合ANSI B16.104 標
準。
本產品符合GB/T4213-2008 標準。
Cam Flexing Control Valve
VFR Cam flexing control valve has a novelty construction. The gyration centre of plug is not concentric with revolving shaft, which can be decrease seat abrasion and extended service life. There is a diversion ala in the back of the plug in favor of steady and large flow and wide adjustable extent. The seat leakage of the valve complies with ANSI B16.104 standard.
The product is designed according to GB/T4213-2008 standard.
