Pneumatic bellows sealed balanced cage regulating valve

Our goal is to become a trusted valve consultant for users. Shanghai Yuhe Valve IndustryPneumatic bellows sealed balanced cage regulating valveThe upper valve cover adopts a corrugated pipe sealing structure, with a nominal diameter of DN20-400mm; Nominal pressure: PN16-PN64, ANSI 150-600LB, JIS 10K-40K, valve material: 22052507904L, 1.4529254SMo, titanium, C276， Monel, 304, 316, WCB。

Pneumatic bellows sealed balanced cage regulating valveIt is one of the CV3000 series products. The structure is compact, with an S-shaped channel and a guide vane that improves the fluid balance flow around the sleeve, resulting in low pressure drop loss, high flow rate, wide adjustable range, and high precision of flow characteristics.
