Pneumatic low-noise cage type regulating valve

Our goal is to become a trusted valve consultant for users. Shanghai Yuhe Valve IndustryPneumatic low-noise cage type regulating valveThere are many symmetrical small holes on the sleeve to reduce pressure drop, which can reduce the noise of compressed fluid. The nominal diameter is DN20-400mm; Nominal pressure: PN16-PN64, ANSI 150-600LB, JIS 10K-40K, valve material: 22052507904L, 1.4529254SMo, titanium, C276， Monel, 304, 316, WCB。

Pneumatic low-noise cage type regulating valveIt is one of the CV3000 series products. In order to adapt to gas throttling diffusion and expansion, the sleeve is equipped with many symmetrical small holes to reduce pressure drop. The valve core adopts a pressure balanced structure, with S-shaped channels and a guide vane to improve 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.
