■ Overview
The DHCN electric low-noise cage type regulating valve can reduce the noise of compressible fluids. 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. The fluid channel has an S-shaped streamline and is equipped with a guide vane to improve the fluid balance flow around the sleeve, resulting in low pressure drop loss, high flow rate, low noise, anti cavitation, and anti cavitation. The leakage rate of the regulating valve complies with the ANSI Bl6.104 standard.
The product complies with GB/T4213-92 JB/T7387-94。
