DHRM electric low-noise cage type regulating valveOverview: It 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 guiding wing to improve the fluid balance flow around the sleeve, making itLow pressure drop loss, high flow rate, low noise, anti cavitation, anti cavitationThe leakage rate of the regulating valve complies with ANSI Bl6.104 standard. The product complies with GB/T4213-92 and JB/T7387-94.
