RFPN high-performance low-noise single-seat control valve is primarily designed to reduce fluid noise. It is used for throttling, diffusion, and expansion of compressible fluids (such as steam, air, and natural gas). The valve features many small holes arranged regularly on the sleeve to reduce pressure, significantly decreasing noise levels. The fluid channel has an S-shaped streamline, with a flow deflector around the sleeve to improve fluid stability. As a result, the control valve has low pressure drop loss, high flow capacity, low noise, and minimal cavitation corrosion, making it suitable for high-noise environments.
