Overview of Small Diameter Low Noise Cage Control Valve
HSNSmall caliber low-noise cage type regulating valve, abbreviated asHSNThe regulating valve isHLCA quick change regulating valve with improved design based on the foundation, mainly suitable for liquid pressure difference exceeding3MPaIn medium pressure applications, it can effectively reduce the noise of compressed fluids and is a high-performance regulating valve. The sleeve adopts a porous structure, which can prevent liquid from flashing and cavitation. Compact structure, with presentationSThe streamlined channel reduces pressure drop loss, increases flow rate, and has a wide adjustable range.
The leakage of the regulating valve meets the requirementsANSI B16.104Standard. The regulating valve is equipped with a multi spring thin film actuator, which has a compact structure and high output force.
This product complies withGB/T4213-92Standard.
