Features

  • Multi-stage valve cores and porous sleeve structure to gradually reduce fluid velocity, disperse energy, and minimise turbulence and cavitation
  • Noise reduction typically 20-40 dB compared to conventional control valves
  • S-shaped streamline fluid passage with deflector wing for smooth flow around the sleeve
  • Pressure-balanced valve core structure enabling high-pressure-difference control with reduced actuator output force
  • Sleeve equipped with multiple symmetrical small holes to reduce pressure drop
  • Flow characteristics: linear or equal percentage
  • CDN702 dual-directional structure ensures valve stability under high differential pressure
  • RSMF series multi-spring pneumatic diaphragm actuator: compact structure, high output force, long service life
  • Suitable for fluid flow, pressure, temperature, and liquid level regulation

Notes

  • Material list ends with '....' indicating additional materials available on request
  • NPS range stated as 1" to 28" (equivalent to DN25–DN700)

Description

The C700 Series Low-Noise Control Valve comprises the CN702 and CDN702 sub-series, designed to reduce noise in compressible fluid applications. The valve core uses a pressure-balanced structure; the sleeve is fitted with multiple symmetrical small holes to reduce pressure drop, and the S-shaped streamline fluid passage includes a deflector wing to promote smooth flow. The result is low pressure-drop loss, high flow capacity, reduced noise (typically 20-40 dB reduction), and minimised cavitation.
