Product Content Description:

SCN is a remodel product of SGC. The series are dedicated specifically for low noise and critical anti-cavitation applications on liquid, gas or steam. Unique perforated cylinder plug and multi hole cage control flowing velocities in the valve trims to carry out fluid rationally expand and scientifically arrange pressure grads. The noise level is considerably reduced by 20-30 dBA.
SCN series is particularly effective for modulating compressible fluids at high pressure drop ratios.
