Product Description
SCN is
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 ****0 dBA.
SCN series is particularly effective for modulating compressible
fluids at high
pressure drop ratios.
