Pneumatic Porous Low Noise Control Valve
Porous low noise control valve with sleeve guide and pressure balanced spool. It is a high-performance control valve with dynamic stability and suitable for demanding conditions. Because the working pressure difference is large, the velocity of the medium is fast, causing severe erosion damage to the trim, and it will generate a lot of noise, we changed the window type standard sleeve into a porous sleeve.
