ASCO™ Series 390 Pressure-Operated Valves
Pressure-Operated Valves 390 ASCO
The ASCO Series 390 are pressure-operated, remote-controlled valves with discs for industrial fluid media.
An anti-water hammer design has fluid entry under the disc for quiet operation. The valves feature long service life in high-cycling applications. A wide range of piston-type operators (63 - 90 -125 mm diameters) are rotatable through 360° for maximum performance at different minimum pilot pressures. The 390 Series is suitable for automotive, bottling, commercial laundry equipment, and heating and cooling circuit applications.
