At a glance:

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.

Features:

High flow capability
Back pressure resistant
Maintenance-free actuators
Satisfies Pressure Equipment Directive 2014/68/EU, category 1 (DN > 25) or article 4.3 (DN ≤ 25)
