Bosch Rexroth AS2-SSV-G038-FIA Soft Start Filling Valve

The Bosch Rexroth Aventics AS2-SSV-G038-FIA Soft Start Filling Valve is a pneumatically actuated filling valve from the AS2-SSV family, designed to top up pneumatic lines with a controlled, ramped fill to reduce pressure surges during actuation. This G038-FIA variant uses G 3/8 ports and carries the R412006273 designation, reflecting its configuration that includes a water-quench plate option for steady operation in demanding cycles. The valve features a poppet design with an electrical priority circuit and a true soft-start function that governs the fill sequence with an adjustable filling time (t) and a defined switch-over pressure (p2) in the start function, enabling smooth, gradual pressurization of downstream actuators. Typical applications span sequencing and controlled charging of air reservoirs, cylinders, and pneumatic tools within automation lines where abrupt fills can cause wear or pressure spikes, making it well-suited for reliable, low-stress pneumatic control in industrial systems. As part of Aventics (Bosch Rexroth), this valve integrates with standard air preparation and control schemes, delivering precise, repeatable fill behavior in mid-to-large bore pneumatic circuits.
