Product Description
The vst170 is an overboard valve for aircraft environmental control systems. It routes conditioned air to the atmosphere, helping regulate cabin pressure during automatic or manual pressure control operations. Installed in the outflow path of pressurization systems, this valve discharges excess air to maintain cabin altitude within acceptable limits per FAA 14 CFR 25.841.
The valve integrates with outflow control units and cabin pressure regulators on transport and business aircraft. Installation requires verification against the aircraft's Illustrated Parts Catalog and adherence to manufacturer maintenance procedures.
