Abstract

An anti-ice system includes a duct that extends from a hot air bleed source to an anti-ice manifold and a direct-acting valve coupled to the duct. The duct may be configured to route hot air from the hot air bleed source to the anti-ice manifold at a regulated pressure and the direct-acting valve may include an inlet portion, a reference chamber, a force-type torque motor, an outlet portion, and a modulating sleeve. The inlet portion may be configured to be in hot air receiving communication with hot air from the hot air bleed source, the reference chamber may be configured to be in hot air receiving communication with the inlet portion, the force-type torque motor may be configured to control a reference pressure of hot air in the reference chamber, and the outlet portion may be configured in hot air receiving communication with the inlet portion via the modulating sleeve.
