Anti-Ice Valves

Anti-ice valves

ANTI-ICE VALVES KEY FEATURES AND BENEFITS • Different functional architectures: THE PERFORMANCE butterfly valves, in-line poppet valves, multi-functional valves FOR SAFER FLIGHTS • Different functions: shut-off, pressure regulation, anti-ice, engine start bleed A wide range of types be pneumatically or electro-pneumatically actuated. They are designed for the • High temperature intake and release of air/pressure to meet your needs • High reliability within the cylinder. • Cost reduction activities on Collins Aerospace has a long heritage Our multi-functional valves can operate all products of supplying anti-ice valves, which in three separate ways and have multiple prevent the build-up of ice in the engine purposes, including: shut-off, pressure • R & D on additive manufacturing cowl and flight control surfaces. Our regulation, engine start bleed and anti-ice. to reduce weight technical solutions include motorized, pneumatically and electro-pneumatically We also offer full system integration • Compact design actuated movement of valves. with our valves by providing: • Easy installation • System modeling and simulation A stainless steel body and graphite seals • Prompt MRO support enable core valve components to operate • Vibration under temperature and pressure operative conditions bleed up to 450° C (842° F). In addition, • Performance testing at system level the inconel body and seals can bleed under full operative conditions up to 650° C (1,200° F). • More than 50 years of actuation We offer a wide range of functional experience architectures for the design of By using a production strategy based anti-ice valves. on Lean principles, we can provide you Our Butterfly valves regulate hot air with low-cost solutions and high on-time around the engine bleed system and delivery performance. Our proprietary can shut off when overheating. These solutions, in-house testing capabilities valves can be motorized or pneumatically and Lean piece-flow production layout actuated. The in-line poppet valves can enable us to offer a large product portfolio to meet your requirements. collinsaerospace.com Anti-ice valves
