Overview
The MAC Valves 45A-AA1-DAAB-1CA is a direct-acting solenoid poppet valve from MAC’s 45 Series, one of the most widely deployed pneumatic control valves in industrial automation. The 45 Series is a direct solenoid operated 4-way poppet valve featuring a short stroke solenoid, balanced poppet and conical seats, delivering high shifting forces, fast consistent response times, and long life. When configured as a 3-way valve, this model is ideal for single-acting actuator control and applications requiring precise pneumatic distribution.
Key Features
- Patented MACSOLENOID technology provides fastest possible response times with bonded balanced poppets for high flow, precise repeatability and consistent operation
- Balanced poppet design permits versatility in piping—valves can be configured as 4-way, 3-way, 2-way, normally closed, normally open, or for vacuum/diverter/selector applications
- Extremely high cycle rates with extremely long service life due to unique poppet cushions
- Manual override as standard for emergency operation
- Suitable for both lube and non-lube service
