Overview
The MAC Valves 912B-PM-111CA is a 4-way, 2-position solenoid valve engineered for precision pneumatic control in industrial automation systems. Part of the proven MAC 900 Series, this valve combines a balanced spool, short stroke with high flow, and both mechanical and air springs for a powerful return force. With 120V AC operation at 50/60Hz, the 912B-PM-111CA delivers reliable performance across diverse industrial applications.
Key Features
- Balanced Spool Design: Series 900 valves are balanced for optimal performance, regardless of pressure
- High Flow Capacity: Single solenoid piloted valve with Cv 1.2 flow coefficient
- Non-Burn-Out Solenoid: Patented MACSOLENOID with non-burn out feature on AC service
- Manual Override: Non-locking recessed manual operator for emergency manual control
- Monostable Operation: Air/spring reset returns valve to neutral on solenoid de-energize
- Minimal Maintenance: No lubrication required (optional medium aniline point lubricant between 180°F and 210°F if used)
Technical Specifications
The 912B-PM-111CA meets demanding industrial standards. Compliant with IEC 615048, IEC 615611, ISO 13849, REACH, Low Voltage Directive (2014/35/EU), and CE marked. The valve is constructed as a piston spool design rated for compressed air or inert gas service.
