Overview
The MAC 225B-611CC solenoid valve is a 3-way, 1/4 inch NPTF pneumatic valve with 24 VDC (8.5 W) coil rating and non-locking recessed manual operator. This model is part of MAC’s 200 Series lineup, engineered for rapid response and extended cycle life in compressed air systems. Ideal for OEMs and maintenance technicians requiring a proven drop-in replacement or primary component for pneumatic control circuits.
Key Features
- 3-Way Valve Design — Provides pilot or direct solenoid control for standard pneumatic applications with flexibility across supply, work port, and exhaust configurations
- Square Electrical Connector — Standard interface for quick electrical integration without custom wiring
- Non-Locking Manual Operator — Allows manual valve actuation for emergency override or testing without electrical power
- Rapid Response & Long Service Life — MAC’s patented MACSOLENOID coil design delivers fast actuation with non-burn-out capability and minimal maintenance downtime
- Port Thread: 1/4 NPTF — Universal porting for standard pneumatic manifold and direct-line installations
- Compact Form Factor — Inline configuration minimizes installation footprint in space-constrained control panels
