L22BA452BG17G61 NUMATICS Servo Motor Encoder 24VDC 50(KHz) 0.45kW
L22BA452BG17G61 Description
The L22BA452BG17G61 is a single solenoid-pilot, spring-return pneumatic directional control valve from Numatics (now part of Emerson/Aventics) L2 Series. It features a 4/2 (5-port, 2-position) spool-and-sleeve configuration, designed for factory automation and motion control. Converting electrical signals to pneumatic actuation, it controls double-acting cylinders via CC-Link or hardwired signals. With a compact 1" body width and inline/manifold mounting capability, it suits dense control cabinets and multi-station manifolds (2–12 stations). Rated for high flow and broad pressure ranges, it ensures reliable performance in harsh industrial environments.
L22BA452BG17G61 Key Features
- 4/2 High-Flow Control: 5-port, 2-position spool-and-sleeve design for double-acting cylinder actuation.
- 7olenoid-Pilot & Spring Return: Single 24 VDC solenoid pilot with spring return; flush locking override for manual intervention.
- Space-Saving Form Factor: 1" narrow body for dense inline or manifold mounting (2–12 stations).
- Broad Pressure Range: Main valve: 28" Hg vacuum to 150 PSIG (10 bar); pilot: 14.5–150 PSIG (1–10 bar).
- High Flow Capacity: Up to 79 SCFM @ 80 PSIG (1674 NI/min @ 6 bar) for fast cylinder response.
- 1/4" G Porting: Universal thread for easy integration with pneumatic lines.
- Low Power Coil: 24 VDC, 1.42 W efficient coil with DIN plug-in connection for quick replacement.
- Unlubricated Service: Compatible with unlubricated air systems, reducing maintenance.
- Integrated Diagnostics: Onboard LED indicators for power/actuation status; visible manifold mounting for visibility.
- Robust Construction: Resists vibration, shock, and EMI for reliable long-term operation.
