Overview
The Parker 7221GBN4VN00A0J322C2 is a pilot-operated, 2-way normally closed solenoid valve rated for 24VDC operation. This brass-bodied valve with NBR seals is engineered for reliable control of air, liquids, gases, and steam in industrial automation, HVAC, irrigation, and fluid power applications. The pilot-operated design allows this valve to handle higher flow rates while maintaining quick response and energy efficiency.
Key Features
- Pilot-operated diaphragm design for smooth, reliable actuation
- 24VDC coil—compatible with standard industrial control systems
- Brass body with NBR (nitrile) seals for broad fluid compatibility
- 2-way normally closed configuration—fail-safe default state
- 3/8″ NPT threaded ports for direct piping integration
- Compact footprint suitable for manifold or inline mounting
