Overview
The Parker 7122KBN2LF00 is a 2-way, 2-position normally open (NO) direct-acting solenoid valve from Parker’s Skinner 7000 series. This industrial-grade valve combines brass construction with PCTFE seals to deliver reliable performance across compressed air, inert gases, water, and light oil applications. With a 24VDC solenoid coil and 1/4″ NPT threaded ports, it integrates seamlessly into pneumatic control systems requiring zero pressure differential actuation.
Key Features
- Normally Open (NO) Design: Valve passes flow in the unpowered state; energizing the coil closes the valve
- Direct-Acting Technology: Operates without pilot pressure; minimal response delay for fast switching
- Flow Factor (Cv): 0.21 Cv for precise flow control in compact systems
- 24VDC Solenoid: Class F coil rated 10W; DIN 43650A / ISO 4400 connector standard
- Versatile Media Compatibility: Air, inert gases, water, and light oil (up to 300 SSU)
- Multiple Mounting Orientations: Preferred vertical upright configuration; can be installed in any position

Typical Applications
The Parker 7122KBN2LF00 is commonly used in:
- Pneumatic control circuits for on/off flow switching
- Compressed air distribution systems and blow-down applications
- Instrumentation and laboratory gas-control panels
- Water or light-oil flow isolation in general-purpose hydraulic systems
- Pilot-supply blocking in larger proportional control manifolds
Compatibility & Replacements
Compatible With
