Information About F400B
The F400B is part of Parker’s F Series Colorflow flow control valve lineup, engineered for accurate metering and stable adjustment in general hydraulic applications. It uses a standard metering needle and a fully guided soft seat poppet design to ensure near-zero leakage and smooth reverse free-flow operation. The valve is manually actuated with a standard knob and includes Parker’s Colorflow band indicator for clear visual reference of the flow setting. With female-to-female 1/4" NPT connections, brass construction, and nitrile sealing, it is suitable for factory automation, machine tools, material handling, and industrial fluid control systems.
Key Features:
-
In-Line Flow Control Valve Design: Provides manual metering for hydraulic and pneumatic flow regulation.
-
One-Way Controlled Direction: Allows metered flow in one direction with free reverse flow capability.
-
High Pressure Operation Rating: Supports maximum working pressure up to 2000 psi.
-
Maximum Flow Capacity: Rated for up to 5 gpm (19 L/min) flow control performance.
-
Soft Seat Guided Poppet: Fully guided poppet design minimizes leakage and improves durability.
-
Standard Needle Metering Adjustment: Includes a standard needle for precise and repeatable flow setting.
-
Brass Body Construction: Provides corrosion-resistant performance in industrial fluid applications.
-
Colorflow Visual Indicator Feature: Color-band marking provides accurate visual indication of adjustment position.
The F400B delivers the reliability and precision required for manual hydraulic flow control and industrial metering valve applications.
