Product Overview
The PARKER N800B is a precision needle valve engineered for accurate flow control and shut-off in industrial hydraulic systems. As part of Parker’s N-series family of flow control and modular valves, the N800B utilizes a fine-threaded, tapered needle stem that advances into a matching seat to provide infinitely adjustable, micrometer-style throttling of fluid flow. This design delivers exceptional metering resolution, making it ideal for applications requiring precise speed regulation of actuators, controlled bleed-off circuits, and reliable isolation of hydraulic lines. The valve is constructed for panel or inline mounting and is compatible with standard industrial hydraulic fluids, offering dependable leak-tight sealing and long service life in demanding operating environments.
