Hydraulic Manifold

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Hydraulic Manifold used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Hydraulic Manifold is characterized by the integration of Inlet Port and Outlet Ports. In industrial production environments, manufacturers listed on CNFX commonly emphasize Carbon steel construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A hydraulic component that distributes fluid flow from a single source to multiple circuits within a quick coupler system.

Product Specifications

Technical details and manufacturing context for Hydraulic Manifold

Definition
The hydraulic manifold in a quick coupler serves as the central distribution hub that routes hydraulic fluid from the power source to various functions such as locking/unlocking mechanisms, pressure regulation, and safety systems. It integrates multiple valves, ports, and passages into a compact block to minimize leaks and simplify maintenance.
Working Principle
Hydraulic fluid enters the manifold through an inlet port and is directed through internal passages to multiple outlet ports. Valves within the manifold control flow direction, pressure, and volume to operate different functions of the quick coupler simultaneously or sequentially.
Common Materials
Carbon steel, Stainless steel, Aluminum alloy
Technical Parameters
  • Port thread size and spacing dimensions (mm) Standard Spec
Components / BOM
  • Inlet Port
