A solid block or header that distributes fluid or gas from a single source to multiple outlets within a delivery manifold system.

Product Specifications

Technical details and manufacturing context for Manifold Block/Header

Definition
The manifold block/header is a critical component of delivery manifold and valve systems, serving as the central distribution point where a single input flow is divided into multiple output channels. It provides mounting surfaces for valves, sensors, and fittings while maintaining structural integrity under pressure. In industrial applications, it ensures controlled distribution of liquids or gases to various process points with minimal pressure drop and leakage.
Working Principle
Fluid or gas enters through a single inlet port and is distributed through internal passages to multiple outlet ports. The block's internal channels are precision-machined to maintain flow characteristics, while sealing surfaces prevent leaks between connections. Valves mounted on the block regulate flow to individual outlets.
Common Materials
Stainless Steel, Aluminum, Carbon Steel
Technical Parameters
  • Overall dimensions including length, width, height, and port-to-port spacing (mm) Per Request
Components / BOM
  • Mounting Holes
    Secure the block to equipment or framework
