Main Distribution Manifold

Product Specifications

Technical details and manufacturing context for Main Distribution Manifold

Definition

A main distribution manifold serves as the central hub within distribution manifold/duct systems, receiving a single input stream (such as fluid, gas, or air) and efficiently distributing it to multiple downstream branches or zones. It ensures balanced flow distribution, pressure regulation, and system control at the primary distribution level. This component is typically used in industrial fluid handling, HVAC, and process systems where a single source must feed multiple points. The manifold is designed to handle a range of nominal diameters from DN15 to DN100 (per ISO 6708), and flow rates from 10 to 100 m³/h. Operating temperature range is -40°C to 85°C. Body materials are stainless steel grades 304 or 316L (per ASTM A276), with seal materials of PTFE or EPDM. Port configurations range from 2 to 8 outlets. Connection types are threaded (up to DN50) or flanged (above DN50), referencing ISO 228 and ISO 7005. Surface finish is Ra ≤ 0.8 μm (per ISO 4287) for hygienic applications. Weight varies from 5 to 50 kg depending on size and material. The manifold may incorporate valves, regulators, or flow control mechanisms to manage distribution ratios, pressure balancing, and directional control. It is essential to verify model-specific values and standards with the legal manufacturer or supplier before procurement, as the listed parameters are reference ranges. The manifold is a component, not a standalone system, and its performance depends on the entire distribution network. Proper selection requires consideration of inlet pressure, port size, media compatibility, and environmental conditions. Regular inspection of seals and pressure ratings is recommended to maintain integrity and prevent leaks.

Working Principle

The manifold operates by receiving a centralized input through an inlet port, then dividing the flow through multiple outlet ports connected to distribution branches. It may incorporate valves, regulators, or flow control mechanisms to manage distribution ratios, pressure balancing, and directional control to various system sections. The internal geometry ensures even distribution, while optional features allow adjustment of flow to each branch. The operating pressure and temperature must stay within the specified ranges to maintain seal integrity and structural safety. Flow rate depends on inlet pressure and port size, and the manifold's design ensures minimal pressure drop across the system.

Frequently Asked Questions

Can this manifold be used for hygienic applications?

Yes, the surface finish can be Ra ≤ 0.8 μm (per ISO 4287), which is suitable for hygienic applications. However, the seal material and body material must be compatible with the media and cleaning agents. Confirm with the supplier.

What are the available connection types?

Connection types are threaded (up to DN50) or flanged (above DN50), referencing ISO 228 and ISO 7005. The choice depends on the piping system and pressure requirements.

How many outlet ports can this manifold have?

The port configuration ranges from 2 to 8 outlets. The number of ports affects the flow distribution and pressure drop. Select based on the number of downstream branches needed.
