Manifold (Distribution Header) for Spray Systems

Product Specifications

Technical details and manufacturing context for Manifold (Distribution Header)

Definition

The manifold (distribution header) is a central component in industrial spray systems, serving as the distribution point that receives fluid from a single source and directs it to multiple spray nozzles or outlets. Its primary function is to ensure consistent pressure and flow across all connected nozzles, enabling uniform application in processes such as coating, cooling, or cleaning. Constructed from stainless steel (SS304 or SS316), the manifold is designed to withstand demanding industrial environments. Key specifications include a number of outlets ranging from 4 to 12 ports, with custom counts available to match specific coverage requirements. Inlet connection sizes range from 1 to 4 inches, and outlet connection sizes from 1/4 to 1 inch, both conforming to ISO 228-1 for thread compatibility. The operating pressure range is 1.0 to 1.6 MPa, with a maximum pressure of 2.5 MPa; exceeding the maximum could cause permanent deformation. Operating temperature ranges from -40°C to 85°C, limited by seal material. Flow capacity is 10 to 100 L/min, depending on pressure drop and outlet size. Surface finish is Ra 0.8 to 1.6 µm, with smoother finishes available for hygienic applications. Weight varies from 2 to 15 kg. Leakage rate is 0.01 mL/min at rated pressure with water. Material grades conform to ASTM A276. These values are reference ranges; verify model-specific data with the manufacturer or supplier before selection.

Working Principle

Fluid enters the manifold through a single inlet port and is distributed through internal channels to multiple outlet ports. The internal design minimizes pressure drop and maintains flow consistency across all outlets, enabling simultaneous operation of multiple spray nozzles from a single supply line. The manifold acts as a hydraulic junction, balancing flow and pressure to each nozzle, which is critical for uniform spray coverage. Proper sizing of the manifold, including inlet and outlet connections, ensures that the system operates within the specified pressure and flow limits.
