Product Specifications

Technical details and manufacturing context for Vacuum Distribution Manifold

Definition
The vacuum distribution manifold is a critical component within nozzle holder/turret assemblies, designed to efficiently route and control vacuum suction from a single pump or source to multiple individual nozzles. It ensures consistent vacuum pressure is delivered to each nozzle for reliable material handling, part positioning, or pick-and-place operations in automated machinery.
Working Principle
The manifold receives vacuum pressure from a central source through a primary inlet. Internal channels and valves within the manifold body distribute this vacuum to multiple outlet ports, each connected to a separate nozzle. Pressure regulators or flow control valves may be integrated to balance suction force across all nozzles, ensuring uniform performance.
