Component Specifications

Definition
A drain port is an engineered component integrated into filter housing assemblies, featuring a threaded or flanged connection point that allows for the systematic evacuation of residual fluids, particulate matter, or separated phases (like water in fuel filters). It typically includes a valve or plug mechanism to enable opening during draining procedures and secure sealing during normal filtration operation, preventing leaks and maintaining system integrity. Common in pressure vessels and filter housings across industries, it facilitates maintenance, reduces downtime, and enhances filtration efficiency by removing unwanted accumulations.
Working Principle
The drain port operates on a simple on-off principle: when opened (manually or automatically), it creates a low-pressure pathway for fluids to exit the filter housing due to gravity or system pressure, allowing drainage of contaminants; when closed, it forms a pressure-tight seal to maintain the housing's internal environment and prevent fluid loss or contamination ingress.
Materials
Typically made from corrosion-resistant materials such as stainless steel (e.g., SS304, SS316), brass, or engineered plastics (e.g., PVC, polypropylene), chosen based on fluid compatibility, pressure ratings, and environmental conditions.
Technical Parameters
  • Size Commonly 1/4" to 1" NPT or metric equivalents
  • Valve Type Manual ball valve, needle valve, or automatic drain valve
  • Connection Type Threaded (e.g., NPT, BSP), flanged, or quick-disconnect
  • Pressure Rating Up to 150 psi (10 bar) standard, higher for specialized applications
  • Temperature Range -20°C to 120°C, depending on material
Standards
ISO 1179, DIN 3852, ASME B1.20.1
