Precision Valve Hardware Stainless Steel Connection Prototype Machining Food Grade
Precision-machined stainless steel connection column valve body components, CNC food-grade customization for water purification equipment.
Water Purifier / Water Dispenser (Inlet Valve, Check Valve)
Application Scope
Primarily used in water purification equipment including:
  • RO reverse osmosis purifiers
  • Ultrafiltration purifiers
  • Direct drinking machines
  • Coffee machines
  • Water dispensers
The inlet valve controls inlet water flow and provides stable water supply for purification equipment. The check valve prevents backflow of purified water, avoids filter element contamination, maintains internal pressure, and ensures normal operation of the purification process.
Core Features
  • Food-grade materials, odorless and free of heavy metal precipitation, ensuring safe purified water meeting national drinking water standards
  • Low operating pressure (0.1-0.4 MPa), matching water purification equipment requirements
  • Excellent sealing performance, no leakage, preventing mixing of unpurified water
  • Compact size suitable for internal installation space of water purification devices
Processing Notes
  • Valve body inner wall must be highly clean - free of oil, iron chips, dust with surface roughness Ra ≤ 0.8 μm
  • Materials free of heavy metal precipitation using food-grade 304 stainless steel, PP plastic, or lead-free brass
  • Heavy metal testing compliant with GB 4806.1-2016 for food contact materials
  • Food-grade certified seals using silicone or EPDM rubber - odorless, non-toxic, anti-aging, non-shedding
  • Check valve spool flexibility with reliable anti-backflow performance and low flow resistance
  • Comprehensive water quality testing and sealing tests post-processing
Selection Guide
  • Prioritize food-grade 304 stainless steel, PP plastic, or lead-free brass materials
  • Require water contact safety certification (Health Permit for Water-contact Products)
  • Choose low-noise, non-microleakage products with reliable backflow prevention
  • Match flow rate to water purification equipment requirements
  • Verify smooth valve spool movement and reliable interface sealing
