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
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
