One-Way Safety Valve, IP68 for Overpressure Relief

Our One-Way Safety Valve provides critical IP68 protection for sealed enclosures. This aluminum valve remains perfectly sealed until a preset pressure is reached, then automatically vents and reseats.

Key Features

  • One-Way Pressure Relief: Functions as a normally-closed one-way valve that automatically opens to vent excess pressure when a preset value (e.g., 5-50 KPA) is reached.
  • Automatic Reseating: The valve core automatically closes and reseals after the pressure has been released, maintaining the system’s protection and integrity.
  • Hardened Aluminum Construction: CNC machined from 6061 aluminum alloy with an ultra-hard, anti-corrosion surface treatment (HV600+), offering a lightweight yet durable solution.
  • IP68 Waterproof & Dustproof: When closed, the valve provides the highest level of protection against dust and long-term water immersion, ensuring no external contaminants enter the enclosure.
  • Designed for High-Reliability Equipment: Ideal for protecting sensitive systems in power plants, metallurgy, marine applications, and various outdoor electrical equipment.
  • High Safety Standards: Materials are V0 flame retardant and RoHS 2.0 compliant, ensuring safety and environmental standards are met.
