SFV-AP Breather caps

SFV-AP Breather caps

The SFV-AP valve breather cap is specifically designed for applications where internal air pressure must not exceed a certain level, such as in gear reducers, variators, or compressors. The built-in safety valve releases excess air when necessary, ensuring optimal pressure conditions.

Key Features:

  • Material: Polyamide-based (PA) technopolymer

  • Cover: Orange (RAL 2004), semi-matte finish, with valve symbol

  • Threaded fitting with splash guard: Black, semi-matte finish

  • Sealing ring: Flat washer made of NBR synthetic rubber

  • Overpressure valve: Technopolymer housing with NBR O-ring seal

  • Stainless steel spring: Set at 0.35 bar or 0.7 bar

  • Maximum continuous operating temperature: 100°C

Function and Benefits:

  • The valve remains closed under normal pressure conditions, preventing dust ingress and oil loss.

  • Its special internal design prevents fluid leakage even in cases of strong splashing.

  • Available in two versions:

    • SFV-AP-350MB: Opens when pressure exceeds 0.35 bar

    • SFV-AP-700MB: Opens when pressure exceeds 0.7 bar

Custom Versions Available on Request:

  • Black-colored cover

  • Version with a flat dipstick

 

The SFV-AP breather cap is a reliable and efficient solution for systems where pressure regulation and protection against contamination are essential.
