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
-
