Couplings for gases and liquids
Couplings with cut-off valve are used for fast connection of cooling systems in semi-automatic welding machines and also in a great number of pneumatic devices.
SPA series couplings are equipped with cut-off valve which prevents uncontrolled flow of medium. It allows immediate disconnection of hoses and rearming of welding station without necessary medium flow closing.
