Overview
The Coilhose SV804 excess flow check valve is a safety accessory designed for compressed air lines serving pneumatic tools and equipment. This valve is designed to automatically shut off air flow upon a sudden break in the air line, thereby protecting personnel and property from “whipping” air hoses. The SV804 maintains full unrestricted airflow during normal operation while providing critical safety protection in emergency conditions.
