Applications:
Foster SV and SVPC Series Safety Vent couplings are designed for maximum user and equipment safety. Foster SV and SVPC Series couplings allow for safe and easy connection/disconnection under zero line pressure to minimize the possibility of inadvertent disconnection and potential hose whip. The fully encapsulated non-marring models significantly reduce the risk of surface nicks and scratches. Ideal for use in paint booth applications or for air lines used around finished surfaces, such as fiberglass, painted metal or glass surfaces.
Features:
Zero Pressure Connect and Disconnect Design Made in the USA Rubber or polyurethane hose connections available Extra thick heat-treated steel walls extend service life Zero pressure connect/disconnect design vents down stream pressure for safe, easy connect/disconnect. It also minimizes possible inadvertent disconnection and potentially dangerous hose whip “O-ring” plug seal for leak-free performance No replacement parts used (valve, spring, or washer) that could block flow of air. Silicone-free assembly. Meets ISO 4414, 9.6 Quick-Action Couplings requirements: Quick-Action (quick release) couplings shall be selected so that when they are coupled or uncoupled a) the coupling shall not be forced apart in a hazardous manner b) compressed air particles shall not be expelled in a hazardous manner c) a controlled pressure-release system shall be provided where a hazard may exist.
