Releases Air: Safely exhausts large pockets of trapped air when filling a pipeline (pump startup) to prevent blockages.
Relieves Vacuum: Sucks air back in when the system shuts down, preventing the pipes from collapsing in on themselves.
Continuous Venting: Continuously bleeds smaller amounts of entrapped air while the system is running under high pressure.
Size: 2" NPT (National Pipe Thread) connection.
Materials: Made of corrosion-resistant, glass-filled nylon body/base with a polypropylene float.
Capacity: Handles working pressures up to 125 psi.
Design: Aerodynamic internal float design resists blowing closed prematurely.
Special Features: Includes an internal protection screen and a discharge elbow.
