Caleffi 5027 Automatic Air Vent, 1/8", MPT, 150 psi Working, 240 deg F, Brass

Automatic air vents are designed to remove trapped air that accumulates in heating and air conditioning systems automatically
• Air removal enhances performance and life of a system by reducing the effects of corrosion due to oxygen, pockets of air trapped in the heating emitters and cavitation in the circulation pumps
• These automatic air vents eliminate residual air in heating and air conditioning systems without the need for manual intervention
• This prevents undesired noise, wear of devices in the circuits and inefficient performance of heating units
• 90 psi maximum discharge pressure
• 1.75 scfm max discharge rate

Cash Acme VR-801 Vacuum relief valve is designed to protect hot water supply systems and pressure vessels against negative pressure. It is especially well suited for many domestic and commercial systems. It works by preventing internal Vacuum conditions that could result in burned out heaters and/or collapsed storage tanks. Installed on the cold water supply line, the Cash Acme VR-801 closes tightly under pressure and opens at a 1" mercury Vacuum. Atmosphere admitted to the system breaks the Vacuum, preventing collapse of the storage tank.,
