- It features a primary check valve utilizing a rubber disc seating against a mating rubber part to ensure tight closing
- A secondary check valve utilizes a rubber disc-to-metal seating
- In the event of fouling of the downstream check valve, leakage would be vented to atmosphere through the vent port thereby safeguarding the potable water system
- True line-sized construction allows the check modules to open further allowing dirt and debris to pass more freely reducing check fouling
- Maximum flow at low pressure drop
- Furnished with union connections to facilitate removal and replacement for maintenance
- Compact for economy combined with performance
- Design simplicity for easy maintenance
- Can be installed vertically or horizontally

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
