• Z1 series normally closed actuator fits on Z2 and Z3 series valve bodies with the push of a butTon
• 7/8" knockout for 1/2" conduit connector
• With 18" wire microswitch

• 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
