18" wire lead connection

A snap on actuator allows for fast installation and easy replacement with a convenient in-line push button.

A gear ratio of 21:1 in the actuator increases torque for high close-off pressure and increases closing time to reduce water hammer.

Compact design provides quick and easy installation, the Z-one valve fits perfectly inside baseboards and fan coils. Available with choice of NPT, sweat and press fittings for ease of installation and maintenance.

Hermetically sealed end switch in 24V actuators requires no minimum current load allowing multiple end switches connected in parallel to zoning panel.

Suitable for all types of systems - made with materials compatible with chilled or hot water up to 240°F, 15 psi steam, and open or closed systems.

Low power consumption allows up to five valves per 40 VA transformer.

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
