The Taconova NovaZone DN 15 three-way zone valve is equipped with an electric motor and a return spring for circuit control in cooling, heating, and air conditioning systems. It adjusts the supply of the desired medium in individual zones or systems using a manual lever. The spindle is sealed with a series of O-rings. The flow medium can be water or glycol mixtures.

Features

• Power supply 230 VAC
• Flow rate 4 m3/h
• Pressure 10 bar
• Connection size DN 15

Installation

• Any position (must follow the direction of media flow)

Function

• The change in valve body position is initiated by a single-pole contact (e.g., switch or thermostat). Without power, the spring returns the valve to its original position, so the valve cannot be stopped in an intermediate position. 

Advantages

• The switching interval is very short, a maximum of 20 seconds
• The valve can be manually operated using a side lever 
• Minimal maintenance requirements 
• Visible valve position 
• Wide temperature range of the flow medium from -20 °C to 160 °C 
• Body made of brass

Technical Data of the Electric Motor

• Energy consumption: 6 W
• Cable length: 1 m
• Operating voltage: 230 V (50Hz)
• Opening interval: approx. 12 seconds
• Closing interval: approx. 5 seconds
