2-way zone valve motorized
Back to previous pageThis zone valve is equipped with a ball valve and an actuator. Is perfectly suited for district heating installations or stand-alone systems. The valve is completely pre-wired if preferred and fitted with a transformer. This allows a thermostat to be connected easily. Next to district heating systems the zone valve can be used in domestic installations where a house is divided into several comfort zones. Thanks to the high-pressure resistance and closing power this solution is not only simple but also very solid and safe.
