Use with VOLCANO fan heaters:
The two-way valve with an NVMZ servo actuator is controlled by a thermostat or a programmed controller. The control elements supply power to the actuator to open the valve. Fast response time allows you to smoothly control the air temperature without differences. The NVMZ also serves to maintain a stable and accurate temperature. And prevents overspending of energy.
Use with WING Thermal Curtains:
A two-way valve with an NVMZ servo actuator is used, similar to the Volcano fan heater, controlled by the DX panel. The control elements supply power to the actuator to open the valve. Caution if there is no power, the valve closes. ensure that the valve opens mechanically to prevent freezing of the heat exchanger in the WING curtain.
