VA20 2-port valve
The 2-port valve RESOL VA20 is used for switching flow rates in solar, heating and air conditioning systems. The VA20 is a 2-port-valve with an electrothermal actuator. The actuating time of approx. 3 minutes enables a flow rate regulation without water hammers. The VA20 comes with brass connection fittings.
