The GARDENA 24 V Irrigation Valve is required for operation of the GARDENA Irrigation Control Systems 4040 modular, 4030 and 6030 (Art. No. 1276-20, 1283-20, 1284-20) and the Comfort Expansion Module (Art. No. 1277-20). For connection it has a 1" female thread. If required, manual opening or closing of the valve is possible; in this way, irrigation can be opened or closed independently of an automatic irrigation control. For uninterrupted operation, a self-cleaning filter is integrated. The GARDENA 24 V Irrigation Valve operates with an operating pressure of 0.5 to 12 bar.
