221G21 Solenoid valve without coil

The versatile G-Series comprises both direct and indirect operating solenoid valves, specifically designed for the demanding conditions of industrial and process markets. A key quality feature of this series is the reinforced diaphragm construction combined with a heavy-duty stainless steel actuator, designed for millions of switching cycles, thus guaranteeing exceptional durability. The Magnalift-operated variants are particularly noteworthy, as they switch reliably without any minimum pressure, offering maximum application flexibility. This robust design significantly optimizes total cost of ownership in demanding applications such as compressor technology, air treatment, and the control of oil burners, as well as water and steam systems. Thanks to a wide selection of electrical components with international certifications according to VDE, UL, and ATEX, the G-Series is also the ideal solution for precise fluid and gas control, as well as actuator control, in both safe and highly sensitive, potentially explosive environments.
