Servo-assisted 2/2-way diaphragm valve

Servo-assisted diaphragm with diameter of up to DN 50
• Hard-coupled diaphragm opens without differential pressure
• Vibration-proof, block screwed coil system
• Damped design for quiet closing
• Energy-saving power reduction in all DC versions

The 0290 valve is a servo-assisted solenoid valve of the S.EV series. The valve opens without differential pressure. The opening process is supported by the fi xed coupling of the diaphragm to the plunger . In the process, the integrated ‘soft-kick’ function opens in a manner that is gentle on the material. Various diaphragm material combinations are available depending on the application. The housing offered is rounded out by a stainless steel and grey cast iron version. The solenoid coils are moulded with a chemically resistant epoxy. ‘Kick and drop’ electronics are moulded into all DC variants for reduced electrical power consumption. In combination with a plug in accordance with DIN EN 17301-803 Form A,the valves satisfy protection class IP65 – in
combination with a stainless steel housing NEMA 4X .

Type 0290 - 伺服辅助式两位两通隔膜电磁阀

0290为伺服式S.EV系列电磁阀。不需压差即可打开阀门。其打开过程是通过膜片与铁心的固定耦合完成的。内置的“soft-kick”功能以温和的方式打开阀门。根据不同的应用，可以选择各种膜片材质。阀体材质为不锈钢和灰铸铁。电磁线圈采用耐化学腐蚀的环氧树脂封装。所有 DC 式都带“kick and drop”电子线路，用以降低功耗。与 DIN EN 17301-803 A 型电缆插头配套，该阀的安全防护等级为 IP65，不锈钢阀体式 NEMA 4X。
