Burkert 353678 (Type 0330) is a direct-acting, media-separated pivoted armature solenoid valve. It is an explosion-proof 3/2-way variant with circuit function T (universal use). The solenoid coil is moulded with a chemically resistant epoxy, and the coil system is separated from the medium by a diaphragm, making it suitable for critical media such as aggressive acids and alkalis. This specific model features a stainless steel body, FKM seal, NPT 1/4 port connection, 3.0 mm orifice, and operates at 230 V.

Safety Instructions

• Risk of injury from high pressure: Before working on equipment or device, switch off the pressure and deaerate/drain lines.
• Risk of injury from electric shock: Before working on the system or device, switch off the power supply and secure against reactivation.
• Explosion hazard: The solenoid coil forms a closed system after installation. When used in an explosion-risk area, there is a risk of explosion if the system is opened in the operating state.
