Burkert 48988 (Type 0330) is a direct-acting, media-separated pivoted armature solenoid valve. Configured with a 3/2-way normally closed circuit function (C), this specific model features a 3.0 mm orifice, a stainless steel body, and FKM seals, making it highly suitable for critical and aggressive media. The solenoid coil is moulded with a chemically resistant epoxy, and the internal coil system is completely separated from the medium by a diaphragm. It operates on 48 V DC and handles pressures from 0 to 10 bar.

Safety Instructions

DANGER

Risk of injury from high pressure in the system/device ▶ 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. ▶ Observe the applicable accident prevention and safety regulations for electrical devices.

WARNING

Risk of burns or fire from hot device surfaces due to prolonged activation time ▶ Keep the device away from highly flammable substances and media and do not touch with bare hands.
