Burkert Type 0330 (SKU 366334) is a direct-acting, media-separated pivoted armature solenoid valve. This specific explosion-proof variant features a stainless steel body, FKM (fluor rubber) seals, and an NPT 1/4 internal thread connection. It operates at 24 V with a 3-meter wire cable electrical connection and is designed for universal use (Circuit Function T). The coil system is separated from the medium by a diaphragm, making it suitable for critical media such as aggressive acids and alkalis.

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.
• Observe the applicable accident prevention and safety regulations for electrical devices.

Risk of burns or fire

• The solenoid valve can become very hot during continuous operation. Keep the device away from highly flammable substances and media and do not touch with bare hands.
