PN16
Burkert 19038 (Type 0331) is a direct-acting, media-separated pivoted armature solenoid valve configured for 3/2-way normally closed (Circuit Function C) operation. This specific model features a brass body with a flange connection, NBR seals, a 4.0 mm orifice, and operates on 12 V DC. It is designed to handle pressures from -1 to 3 bar and medium temperatures up to 80 °C. The solenoid coils are moulded with a chemically resistant epoxy, and the coil system is separated from the medium by a diaphragm, making the Type 0331 family suitable for critical media.
Key Features
- Direct-acting, media-separated valve: Suitable for orifices up to DN 4.
- Pivoted armature technology: Maintenance-free design with long service life.
- Manual override: Service-friendly and robust manual override for start-up and testing.
- High protection: IP65 degree of protection with a correctly connected cable plug.

Installation and Operation
DANGER!
Risk of injury from high pressure and electric shock
- Before working on equipment or device, switch off the pressure and deaerate/drain lines.
- 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.
Manual Override
When the manual override is locked, the valve cannot be electrically actuated.
- Press and hold the manual override.
- Turn manual override clockwise to lock.
Electrical Connection
- Connect L1/+ and N/– to terminals 1 and 2 independently of the polarity.
- Connect the protective conductor.
- Install an approved cable plug (e.g., Type 2518 or 2509 in accordance with DIN EN 175301-803 Design A).
- Observe voltage and current type in accordance with the type label.
- Screw the cable plug in place, observing the maximum torque of 1 Nm.
