BURKERT 20034027 (Type 0330) is a direct-acting, media-separated pivoted armature valve. It is configured as a 2/2-way normally closed (Circuit Function A) solenoid valve. The solenoid coils are moulded with a chemically resistant epoxy. Since the coil system is separated from the medium by a diaphragm, the valve is especially suitable for critical media such as aggressive acids and alkalis. The 20034027 variant features a brass body, FKM seals, a G 1/4 port connection, and operates on 110 V DC.

Performance Specifications

For the standard variant with a brass body and FKM seal (DN 3):

• Kv value (water): 0.14 m³/h (DC frequency)
• Pressure range: 0 to 10 bar
• Medium temperature: 0 °C to +90 °C
• Ambient temperature: Max. +55 °C
• Viscosity: Max. 37 mm²/s

Note on Kv Value

The K value at DC frequency is reduced by up to 10% to guarantee the function. Measurement at +20 °C, 6 bar at the valve outlet.

Dimensions

The dimensions for the metal body variant with G 1/4 thread are as follows:

• D1: G 1/4
• L1: 9 mm

Installation Note

The device can be attached via the existing holes on the bottom side. The hole pattern is 38x24. For metal bodies, use M4 screws. The minimum thread length at the middle connection is 7.5 mm.

Installation and Safety

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.

• Dirt trap: For safe operation of the solenoid valve, a dirt trap (≤ 500 µm) must be installed before the valve inlet.
• Manual override: When manual override is locked, the valve cannot be electrically actuated.
