The BURKERT 54057 (Type 0330) is a direct-acting, media-separated pivoted armature valve. It is configured as a 3/2-way variant with Circuit Function C (normally closed). 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 54057 features a brass body, EPDM seals, a 3.0 mm orifice, and operates on 24 V DC. It is equipped with a service-friendly, robust manual override for start-up and testing.

TIP

For safe operation of the solenoid valve, a dirt trap (≤ 500 µm) must be installed before the valve inlet.
