BURKERT 20059157 (Type 0330) is a direct-acting, media-separated pivoted armature valve. As a 3/2-way variant (Circuit Function F), it operates as a distribution valve where normally inlet port 1 (P/IN) is connected with outlet port 2 (B/NO), and outlet port 4 (A/NC) is 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 20059157 model features a stainless steel body, FKM seals, and operates on 24V DC.

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 injury due to improper installation

• Installation may only be performed by trained technicians and with the appropriate tools.
• Secure the system against unintentional activation.
• Ensure a controlled restart after installation.
