Burkert Type 5420 (SKU 463891) is a pilot-controlled 4/2-way seat valve with servo-diaphragms. The valve is designed for pneumatic applications and features a compact design with a push-over solenoid coil. It can be mounted on two-channel manifolds with a common pressure supply, offering flexible installation options for industrial automation.

INFO

A minimum differential pressure of 2.5 bar is needed for switch-over. The exhaust air can be regulated to suit specific application requirements.

Key Features

• Compact Design: Space-saving construction suitable for manifold mounting.
• Push-over Solenoid Coil: Simplifies assembly and maintenance.
• Regulable Exhaust Air: Allows for precise control of pneumatic actuators.
• Seat Valve Variant: Ensures reliable sealing and long service life.

Installation and Wiring

WARNING

Before installing the valve, ensure that piping is free of foreign matter (metal shavings, pipe sealing materials, welding scale, etc.). Installation is as required, but preferably with the coil uppermost to prevent foreign matter from remaining in the core tube.

Electrical Connection

Ensure the supply voltage corresponds with that on the label. The voltage tolerance is ± 10 %.

Orientation of the electrical connection is not important.
