BURKERT Type 8640 modular valve island (SKU 20017606) is designed to solve diverse and complex control problems due to its systematic modular construction and combination of pneumatic and electrical interfaces. By putting together a row of pneumatic modules with different numbers of valves, 2 to 24 valve functionalities may be realized on one valve unit.

The 19 mm width per station variant utilizes the Type 5470 solenoid valve, which consists of a pneumatic valve body fitted with a Type 6106 rocker pilot valve. The minimal tilting movement of the rocker is non-wearing, and basic lubrication is unnecessary.

Key Features

• Compact design with modular configuration
• 19 mm width per station
• Simple exchange of valves
• DIN-rail installation

Structure and Design

The Type 5470 valves can be mounted on the modular, pneumatic type MP05 base rails to form valve blocks. Any installation position is possible, preferably with the solenoid actuator on top.

Components:

1. Pilot valve Type 6106
2. Exhaust port 3
3. Pressure port 1
4. Working port 4
5. Working port 2
6. Manual override
7. Cable plug Type 2506

Manual Override

To operate the valve manually, press the manual override and turn it 90° clockwise (until it stops). The manual override is locked and does not reset automatically. Only operate the manual override when the power is off.

Installation

Safety Instructions

• Risk of injury due to high pressure: Switch off the pressure before working on the device or system. Vent or drain the pipes.
• Risk of injury due to electric shock: Switch off voltage before working on the device or system. Secure against reactivation.

Valve Block Installation

Standard rail installation:

1. Hook the valve block with the upper groove into the standard rail (35 x 15 or 35 x 7.5 EN 50022).
2. Snap the lower clamping pieces into the standard rail.
3. Tighten the screws on the clamping pieces.

Wall installation: Fasten the valve block directly to the wall with M4 screws.
