BURKERT 20073231 Type 8640 modular valve island 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. Electrical connectivity is achieved by either fieldbus interfaces, common connection (parallel connection technique), or multipin interfaces. The valves allow different applications to be covered. Bodies and connection modules are made of high-quality plastic (polyamide) and are easy to assemble by means of the built-in snap connectors.

Key Features

• Compact design
• Modular configuration
• Higher flexibility in control cabinet due to AirLINE Quick
• Simple exchange of valves (with option “P-shut-off” – also possible during operation)

AirLINE Quick

AirLINE Quick considerably reduces the use of components in the control cabinet. With the AirLINE Quick Adapter, the valve terminal is adapted directly to the control cabinet floor or control cabinet wall.

Advantages:

• Reduced space requirement in the control cabinet
• This makes it possible to use more compact control cabinets
• Reduced installation effort due to hose connections directly at the bottom of the control cabinet

Note

Type 0460 valves cannot be installed with AirLINE Quick because of their size.

Dimensions (11 mm width per station)

Installation

DANGER!

Risk of injury due to high pressure and escaping medium.

• 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.
• Observe any applicable accident prevention and safety regulations for electrical devices.

WARNING!

Risk of injury from quickly accelerating device parts and unconnected compressed air hoses flapping around.

• Before applying pressure to the valve, check all hose connections and fittings for tight, secure fit.

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.

Tightening Torques for Port Connections

Port size	Marking/function	Recommended tightening torque [Nm]	Maximum tightening torque [Nm]
G1/4, NPT1/4	P, R/S connection	4...7	20
G1/8, NPT1/8	P, R/S connection A/B valve outlets	3...6	7
