What type of pneumatic valve is this?

This is an electrically actuated, pilot-operated 5/2-way bistable directional valve. Its five ports and two switching positions allow it to direct compressed air between two working connections.

What applications is this valve suitable for?

The valve is suitable for controlling double-acting pneumatic actuators, such as cylinders used in material handling, clamping and automated production equipment. Suitability depends on the application's airflow, pressure and mounting requirements.

What does bistable operation mean?

Bistable operation means the valve has two stable switching positions rather than a spring-return default position. A switching signal selects the required position, which is retained until the opposite switching command is applied, provided the necessary pneumatic conditions are maintained.

What is the standard nominal flow rate?

The standard nominal flow rate is 1,200 litres per minute. Actual airflow depends on the operating pressure, pressure differential and restrictions in the connected pneumatic circuit.

What operating pressure range does the valve allow?

The specified operating pressure range is −0.9 to 16 bar. The external pilot air supply must separately meet the specified pilot pressure requirements.

Does this valve require an external pilot air supply?

Yes. The valve uses an external pilot air supply, with a specified pilot pressure range of 2 to 10 bar. This supply operates the pilot stage that switches the main valve.

How is the valve mounted?

The valve mounts on a sub-base and uses an ISO 5599-1 size 1 connection interface. Its mounting arrangement includes through-holes, and it can be installed in any orientation.

Are solenoid coils and electrical sockets included?

Festo 152563 is specified without solenoid coils or electrical sockets. These components must be selected and ordered separately, with the coil voltage matched to the machine's electrical supply.

Does the valve have a manual override?

Yes. Manual overrides are provided. The datasheet identifies a push-operated override and a detenting option used with accessories, allowing local actuation during setup and functional checks.

What temperature ranges are specified?

The specified ambient temperature range is −5°C to +40°C. The compressed-air medium temperature range is −10°C to +60°C.

What compressed-air quality is required?

The operating and pilot medium is compressed air meeting ISO 8573-1:2010 class [7:4:4]. Lubricated operation is permitted, but once lubrication is introduced, it must be continued during subsequent operation.

What materials are used in the valve?

The valve has a die-cast aluminium housing and seals made from FPM and NBR. It uses a piston-slide design with soft sealing.

Can the exhaust airflow be throttled?

Yes. The valve's exhaust-air function is specified as throttleable. The complete pneumatic circuit should be assessed when selecting exhaust-flow restrictions for actuator speed control.
