In the field of industrial automation, cylinders serve as core actuators, with their performance directly determining equipment efficiency and precision. Festo’s DPZJ-32-80-P-A-S2 double-piston cylinder (order code 159973) stands out as an ideal choice for automation equipment across industries such as packaging, printing, and food processing, thanks to its unique design and exceptional performance. 

Core Parameters: Foundation of Precision Driving

Basic Specifications

• Piston Diameter: 32mm, ensuring a theoretical forward stroke force of 724N and a return stroke force of 482N under 6bar working pressure, meeting medium-to-high load demands.
• Stroke Length: 80mm standard stroke, adjustable within 10mm via adjustment bolts to suit varying workstation requirements.
• Buffer Design: Integrated elastic buffer rings/pads at both ends effectively absorb terminal impact energy (0.5J), reducing mechanical vibration and noise.

Interfaces and Compatibility

• Pneumatic Connection: G1/8 threaded port compatible with mainstream pneumatic systems.
• Position Detection: Built-in magnetic ring supports precise position feedback via proximity switches, compatible with Festo and third-party sensors.
• Working Medium: Compatible with dry or lubricated compressed air (conforming to ISO 8573-1:2010 [7:4:4]), adaptable to diverse operating conditions.

Environmental Adaptability

• Temperature Range: -20°C to 80°C, covering environments from cold storage to high-temperature manufacturing.
• Corrosion Resistance: CRC Class 2, capable of handling moderately corrosive gases or dusty environments.
• Explosion-Proof Certification: Complies with ATEX II 2GD standards, suitable for potentially explosive atmospheres (e.g., chemical and pharmaceutical industries).

Technical Features: Value of Innovative Design

Double-Piston Structure for Doubled Thrust
The parallel double-piston design delivers twice the thrust of a single-piston cylinder at the same height, making it ideal for high-load, space-constrained scenarios such as sealing mechanisms in food packaging machines and paper handling systems in printing equipment.

Optimized Dynamic Performance

• Hydraulic Buffer Integration: Optional hydraulic buffers (e.g., SPZ series) enable smooth deceleration at stroke ends, avoiding hard collisions and extending equipment lifespan.
• High-Speed Response: Maximum motion speed of 1m/s, paired with large-diameter air intake design, allows rapid completion of high-frequency tasks like sorting and positioning.

Modularity and Maintainability

• Adapter Plate Design: Supports combination with other Festo drive units (e.g., swing grippers, guided cylinders) to build complex motion systems.
• Groove Cover Protection: Sensor installation slots feature protective covers to prevent debris ingress and simplify cable routing.

Materials and Craftsmanship

• Piston Rod: High-alloy stainless steel with hard chrome plating, corrosion-resistant and wear-resistant.
• Sealing System: NBR (nitrile rubber) seals ensure stable performance across -20°C to 80°C.
• Housing: Forged aluminum alloy for lightweight yet robust construction.

Typical Applications: Versatility Across Industries

Food and Packaging Industry

• Case: Drives vacuum suction cups to pick and stack bagged foods in automated packaging lines. Its double-piston design ensures stability during high-speed motion, while elastic buffers reduce packaging damage.
• Advantage: Complies with food-grade lubrication requirements and simplifies cleaning.

Automotive and Electronics Industries

• Case: Used in precision positioning stations on engine assembly lines, providing real-time piston position feedback via proximity switches to align cylinder heads and blocks with robots.
• Advantage: ATEX certification enables use in explosion-risk environments like painting workshops.

Biotechnology and Pharmaceuticals

• Case: Drives pistons for quantitative liquid filling in aseptic filling equipment. Its corrosion-resistant materials and low-temperature adaptability ensure safety when in contact with pharmaceuticals.
• Advantage: Meets GMP (Good Manufacturing Practice) standards and is easy to sterilize.

General Automation Equipment

• Case: Drives knife holders for rapid lifting in woodworking machinery’s cutting units. Its modular design allows integration with guide rods to enhance motion precision.
• Advantage: Cost-effective and easy to integrate, shortening equipment development cycles.
