Valworx Launches DA85 Pneumatic Actuator for Pipeline Systems

Imagine a world where manually operating valves becomes obsolete — where a simple button press can automatically control entire pipeline systems. This isn't science fiction but the reality enabled by pneumatic actuators. Among these solutions, the Valworx DA85 double-acting pneumatic actuator stands out for its ability to make valve operations smarter and more efficient.

Pneumatic actuators are devices that use compressed air to operate valves. The double-acting variety, as the name suggests, utilizes air pressure for both opening and closing movements. With two separate air ports controlling piston movement in opposite directions, these actuators enable precise valve control. This design makes them particularly valuable in applications requiring rapid, reliable valve operation.

The Valworx model 530085 DA85 pneumatic actuator is a high-torque solution designed specifically for quarter-turn valves. It effectively operates ball valves, butterfly valves, plug valves, and dampers. The actuator features a compact rack-and-pinion design that delivers substantial power while remaining easy to install and maintain.

• Durability: Pre-lubricated and tested for at least 1 million cycles, the DA85 withstands demanding industrial environments, reducing replacement and maintenance costs.
• Corrosion Resistance: The aluminum body undergoes 50-micron hard anodizing, while polyester powder-coated aluminum end caps endure 500-hour salt spray testing, ensuring performance in humid or corrosive conditions.
• Easy Installation: Featuring ISO5211 standard mounting and dual square output drive, the DA85 quickly adapts to various valves, minimizing setup time.
• Visual Indicators: Clear position indicators provide immediate valve status feedback, preventing operational errors.
• Control Flexibility: Compatible with both lubricated and dry compressed air, the DA85 includes Namur interfaces for direct solenoid valve mounting, enabling electrical control integration.

The DA85 serves numerous industries requiring automated valve control:

• Oil & Gas: Manages crude oil, natural gas, and chemical distribution
• Water Treatment: Controls water, wastewater, and sludge flow
• Food & Beverage: Regulates ingredient transfer and mixing processes
• Pharmaceutical: Handles raw materials and solvent distribution
• Power Generation: Manages cooling water, steam, and fuel systems
• HVAC: Regulates thermal fluid circulation

When choosing pneumatic actuators, consider these factors:

1. Valve Specifications: Match actuator torque to valve size and type requirements
2. Operating Environment: Account for temperature, humidity, and corrosive elements
3. Control Method: Select between manual, electrical, or pneumatic operation
4. Safety Compliance: Verify certifications for hazardous environments

The DA85 requires minimal setup:

• Mount to ISO5211-compliant valves using proper fasteners
• Ensure clean, flat mating surfaces
• Secure air connections without leaks

Maintenance involves periodic inspections of:

• Physical integrity
• Air line connections
• Moving component lubrication

Various add-ons enhance functionality:

• Solenoid valves for PLC integration
• Limit switches for position feedback
• Positioners for flow regulation
• Manual overrides for emergency operation

The Valworx DA85 represents a durable, adaptable solution for industrial valve automation. Its combination of robust construction, straightforward installation, and operational flexibility makes it suitable for diverse applications where reliable performance is essential.
