Valworx Launches Highperformance Stainless Steel Actuator for Industrial Automation

In harsh industrial environments with stringent hygiene requirements, equipment durability and reliability become critical factors for operational success. Valworx has recently launched its new generation DA105 stainless steel double-acting pneumatic actuator, designed to deliver exceptional corrosion resistance, robust construction, and flexible installation options for automation systems in petroleum, chemical, pharmaceutical, and food & beverage industries.

Many industrial applications expose equipment to corrosive media, humid conditions, and frequent washdown requirements. Traditional actuator materials often suffer from limited lifespan and potential safety hazards caused by corrosion, negatively impacting production efficiency and product quality.

The Valworx DA105 actuator addresses these challenges with its all-stainless-steel construction, featuring 316 stainless steel body, end caps, and piston for superior corrosion resistance. The precision electropolished exterior surface enhances both aesthetics and durability during cleaning and sanitization processes, making it ideal for pharmaceutical and food processing applications where cleanliness standards are exceptionally high.

The DA105 double-acting pneumatic actuator employs a classic rack-and-pinion mechanism to ensure precise 90° (quarter-turn) rotary motion, making it perfect for operating butterfly valves, ball valves, and other quarter-turn valves. Its dual-action design—using controlled air input and exhaust to open and close the actuator—proves particularly valuable in applications requiring exact valve positioning.

Pre-lubricated and rigorously tested for at least 1 million cycles, the actuator delivers long-term operational stability. The robust construction ensures reliable performance even in demanding conditions, while the corrosion-resistant materials minimize maintenance requirements.

Understanding field installation challenges, Valworx designed the DA105 with versatility in mind. Its ISO5211-compliant valve mounting interface allows quick, reliable connection with most standard valves. The double square bore output drive further simplifies valve stem matching.

The actuator features a NAMUR mounting interface that enables direct installation of optional solenoid valves on the actuator side, eliminating additional piping connections. This space-saving design reduces potential leak points while significantly cutting installation time and improving overall system reliability.

To meet increasingly complex automation needs, the DA105 offers multiple accessory options. Users can select stainless steel solenoid valves in different voltages (120V 50/60Hz or 24 VDC) for electrical control. The ISO DIN plug with 16-foot cable simplifies electrical connections.

Optional stainless steel limit switches (IP67/NEMA 4X rated) provide real-time valve position feedback to control systems, while electro-pneumatic positioners enable precise valve positioning for continuous control applications. These smart features expand the actuator's application potential in sophisticated process control scenarios.

The DA105 system can be enhanced with several compatible accessories:

• Stainless Steel Solenoid Valves: Available in 120V 50/60Hz and 24 VDC configurations with high protection ratings
• ISO DIN Plug with 16-foot Cable: Simplifies electrical connections with sufficient cable length
• Stainless Steel Limit Switches: IP67/NEMA 4X rated for accurate valve position feedback
• Electro-Pneumatic Positioners: Enable 4-20mA proportional control for precision process applications

With its durable construction, corrosion resistance, flexible installation, and smart control capabilities, the Valworx DA105 stainless steel actuator represents a reliable solution for industrial automation systems requiring efficiency, safety, and process optimization.
