Graco 115440 Air Solenoid Valve 120VDC

Graco 115440: 120Vdc Air Solenoid Bank Valve for Enhanced Fluid Control Systems

Graco part number 115440 represents a high-performance air actuated bank valve engineered for precision control in fluid dispensing systems. This solenoid actuated device integrates seamlessly with pneumatic circuits to modulate airflow and drive multiple dispensing heads. Manufactured for heavy duty operation, it ensures consistent actuation cycles under high backpressure scenarios. Ideal for airless sprayer configurations, it supports rapid response times and long lifecycle performance in demanding industrial environments.

• High voltage stability at 120Vdc rating.
• Modular port banking with NPT port threads.
• Robust stainless steel and elastomer sealing.

Constructed from corrosion resistant stainless steel and premium elastomer composites, the 115440 valve offers exceptional durability in high-tach and abrasive environments. Ideal for professional coatings applications, the coil assembly maintains thermal stability at standard 120Vdc operating voltage and exhibits minimal coil heating during extended duty cycles. Attention to internal flow path geometry reduces turbulence and pressure drop, enhancing overall pump efficiency in high throughput systems. Compliance with industrial sealing standards further extends service intervals.

Leveraging advanced pilot actuation mechanisms, this valve excels in automated paint lines, adhesive metering modules, and corrosion resistance testing rigs. Precision flow control facilitates accurate dose regulation in multi-component mixing stations and spray header banks, while compatibility with high viscosity fluids under pressure ensures consistent output. Designed for integration with servo-driven air handling units, it can be paired with upstream high-pressure filtration systems to guard against particulate ingress, extending seal longevity and operational reliability.

Each solenoid coil winding is wound on a high permeability core to maximize magnetic flux and minimize actuation time under standard line voltage. Temperature ratings range from -20°C to 80°C, supporting ambient extremes, and cycle life exceeds five million actuations in laboratory endurance tests. The coil enclosure features epoxy encapsulation to protect against moisture and vibration, meeting IP65 ingress protection requirements. Inlet and outlet ports are configured in a bank style array, enabling direct manifold mounting and simplified piping layouts. Threaded NPT connections facilitate secure fittings without additional adaptors or sealants.

Performance specifications include a nominal Cv of 0.15 per port, supporting flow rates up to 8 liters per minute of compressed air at 6 bar. Response time is rated at under 20 milliseconds from coil energization to full port shift, ensuring rapid cycling for high frequency applications. Coil power consumption is optimized to 3.2 watts, reducing thermal load on adjacent components. This contributes to consistent output in multi-valve assemblies.

For installation, ensure alignment of manifold mounting holes to avoid stress on port connections. A recommended filtration stage upstream of the valve can markedly reduce particulate wear, preserving seal integrity and extending maintenance intervals. Periodic coil insulation tests and diaphragm inspections are advised to detect early material fatigue. Integration with electronic proportional pressure controls enables variable actuation, improving accuracy in dosing and blending tasks. Proper grounding of the solenoid coil prevents electromagnetic interference.

Graco’s modular manifold systems allow for easy scalability, enabling users to assemble multi-station valve banks tailored to specific line layouts. Optional auxiliary ports accommodate pressure sensors or pilot air feeds, offering greater control in automated feedback loops. Custom coil voltages and mounting bracket options further adapt the 115440 for specialized platforms. The low-profile design minimizes footprint in compact enclosures, making it suitable for portable spray rigs and robotic arm integrations.

Manufactured in ISO 9001 certified facilities, the Graco 115440 complies with RoHS and REACH guidelines, ensuring that materials meet global environmental and safety requirements. Each unit undergoes 100% functional testing, including leak checks under simulated load conditions and coil endurance cycles. Traceability is maintained via serial identification and batch codes, facilitating quality control audits. Detailed engineering documentation supports rapid troubleshooting and system validation. End users benefit from comprehensive technical datasheets outlining physical dimensions, electrical characteristics, and maintenance procedures.

In summary, the Graco 115440 Air Solenoid Bank Valve represents a robust solution for precision fluid control in high-performance applications. Its optimized flow path design, durable materials, and rapid actuation capabilities deliver reliable results in demanding industrial environments. Coupling this valve with proper filtration, system monitoring, and preventive maintenance routines significantly enhances operational uptime. Whether deployed in automotive paint shops, chemical dosing systems, or advanced robotics, it offers superior consistency and extended service life, reinforcing Graco’s reputation for engineering excellence.
