It is dedicated to the on-off control of the main nozzle air circuit, providing precise and fast switching action for the weft insertion main air flow, serving as a key component to ensure loom weft insertion efficiency and weft yarn conveying stability.
  The valve body is precision cast from aluminum alloy with high strength and impact resistance, adapting to the high-pressure air circuit conditions of the loom. It is equipped with a built-in stainless steel core and imported aging-resistant seals, ensuring excellent air tightness and sensitive response. The coil is wound with high-purity enameled copper wire with an insulation resistance of ＞20MΩ, featuring excellent insulation performance, no overheating or burnout during long-term power-on, and a service life of more than 1 billion cycles. The product uses dry and oil-free compressed air as the working medium, with a working pressure ≤0.7MPa and working temperature of -20～+40℃, adapting to the complex environment of textile workshops. With an opening time ≤8ms and closing time ≤21ms, it has fast response speed, enabling precise timing control of weft insertion air flow, effectively reducing weft breakage, weft deviation and fabric defects.
  Produced with a 1:1 replica of the original Toyota standard, the air interface and mounting hole position are identical to the original part, enabling direct replacement without loom modification. The overall performance parameters match the original part with stable and reliable operation, making it a cost-effective original-equivalent replacement solution for daily maintenance and part replacement of Toyota 710 series air-jet looms in textile mills.

Applications:

• This J3115-41120-00/J3115-41171-00 Main Solenoid Valve is a core pneumatic control accessory for the weft insertion system of Toyota 710 series air-jet looms, widely used in loom main nozzle air circuit control, serving as a key component to realize weft insertion main air on-off and ensure weft yarn conveying stability.
  It is mainly suitable for the production of various cotton, chemical fiber, blended and high-count high-density fabrics, especially for continuous weaving conditions of high-speed air-jet looms. By precisely controlling the on-off timing of weft insertion air flow, it can effectively reduce weft breakage, weft deviation and fabric defects, improve weaving continuity and yield rate, and extend the service life of loom weft insertion system components.
  It is widely used in daily maintenance, batch part replacement and old equipment upgrading of Toyota 710 series air-jet looms in textile factories. It can perfectly replace original main solenoid valves of the same specification, restore loom weft insertion control accuracy, and reduce downtime losses caused by solenoid valve failures, serving as a necessary consumable accessory for Toyota air-jet looms in large and medium-sized textile enterprises.
