SPARKLING Excavator Solenoid 31N6-91230

Original Quality Solenoid Valve 31N6-91230 27V DC 21W for Hyundai R Series Excavators

The 31N6-91230 Solenoid Valve (Breaker Valve) is an original quality electrical hydraulic component specifically designed for Hyundai excavators including R110-7, R140LC9, R140W7, R160LC9, R170W7A, R180LC9, and R250LC-9.

This 27V DC / 21W solenoid valve plays a critical role in hydraulic breaker (hammer) control systems, enabling or blocking hydraulic oil flow with high precision. Manufactured with premium copper coils, high-temperature insulation, and anti-corrosion coatings, this valve delivers fast response, stable operation, and long service life, even under high-frequency operations.

The Volvo DD105 die-cast compactor model is a high-precision replica of the well-known Volvo DD105 double-drum asphalt roller. Constructed with a full metal alloy body, the model accurately restores the key structural features of the real machine, including the dual smooth drums, articulated steering joint, realistic cabin interior, and signature Volvo color finish.

The drums rotate freely, and the articulation mechanism is fully movable, allowing the model to demonstrate realistic compaction and steering motions. Fine detailing on the drum edges, hydraulic components, safety guard rails, and decals provides exceptional authenticity and visual appeal.

This model is widely used for:

• Construction machinery showroom displays

• Dealer and distributor promotional gifts

• Engineering training demonstrations

• Corporate office decoration

• Collections for Volvo machine enthusiasts

SPARKLING MACHINERY can also provide a full range of construction machinery models, including excavators, loaders, haulers, graders, bulldozers, rollers, and more—covering brands such as CAT, Komatsu, Volvo, Kobelco, SANY, and Shantui.

The Volvo DD105 model offers excellent realism, durability, and professional-grade detail, making it an ideal display piece for marketing, demonstration, or collection.
