SPARKLING E235BSR Hydraulic Valve – Precision & Durability

Precision Hydraulic Control Valve for E235BSR Series Crawler Excavators
Engineered for E235BSR, E235BSRLC, and E235BSRNLC crawler excavators, the Hydraulic Control Valve (YF30V00011F1/F3/F4) is the intelligent nerve center of your machine’s hydraulic system. This OEM-compatible valve integrates advanced flow distribution and pressure regulation technologies, enabling seamless coordination of multiple actuators (boom, arm, swing, travel) under heavy loads. Featuring hardened spools with laser-etched metering profiles and triple-layer Nitrile seals6, it minimizes internal leakage, reduces heat generation, and eliminates sudden pressure drops during complex compound operations. Rigorously tested to exceed 500,000 cycles at 350 bar4, SPARKLING MACHINERY’s valve ensures precise controllability in demanding applications – from trenching to lifting – while extending pump life by stabilizing system pressure fluctuations.

   SPARKLING MACHINERY NEW PC27MR PC30MR PC35MR PC45MR PC490 PC55MR 708-3S-14290/708-3S-14250 Piston Subassembly is a dedicated, high-performance hydraulic component exclusively engineered for KOMATSU PC27MR, PC30MR, PC35MR, PC45MR, PC490, and PC55MR crawler excavators—covering mini to heavy-duty models widely used in urban construction, landscaping, mining, and large-scale infrastructure projects. As a core part of the excavator’s hydraulic cylinder system, it converts hydraulic pressure into linear motion to drive key mechanisms (boom, arm, bucket), ensuring powerful and smooth operation during tasks like trench digging, rock breaking, and material loading. This function is vital for maintaining sufficient digging force, optimizing operational efficiency, and avoiding unplanned downtime caused by cylinder performance failures.

• Function: Operates within the hydraulic main pump (typically the LPD28 or LPV30 models) to control fluid displacement and system pressure.
• Dimensions: Approximately 22mm x 40mm.
• Compatible Equipment: Primarily used in Komatsu "MR" series mini-excavators:
  • PC27MR, PC30MR, PC35MR, PC40MR, PC45MR, PC50MR, and PC55MR.

   SPARKLING MACHINERY NEW 7114-12630 Brake Plate EW130 is a premium China-made safety component specifically engineered for EW130 wheel excavators. As a critical part of the braking system, it works in tandem with brake discs to create controlled friction, enabling smooth and reliable deceleration and stopping of the machinery during operation, maneuvering, and emergency scenarios.

   Designed to original equipment standards, it maintains consistent friction performance and heat resistance, operating reliably even under frequent braking cycles and heavy-load conditions. With optimized surface design for uniform force distribution, it adapts seamlessly to harsh working environments, from dusty construction sites to wet terrain. Backed by strict quality verification, it guarantees stable performance to support safe and uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 31Q7-51120 Cylinder Assy, RH Boom is a core hydraulic actuator for Hyundai excavators (construction/mining use). It drives the right-hand boom’s lifting and lowering, ensuring stable force output for heavy-load operations. 
   Meeting Hyundai OEM standards (31Q7-51120), it resists -30°C to 100°C temps, high hydraulic pressure, and wear, guaranteeing seamless compatibility and long-term reliable boom control performance.
