YN22V00014FA Hydraulic Swing Relief  Valve For SK200-8 SK210LC-8  Kobelco Excavator

Restore Precise Swing Control & Protect Your Hydraulic System from Overload

Ensure smooth, powerful, and protected upper-structure rotation with the genuine YN22V00014FA Hydraulic Swing Relief Valve. This critical hydraulic component is engineered as a direct OEM replacement for Kobelco SK200-8 and SK210LC-8 excavators. A properly functioning relief valve is essential for controlling swing motor pressure, preventing damage from shock loads, and maintaining precise operator control. Don’t let a faulty valve lead to sluggish swing, uncontrollable drift, or catastrophic hydraulic system failure.

Product Overview

The YN22V00014FA Hydraulic Swing Relief Valve is a key safety and control device within your excavator’s swing circuit. Its primary function is to limit the maximum pressure in the hydraulic lines supplying the swing motor, protecting it and associated components from damage caused by sudden stops, inertial loads, or external forces. This valve ensures smooth deceleration and controlled swing operation. Our replacement YN22V00014FA is manufactured to exact OEM specifications for cracking pressure, flow characteristics, and physical dimensions, guaranteeing reliable performance and seamless integration into your machine’s hydraulic system.

Key Features & Benefits

• Precision Pressure Regulation: The YN22V00014FA is calibrated to open at a specific, pre-set pressure, effectively limiting peak system pressure to protect the swing motor, hydraulic lines, and pump from damage due to overloads and shock.

• Perfect OEM Compatibility & Fit: Engineered as a direct replacement for part number YN22V00014FA, ensuring perfect physical fitment, port alignment, and hydraulic performance for your Kobelco SK200-8 or SK210LC-8.

• Ensures Smooth & Controlled Swing Operation: By managing pressure spikes during swing start/stop, this valve contributes to stable, predictable, and precise upper-structure rotation, enhancing operator control and productivity.

• Critical System Protection: Acts as a vital safeguard, preventing expensive failures in the swing motor, gearbox, and main hydraulic pump by diverting excess pressure back to the tank.

• Durable Construction for Demanding Environments: Built with high-grade materials, precision-machined components, and robust seals to withstand continuous high-pressure cycles, vibration, and fluid contamination.

• Restores Factory Performance: Replaces a worn or faulty valve that may be causing slow swing, swing drift, unusual noises during rotation, or system overheating due to constant relief flow.

Frequently Asked Questions (FAQ)

Q1: What are the symptoms of a failing swing relief valve (YN22V00014FA)?
A: Common signs include:

• Slow or Weak Swing: Loss of swing power or speed.

• Swing Drift: Inability to hold the upper structure stationary.

• Unusual Noises: Knocking or chattering sounds during swing deceleration.

• Hydraulic Overheating: System runs hot due to the valve constantly bypassing fluid.

• Shock or Jerk During Swing Stop: Lack of smooth deceleration.

Q2: Where is this valve located on my excavator?
A: The YN22V00014FA is typically integrated into the swing motor manifold or mounted directly on the swing motor itself. Consult your machine’s hydraulic schematic or service manual for the exact location.

Q3: Is professional installation and calibration required?
A: Yes, strongly recommended. Installation requires depressurizing the hydraulic system, precise cleaning to prevent contamination, and proper torque specifications. More importantly, the valve’s cracking pressure may need verification or adjustment with a hydraulic pressure gauge after installation, a task for a qualified technician.

Q4: Can a faulty relief valve damage other components?
A: Absolutely. A valve stuck open can cause slow swing and system overheating. A valve stuck closed or set too high fails to protect the system, leading to extremely high pressure spikes that can damage the swing motor, pump, and hydraulic lines.

Q5: Is this a genuine Kobelco part?
A: This is a high-quality, OEM-compatible replacement valve manufactured to the exact specifications of the original YN22V00014FA part, ensuring reliable performance and correct hydraulic function.
