Product Overview

The Kobelco Air Compressor Intake Valve Assembly (Part Numbers: 1000219819 / P-GA01-501#03 and 1000049802 / P-GA01-501#05) is a critical air control component designed specifically for Kobelco rotary screw air compressors. It regulates intake air volume during load/unload operating cycles, maintaining system pressure stability and preventing oil backflow during emergency or routine shutdowns.

Manufactured to meet rigid OEM standards, these intake valves feature heavy-duty valve bodies, wear-resistant internal pistons, and precision sealing components. They serve as reliable direct replacements for maintenance, overhaul, and emergency repairs across industrial compressed air systems.

3. Key Features & Benefits

• Precise Load / Unload Air Flow Control：

  Provides fast and accurate responsiveness during loading and unloading cycles, reducing energy consumption and optimizing air end performance.

• Integrated Non-Return / Anti-Reversal Protection:

  Prevents compressed air and lubricant oil from reversing back into the air intake filter when the compressor stops, avoiding air filter contamination.

• 100% Direct Fit & OEM Compatibility:

  Precision-engineered to align perfectly with original Kobelco mounting dimensions, internal porting, and pneumatic control lines for seamless plug-and-play replacement.

• Durable Industrial Construction:

  Constructed with high-strength alloy materials and temperature-resistant seals, designed to endure high thermal stress, pressure fluctuations, and continuous heavy-duty service.

5. Common Symptoms (When to Replace?)

Consider replacing or overhauling your Kobelco intake valve if you notice any of the following issues:

1. Failure to Load or Unload: Piston sticking or internal seal wear preventing the valve from opening/closing properly.

2. Oil Reversal / Backflow to Air Filter: Check valve seal failure allowing oil and air mixture into the intake air filter upon shutdown.

3. Air Leaks & Sluggish Action: Worn-out seals or degraded internal diaphragms leading to continuous air blowing or slow valve response.
