Precise Pressure Control & System Protection
The core function of the relief valve is to quickly open and release excess pressure when the hydraulic system pressure exceeds the set value. This effectively prevents serious failures such as hose bursts, pump damage, and valve body destruction caused by overloading, protecting the machine's core hydraulic components.
Optimized for Kobelco Equipment
This part is specifically designed for Kobelco SK135SR and SK140-8 models, ensuring perfect compatibility with the original hydraulic system and guaranteeing reliability and stability after installation.
Built for Demanding Conditions
As a critical component of an excavator's hydraulic system, this valve is manufactured to high standards. It is designed to withstand the high pressures, high-frequency vibration, and harsh environments typical of construction machinery operations, offering excellent durability and a long service life.
