Pressure Relief Valve for Paver Track Tensioning Grease
1. Core Purpose:
Its primary function is to protect the track tensioning cylinder and seals from being damaged by excessive pressure. When grease is pumped into the grease nipple to adjust track tension, this valve acts as an automatic overflow.
2. How It Works:
The valve is typically built into the grease fitting housing or the cylinder itself.
It has a pre-set cracking pressure (e.g., 250-300 bar, depending on the model).
During tensioning, if the grease pressure exceeds this safe limit—which can happen if the track is fully tight but pumping continues, or due to thermal expansion—the valve opens automatically.
It vents the excess grease, preventing pressure from rising further and potentially blowing out seals or damaging the cylinder.
3. Key Benefit:
It provides a fail-safe, preventing costly damage to the tensioning assembly and avoiding track over-tensioning, which can lead to
excessive wear on rollers, sprockets, and the track chain itself.
