Отрицательный провод аккумуляторной батареи шасси Caterpillar 6622403

The Pump Block Relief Valve controls pressure within the pump’s fluid circuit. Installed in the pump block, this valve opens when system pressure exceeds a preset limit, allowing excess fluid to divert safely back to the reservoir line. This action prevents damage to pumps, hoses, and connected actuators caused by pressure spikes. The valve operates automatically, responding to fluid pressure without needing electronic controls.Attributes:• Reduces the risk of oil leakage due to over-pressurization.• Supports return flow to the tank without disrupting the main circuit function.• Prevents cavitation by maintaining steady back pressure during relief.Applications: The Pump Block Relief Valve is installed near the pump housing or block manifold to regulate pressure by redirecting excess fluid safely out of the circuit when thresholds are exceeded.
