Product Name: SHACMAN Delong F3000 Pressure Limiting Valve (Pressure Regulator Valve)
OEM Number: 81.52101.6269
Brand: SHACMAN (Shaanxi Automobile Group) / Equivalent OEM Grade
Application: SHACMAN Delong F3000, X3000, M3000, M3000S series heavy-duty trucks

Overview

The SHACMAN Delong F3000 pressure limiting valve with OEM number 81.52101.6269 is a critical hydraulic system component that acts as the vehicle's "hydraulic pressure regulator," maintaining stable system pressure within safe operating limits. It automatically cuts off pressure buildup when the preset value is reached and replenishes pressure when system pressure drops, effectively preventing overpressure damage to pipelines, pumps, and other hydraulic components. Even under heavy loads, continuous operation, or sudden load changes, it maintains consistent pressure output to keep the vehicle running smoothly. This valve excels in harsh conditions, including long-haul transportation, mining operations, construction sites, and mountainous terrain driving.

It can be installed directly as a bolt-on replacement, requiring no welding or structural modifications. For guaranteed fitment, we offer accurate part matching services based on the vehicle's VIN code.

Key Advantages

• Functions as the hydraulic pressure regulator of the vehicle, precisely controlling and stabilizing system pressure within a safe operating range.

• Prevents overpressure damage to pipelines, pumps, and other hydraulic components.

• Maintains consistent pressure output even under heavy loads, continuous operation, or sudden load changes.

• Standardized interface size and mounting dimensions for bolt-on installation without welding, drilling, or structural modifications.
