152301000374A Hydraulic Dual-Circuit Brake Control Valve Block for Sany SAT40C

The 152301000374A Brake Valve Block (Hydraulic Brake Manifold Assembly) is the primary pressure-distributing and fluid-regulating control center designed for the wet-disc braking system of the Sany SAT40C articulated dump truck. Articulated haulers carry up to 40 tons of payload down steep, slippery mining grades, making reliable braking performance a critical safety requirement. This multi-valve manifold block receives high-pressure hydraulic oil from the triple gear pump set (150107020054A) and the stored nitrogen energy in the accumulators (60308391). Based on the driver’s brake pedal inputs, it regulates and divides pressure flows precisely between the front tractor and rear trailer axles.

This advanced manifold block integrates a Two-Position Three-Way Solenoid Directional Valve (152301000374A004) to electronically engage or override the parking brakes, a Pilot Operated Pressure Reducing Relief Valve (152301000374A003), and a secondary Pressure Reducing Valve (B220401000491) to maintain stable hydraulic pressures. Internal routing and flow logic are managed by a Pilot Unloading Valve (152301000187A004), a Hydraulic Control Reversing Valve (152301000187A003), a Logic Valve (152301000187A002), and five independent Check Valves (152301000374A002) to prevent reverse-fluid pressure drops. We supply the fully integrated 152301000374A brake manifold block as well as all individual solenoid and valve cartridge inserts. Both genuine Sany OEM components and high-integrity aftermarket alternatives are ready for B2B export shipment globally.

General Assembly Specifications

152301000374A Assembly Component Parts List

Below is the detailed parts catalog breakdown of the hydraulic brake valve block as referenced in the Sany SAT40C technical manual. All listed valve cartridges are orderable separately for targeted manifold servicing:

Features & Benefits of Our Brake Valve Block

• Electronic Parking Lock Integration: Equipped with a robust Two-Position Three-Way Solenoid Valve (152301000374A004) to manage the engine’s electronic parking brake engagement, acting as an electrical safety override.
• Multi-Stage Pressure Regulation: Features integrated pressure reducing (B220401000491) and relief (152301000374A003) valves to regulate high system inlet pressures down to safe, progressive braking thresholds, preventing seal ruptures in the brake cylinders.
• Precise Flow Reversing & Logic: The internal logic (152301000187A002) and reversing (152301000187A003) valves provide smooth hydraulic oil redirection, ensuring that brake pressures are balanced evenly across the tandem axles.
• Fluid Back-Flow Isolation: Outfitted with five check valves (152301000374A002) to block oil from leaking backward through the ports, maintaining continuous system pressure and preventing spongy pedal responses.
• Monoblock Cast Manifold Housing: The main block manifold is machined from low-porosity, high-tensile material, maintaining exact internal bore alignment under continuous high operating pressures and temperature cycles.

Ordering & Technical Maintenance Guidelines

1. Verify Pressure Setting Calibrations: Brake pressure reducing and relief valves are calibrated to specific factory pressure ratings (MPa/PSI). Please provide your Sany SAT40C’s chassis serial prefix so our technical team can verify the exact cartridge pressure settings before shipping.
2. Always Renew Gaskets and O-rings: Valve cartridges utilize specialized polyurethane or nitrile O-rings and backup rings to seal. Always install fresh, pre-lubricated seals whenever a valve cartridge is removed or replaced to prevent high-pressure external oil leaks.
3. Ensure Cleanliness on Installation: High-pressure proportional hydraulics are highly vulnerable to particulate contamination. Keep the block port caps on until the exact moment of connecting the steel hoses, and clean the cartridge cavity thoroughly to prevent dirt from binding the valve spools.
