Hydraulic Pressure Gauges & Single/Double-Acting Valves for Concrete Pump Trucks

12/03/2026

During the operation of boom concrete pump trucks, the hydraulic system plays a crucial role, directly determining pumping efficiency, stability, and equipment lifespan. Hydraulic pressure gauges and single-acting – double-acting hydraulic valves are essential spare parts that must be used according to technical standards and correct specifications.

VIPEC – a specialized supplier of genuine concrete pump truck spare parts, provides integrated, safe, and long-term cost-effective solutions for customers.

1. Hydraulic Pressure Gauges – Essential Monitoring Devices on Concrete Pump Trucks

Name: Hydraulic Pressure Gauge Port M1 / M3 / M8

Hydraulic pressure gauges monitor the system’s operating pressure, helping operators to:

Monitor pump and cylinder status
Detect abnormal issues early
Adjust pumping mode according to construction load

🔹 Port M1 – Main Pump Pressure

Pressure generated by the main pump to operate the main hydraulic cylinders

Pressure varies with concrete load

Maximum pressure: 360 bar

🔹 Port M3 – S-Valve Shift Pump Pressure

Maximum pressure: 190 bar

Standard Nitrogen pressure: 90 – 100 kg

When Nitrogen > 60 kg → additional pumping is required to ensure stability

🔹 Port M8 – Flow Control Pressure

Pressure range: 6 – 24 bar

Controls the swash plate angle of the main pump

Determines fast – slow pumping speed

Directly adjusted by volume on the Remote

Pressure gauge configuration for Everdigm boom pump trucks

Filter clogging indicators: 03 units

400 bar hydraulic pressure gauges (M1, M3): 02 units

60 bar hydraulic pressure gauge (M8): 01 unit

60 bar hydraulic pressure gauge – bottom mount (M8): 01 unit

Origin: South Korea

Using genuine hydraulic pressure gauges helps concrete pump trucks to:

Operate stably and accurately

Reduce the risk of pump and cylinder damage

Minimize downtime at the construction site

Optimize long-term maintenance costs

2. Single-acting – Double-acting Hydraulic Valves: Spare Parts for Controlling Concrete Pumping Stroke

Single-acting Valve

Double-acting Valve

Name: Single-acting – Double-acting Directional Hydraulic Valve

Classification

Single-acting hydraulic valve
Double-acting hydraulic valve

Brand: Rexroth (Germany)

Origin: South Korea

Material: The valve is machined from special wear-resistant, high-pressure metal, suitable for the harsh working environment of concrete pump trucks.

Function

Reverse the main hydraulic cylinder
Change the pumping stroke
Ensure continuous and accurate concrete suction – discharge cycle

Installation Location

Installed in the FFH block
Located above the main hydraulic cylinder

Service Life

Long lifespan: Depends on operating conditions and hydraulic oil quality

3. Comparison of Genuine Hydraulic Spare Parts and Unbranded/Counterfeit Goods

Criteria	Genuine Parts	Unbranded/Counterfeit Goods on the Market
Compatibility	Perfectly compatible with pump truck	High error margin, prone to jamming – leakage
Durability	High, stable pressure resistance	Wears quickly, easily damaged
Accuracy	Accurate pressure display and control	Large error margin, difficult to control
Operational Risk	Low	High, easily damages pump – cylinder
Downtime	Minimized	Increased due to continuous repairs
Long-term Cost	Cost-effective	Expensive due to frequent replacements

Actual operation shows that using unbranded/counterfeit parts may be cheaper initially, but leads to significant losses in terms of time, labor, and equipment during construction.
