Key Insights on Hydraulic Multi-Directional Control Valves

Hydraulic multi-directional control valves – often called multi-way valves or directional control valves – are the unsung heroes inside agricultural machines, construction equipment, sanitation trucks, and other mobile machinery. They allow operators to control multiple hydraulic functions (cylinder

ISO VG 32 Vs 46 Hydraulic Oil: Choosing The Right Viscosity for Your Hydraulic Equipment

Selecting the correct hydraulic oil viscosity is crucial for anyone purchasing or maintaining hydraulic machinery. Buyers and procurement decision-makers for equipment like hydraulic pumps, hydraulic motors, cylinders, and valves must ensure their hydraulic systems get the right oil. Using the wrong

Internal Vs External Gear Pumps

Internal and external gear pumps (Spanish: bomba de engranajes interna/externa; Russian: шестеренный насос внутреннего/внешнего зацепления) are two fundamental types of hydraulic gear pumps. Both use interlocking gears to move fluid, but their designs and performance characteristics differ in key wa

Why Hydraulic Systems Show Normal Pressure But Lack Power

Hydraulic systems are the muscle of industrial machinery – from hydraulic motors in excavators to presses driven by hydraulic pumps and valves. Yet a perplexing issue can arise: the pressure gauge reads normal (or even high), but the machine feels weak or won’t do work. Imagine a hydraulic cylinder

Why Does My Hydraulic Motor Keep Rotating After Shutdown?

When you turn off a hydraulic system, you might expect every moving part—especially the hydraulic motor—to stop immediately. However, many operators notice that a hydraulic motor sometimes continues spinning for a short time after shutdown. Is this normal or a sign of trouble? In this article, we’ll

Hydraulic Motor Overheating: Causes, Solutions & Prevention

Hydraulic motors (like hydraulic pumps) are major heat sources in hydraulic systems. Some heat is unavoidable, but excess heat represents wasted energy and reduced efficiency. Under heavy load or improper conditions a hydraulic motor will overheat, degrading its performance. This guide explores t

Directional Hydraulic Valve Mid-Position (Neutral) Functions: O, H, M, Y

In hydraulic systems, directional control valves route pressurized oil to actuators, and the valve’s neutral (mid) position plays a crucial role in system behavior. The neutral position defines how the four ports (pressure P, tank T, and work ports A/B) connect when the valve spool is centered. Fo
