If you work with complex hydraulics or monitor their performance, scheduling regular, careful valve maintenance checks is crucial. Why? Hydraulics rely on a variable one-way fluid loop to work – much like a one-way traffic system. Without fully working directional control valves, there’s nothing to ensure pressurised liquid keeps moving, returning, and pressuring as it should.
Modular valves are found in almost every hydraulic system in use today. Like all hydraulic valves, they make sure the fluid inside the circuit flows the right way. Controlling the direction, rate, and strength of the flow of hydraulic fluid around the machine’s circuit is critical to preventing overloading, under-pressured lines and lifts, and fluid retention. Modular valves help prevent these issues, along with limiting damaging backflow and reducing the risk of O-ring seal breakage.
Every powered hydraulic machine generates ambient heat. Heat dissipates throughout the system, creating a broadly equivalent level temperature. It’s both a benefit and a hazard to engineers and designers working with volatile, sensitive mechanical systems. While the wasted thermal energy from moving hydraulics helps prevent freezing, rusting, and jams, hydraulic warmth also needs to be safely and quickly dissipated away when the machine’s fluid loop is deactivated.
Topping up the hydraulic reservoir is a vital piece of routine maintenance, because – if it is not done correctly – the ramifications are severe. A sure sign of a leaking system is one that requires make-up fluid regularly. Identifying where the system is leaking and repairing it is essential, to ensure that the system runs smoothly.
A ball valve is a simple, two-part, chambered control valve commonly used in hydraulic, pneumatic, and liquid plumbing systems. Ball valves are used to shut off the flow of liquid or gas, adjust it to a limited level, or redirect flow on a two-forked connector (when used in conjunction with another ball valve). A ball valve is omnidirectional (and can be used as such) but is usually used to control a one-way liquid or gas flow.
Hydraulics uses the movement of incompressible liquids in a confined space, to apply kinetic force to large objects. In practice, this means that a smaller, ‘trigger’ force can be converted via fluid motion into a larger ‘push’ force. The kinetic force is transferred from an initial pump into a confined chamber, amplifying the directional pressure by a factor of ten or more. Continue reading “How Do Hydraulics Work?”
When a system functions properly, operators rarely think about hydraulic valves. When hydraulic valves give a reason to think about them, it usually means they need repair or replacement! Malfunctions, leaks and breakdowns can result in unexpected expenses and downtime. Continue reading “When Should I Upgrade My Hydraulic Valves?”
