Explore the various hydraulic applications across industries such as agriculture, construction, manufacturing, and more. Learn about how hydraulic systems play a an important role powering heavy machinery, enhancing efficiency and driving innovation into different fields.
Quick Overview A differential-acting sequence valve uses a piston with two unequal working areas, instead of a spring-loaded spool or poppet alone, to open a secondary circuit once the primary circuit reaches a set pressure. The HFD VDSD/B applies this principle to stay accurate even when the outlet side sees back pressure — without needing […]
Aircraft and oceangoing vessels share a design problem that has nothing to do with how they move and everything to do with what happens when something breaks: neither can be allowed to lose steering or braking control mid-operation. Both industries independently arrived at the same mechanical answer — the shuttle valve — to isolate a

A single tractor or combine hydraulic pump often has to feed several jobs at once — steering, a loader, a three-point hitch, and whatever implement is attached behind it — and none of those jobs need the same pressure. A planter’s down-force cylinders need a light, precisely controlled push measured in a few hundred psi.

Quick Overview: Double Pilot Operated Check Valve in AWP Leveling Systems What does a double pilot operated check valve do in an aerial work platform? It locks each leveling or outrigger cylinder in position — in both the extend and retract directions — so the platform chassis stays level once set, even as the load

Quick Overview: Three-Way Flow Control Valves A three-way flow control valve (also called a three-way speed control valve or overflow-throttle type flow control valve) has three ports: pressure inlet (E), priority load outlet (P), and bypass/return (T or B). It combines a manually adjustable throttle with a differential-pressure compensation valve to keep flow to the

Quick Overview: “Dump truck valve” is not one part — it’s a system of several distinct valves working together. The main ones are the directional control valve (routes fluid to raise or lower the bed), pressure relief valve (protects the circuit from overpressure), check/load-holding valve (stops the bed from drifting down under load), counterbalance valve

Quick Overview An overcenter valve is a load-holding valve mounted directly on a hydraulic cylinder to stop the cylinder from moving unless commanded — it is also called a counterbalance valve or motion control valve. On truck-mounted cranes, a single overcenter valve is fitted to each single-acting outrigger cylinder to prevent the leg from settling
Refuse collection trucks are among the most hydraulically demanding vehicles in daily municipal and commercial service. A rear-loader compactor running a full shift may complete several hundred compaction cycles before returning to the depot. Each cycle drives the packer blade cylinder to near-maximum extension, compressing waste into the hopper body. The ejection cylinder makes its
Mini excavators and compact loaders are designed to work across multiple functions simultaneously — digging, grading, lifting, and driving attachments — all from a single hydraulic power source. This efficiency comes with a challenge: not every circuit in the machine requires the same pressure. Auxiliary circuits that power attachments such as hydraulic breakers, augers, grapples,

Quick Overview What is a direct acting back pressure proof sequence valve? A direct acting back pressure proof sequence valve is a hydraulic pressure control component that opens at a preset pressure to direct fluid to a secondary circuit, while remaining unaffected by fluctuating back pressure in the return line. It operates without external pilot
