HFI has been custom fabricating hydraulic hose assemblies and hydraulic lines for four decades. Our combined experience in this field among all our engineers and specialists provides for a vast tome of knowledge and technique.
For the hydraulic fluid to do work, it must flow to the actuator and or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types. Open center circuits use pumps which supply a continuous flow. The flow is returned to tank through the control valves open center; that is, when the control valve is centered, it provides an open return path to tank and the fluid is not pumped to a high pressure. Otherwise, if the control valve is actuated it routes fluid to and from an actuator and tank. The fluids pressure will rise to meet any resistance, since the pump has a constant output. If the pressure rises too high, fluid returns to tank through a pressure relief valve. Multiple control valves may be stacked in series. This type of circuit can use inexpensive, constant displacement pumps.
The HFI manufacturing capabilities for custom rubber hydraulic hose assemblies provides for fabrication styles of almost unlimited variety. Skive and no-skive hose is used to provide lines that hold up to the roughest of environments.
HFI also manufactures their own hose ends and shells for total control over quality and value. We can provide flared ends, inverted flare, NPT, any metric style and more.
One of our specialty markets is in the boom and crane industry. We fabricate long length twin line hoses enclosed in nylon guard that run the length of boom arms. Another major market is the snowplow hose industry. We excel in the production of quality and competitive snow plow hoses.
