Fusing performance with safety
What happens when the flow rate in your hydraulic system increases beyond its specified function? Well, in such instances a hydraulic breach is the likely culprit and your system could be facing catastrophic failure. After all, when damage occurs to a hydraulic circuit, there is typically a fast flow of fluid towards the breach. The consequence is a rapid loss of fluid pressure leading to system failure and the potential for components such as actuators to collapse. This situation is undeniably dangerous in critical applications such as aerospace landing gear and brakes, high-lift systems, thrust reversers, engine air-bleed mechanisms and down-hole equipment for the oil industry.
Give contamination a wide berth
When it comes to the provision of effective flow restriction for precision micro-hydraulics, there are a number of key factors that you simply cannot afford to overlook. For instance, in applications where contamination is a concern, high levels of reliability become a priority. Here at The Lee Company we listen carefully to the requirements of our customers and their particular challenges, which is precisely why we’ve developed the new High-Pressure 250 Visco Jet®.
Fact-checking the latest miniature valve technology
Finding both high-flow and high-pressure capability in compact ball-style check valves has long been an issue for fluid system designers. But search no more. Thanks to the new family of HFS (High Flow Slotted) LeeCheck® check valves from The Lee Company, the complete flow and pressure requirements for a host of important fluid systems can now be met. Not only do our HFS LeeChek® valves offer three times more flow capacity than similar ball-style check valves, they’re also rated for system pressures up to 5,000 psi (344 bar). All in a significantly smaller package.
Nanoliter dispense valves increase performance of semiconductor production equipment as node sizes drop
As semiconductor node sizes drop below 10 nanometers and wafer test cells demand greater efficiency and throughput, semiconductor equipment manufacturers need to dispense and meter small volumes of critical fluids under intense operating conditions. These high-performance systems demand field-proven fluidic components capable of near-digital response. Additionally, as chip volumes increase, high-reliability solutions are required to maximize production line uptime.

Houston, we have a problem - call The Lee Company
In the space industry there exists a number of key market drivers, among the most important of which is fuel economy. Fuel is expected to last for long space missions, as there will unlikely be any opportunities to fill up on route! The upshot is that fluid system components for space vehicles need to be both lightweight and compact, without compromising vital design requirements such as reliability and safety.
Think big, design small
Designing fluid control systems for use in compact spaces often engenders its own set of challenges, with some designers concerned that miniature innovations somehow represent a compromise in performance. And yet, assuming you pick a reliable technology partner, nothing could be further from the truth.
Pumping up precision in medical and scientific applications
There are certain tasks, in certain industries, which demand that little bit more when it comes to precision, and pumping is no exception, particularly within the fluidic systems deployed by the medical and scientific sectors. A dispense pump can be the system’s most essential component, which is precisely why our engineers here at The Lee Company have developed the class-leading LPD series of precision dispense pumps.
Small-footprint solenoid valves offer big performance
Engineers are frequently tasked with designing portable or stationary instruments that have to meet highly demanding size, power and weight limitations. Nothing unusual in that, you might think. Well, yes, except there’s a caveat. These objectives must be met without sacrificing core attributes such as system-level performance and quality.
Solenoid valves in full flow
As engineers, we sometimes need that little bit more when it comes to the performance of our engineering components. OK, so this requirement is usually application dependent, but there are plenty examples in industry today that demand performance levels over and above that offered by standard products. And this includes solenoid valves.
Oil and gas industry plugs into the latest seal technology
As oil and gas wells continue to forage deeper and deeper, drilling, completion and production equipment is subject to ever-increasing hydrostatic pressures. What’s more, when equipment returns to the surface, pressure may remain within the tool, thus requiring a safe purging process.
The medical device industry’s quiet solenoid valve
Have you ever been frustrated by the inherent clicking noise that emanates from an energised solenoid valve?
