How to pinch the advantage in solenoid valve performance
For solenoid valves used in miniature hydraulic applications, such as those found in the medical, chemical and scientific sectors, there’s always a need to meet a number of important prerequisites. From our extensive experience across a multitude of industries, we know that reliability is primary among them. Particularly vital is tolerance to contamination within the flow stream, as this attribute makes a major contribution to the maintenance-free, trouble-free operations that keep end users content. With these thoughts in mind, our team of expert engineers here at The Lee Company set about developing the LFY2 series of 3-way pinch solenoid valves.
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®.
