Lee Spring Company Lite Pressure™ Series Compression Spring LP 080V 04 S316

BACKGROUND • The Lee Spring catalog has always offered springs with relatively low spring rates or workable (maximum) loads. But often, the offered diameters (outside or inside) were too small to accommodate the intended application assembly requirements. • This new "Lite PressureTM" Series has been developed so that, for a given length and diameter (outside or inside), there would exist a series of springs that had lower spring rates or workable load ratings than what is currently offered by the existing Lee Spring Standard Series compression springs. WHY "PRESSURE"?: • Pressure is described as a force which is exerted over a surface area. In regards to compression springs, the pressure exerted as the result of a specific deflection can be more technically described as force over a flat surface with a circular perimeter (the Nominal Hole in which the spring is being used). • The term "Lite PressureTM" is used to describe a series of springs designed to be utilized where relatively low forces are required for a given diameter. HOW PRESSURE RATING FOR LP SERIES WOULD BE USED: • The pressure rating assigned to each item of the Lite PressureTM series is a selection parameter to assist in meeting qualitative requirements or quantitative requirements. • Each series is offered in a range from 1 to 5 psi pressure ratings, in 1 psi increments. POTENTIAL APPLICATIONS: • LP series springs are ideal for many fluid power applications such as relief valves, check valves or pistons • Other miscellaneous applications could include motor brushes, contacts, displays, syringes, toys, dispensers and many more MATERIAL: • LP series springs are offered ONLY in Type 316 Stainless Steel so as to provide a design that can meet requirements in various diverse applications that call for: • Improved corrosion resistance • Enhanced cleanliness • Moderately elevated temperatures RELATIONSHIP TO FLUID PRESSURE: The pressure ratings used for Lite PressureTM Series springs have no direct relationship with "pressure" as traditionally used in the fluid power industry, although indirectly the pressure ratings are conceptually equivalent. Fluid pressure would be the result of a spring force acting over the specific area exposed to the fluid and would depend on other application components such as the valve face or the piston head
