We offer excellent customer service, product engineering, component machining and manufacturing in our modern state-of-the-art facility in Lexington, Kentucky. Since 1977, we have continually expanded our product offerings including our unequalled selection of poppet valves and we continue to design and manufacture new or modified items to meet the special requirements of our customers.
Lexair Poppet valves are “Made in the USA.” All our castings are made to our specifications by USA foundries. All machining and assembly is done by Lexair employees at our Lexington, KY factory.
Poppet valves are fundamentally different from ball, spool, or diaphragm valves. Poppet valves are used in pneumatic and hydraulic systems. These valves are commonly controlled electrically through solenoids or direct pilot operated with pressurized fluids. Poppet valves may be either normally-closed (NC) or normally-open (NO) in their de-energized states.
Poppet valves are often used in industrial, chemical, and other quick reacting processes, due to the characteristic of the poppet valve being a high flow, fast-acting valve. Poppet valves are directional control valves, with large flow paths to allow media to pass through the main body of the poppet valve. Lexair poppet valves are used in industrial, chemical, and automation systems to open and close the fluid media flow path.
Poppet valves are used to control the opening and closing of gases or liquids in a system. Sometimes referred to as Media Separated Valves or Air Piloted Media Separated Valves, Lexair Poppet valves completely isolate the pilot media from the main (controlled) media. Media Separated Valves can be safely used to handle corrosive chemicals and aggressive media.
Lexair Poppet valves are constructed of non-corrosive materials so they can be used with a wide range of liquids and gases where quick-acting control is required. Working pressure to 500 PSI is standard, higher pressures are available upon request at Lexair. Poppet valves are characterized by having a movable element (the poppet) that acts on a seat. A seal is typically housed in the poppet of our valves. The poppet and seat are used for bubble-tight control of the flow of a liquid or a gas through the valve body.
Lexair Poppet valves feature a large resilient poppet that provides bubble-tight closure, even under low pressure conditions. Internal components made from bronze, brass and stainless steel plus a wide choice of seal materials to assure excellent compatibility with a broad range of media. These valves are available with a variety of pilot-to-line-pressure ratios. Lexair Poppet valves feature fast in-line repair. The body does not have to be removed or the plumbing disconnected to accomplish repairs. In-line repair keeps down-time to a minimum saving you money.
