Process valves are used to control a media, gas or liquid, in a system. Lexair, Inc., an American third generation family-owned business, was founded in Lexington, Kentucky in 1977. Through the years, we continue to create process valves that are unsurpassed worldwide in quality. When your business is seeking process valves, there is no need to search any further than Lexair. With our commitment to excellence in products and customer service, Lexair will address your needs and deliver.

All Lexair valves are “Made in the USA”.

Process valves are typically 2-way or 3-way valves used for on/off, selecting, or diverting the liquid or gas media. Lexair Tube-O-Matic® and Poppet Valves are robust process valves that have been designed for in-line repairability and simplicity.

Lexair offers two options for Tube-O-Matic® process valves: direct pilot-operated and solenoid-pilot operated. Tube-O-Matic® valves are specifically designed for abrasive or corrosive media applications. Tube-O-Matic® process valves have been designed to include the excellent features of a pinch valve without the inherent weaknesses of a pinch valve. Lexair’s unique process valves feature an airfoil center core that facilitates high flow, fast action, and longer tube life compared to other typical process valves on the market.

Tube-O-Matic® direct pilot-operated process valves feature a tube that is controlled by an external pneumatic or hydraulic pilot pressure signal. The small tube deflection permits a high cycle rate with minimal flow noise and shock-free smooth opening or closing when using fluids. Our design features a straight-through flow path that eliminates the build-up of solids in the valve body, causing it to act as a self-flushing unit.
Tube-O-Matic® solenoid-pilot operated process valves feature a tube that is controlled by an external pneumatic or hydraulic pilot pressure via our standard solenoid operator. Much like the direct pilot-operated process valve, to close the valve, pilot pressure is applied, closing the tube around the center core and sealing bubble tight. To open the valve, pilot pressure is exhausted, allowing full flow.

Lexair Poppet Valves are also excellent process valves used to control the flow of gases or liquids. Lexair Poppet valves feature a large resilient poppet that provides bubble-tight closure, even under low pressure conditions. These valves are commonly controlled electrically via 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 directional control process valves with large flow paths that allow media to pass readily through the main body. Lexair poppet valves are used in industrial, chemical, and automation systems to open and close the fluid media flow path. Lexair Poppet valves feature a large resilient poppet that provides bubble-tight closure, even under low pressure conditions.
