Some companies immitate -- we innovate

Imitation is easy. Innovation is hard work. That’s what sets us apart.

Leighton Lee II

Leighton Lee II was an innovator. He founded our company on that spirit, and it’s how we solve tough problems today. Every product we make—from miniature check and relief valves to shuttle valves, flow controls, precision orifices and plugs—was developed to solve a customer’s fluid control challenge. Since 1948, we’ve been delivering engineered solutions for a wide variety of demanding applications. We have the experience, product breadth, and technical know-how to provide engineered performance, with zero risk.



Poppet-style Pressure Relief Valves

The latest addition to our line of cartridge-style valves offers faster opening rates, more stable flows and lower hysteresis compared to typical ball-style relief valves.
