Expertise
Meet the engineer behind every LAUX valve
Mr. Liu — Founder & Chief Engineer
“I have worked in industrial valves since 1995 — from disc design and seat vulcanisation to AWWA C504 wall-thickness specs. LAUX was started in 2011 to build the butterfly valve I always wished I could buy: tight bidirectional sealing, low operating torque, a 24-month warranty, and a factory phone number the customer can call when something matters.”
