Aquatrol Valves

Aquatrol was founded in 1947 by Lyman J Lowden, who owned an engineering firm specializing in the development of municipal power, steam and water filtration systems. During LJ’s tenure he discovered a need within the safety and relief valve markets and founded our company. Aquatrol quickly became a recognized brand, focused on producing ASME regulated bronze safety and relief valves, servicing the OEM and quality driven Safety Valves, Relief Valves, Safety Relief Valves and Pressure Relief Valves from Aquatrolmarketplace.
