Aquatrol Safety & Relief Valves

Aquatrol

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 the company. Aquatrol quickly became a recognized brand, focused on producing ASME regulated bronze safety and relief valves, servicing the OEM and quality driven marketplace.

Aquatrol manufactures ASME regulated, national Board Certified Safety valves. Section I (V) and VIII (UV) rated for steam, air, and gas applications, as well as a full line of liquid relief valves. All Aquatrol safety and relief valves go through rigid quality control, setting, testing, and re-testing to each customized application prior to the code stamping process.

All Aquatrol safety and relief valves can be custom set from inventory on an as-needed basis. Please specify series, piping size, set pressure (psi), service (steam air or gas) when ordering as well as any special options, as required.

Flow Control Management (FCM) acquired Aquatrol in May 2025 and announced the acquisition of Kingston Valves in February 2026. Kingston operations will be integrated into the Aquatrol division. Aquatrol has manufactured safety and relief valves since 1947. “Kingston valves are well known, and a nice complement to our current safety valve offering,” said Eric Lambert, President of Aquatrol. “We have found that our ability to produce complex valves and deliver them with short lead times resonates with our customers.”
