Frequently Ask Questions
A Single Seated Lined Control Valve is a globe-type control valve with one main plug-and-seat arrangement and a corrosion-resistant lining on the process-contact surfaces.
Alis Valves manufactures and supplies lined control-valve solutions for chemical, petrochemical, fertilizer, pharmaceutical, water-treatment and other corrosive industrial applications, with fluoropolymer-lined configurations such as PTFE, PFA and FEP, depending on the required service.
The valve uses one primary seat and plug arrangement. This provides good control characteristics and reliable shut-off compared with many double-seat arrangements.
The lining acts as a protective barrier between the corrosive process fluid and the metallic valve body, reducing corrosion of the underlying body.
