Fluoropolymer-Lined Plug Valve (X41F46)

Industrial valves and fittings dispatch fast — wear parts and complete machines quoted on request.

Lined Valves

Fluoropolymer- and rubber-lined valves for acid, alkali and corrosive service — gate, globe, butterfly, diaphragm, check and Y-strainer, DN15 to DN1200 at PN0.6–1.6 MPa. The lining is the working surface: it suits corrosive media but not abrasive slurry, and it is the part that fails if the valve is throttled or run dry. Lining grade (PTFE, FEP or PFA) and body material are confirmed per order.

Lined plug valve for on/off duty on acid and alkali lines where a ball valve's seat pocket would collect solids. A cylindrical liner-sleeved plug sits in a matching lined body bore, so the flow passage is a straight through-bore when open. Sizes DN20 to DN250 at PN1.0 MPa, flanged ends, lever or gear operation. Sealing relies on the interference fit between plug and sleeve, so torque rises with size — above DN150 specify a gear operator rather than a lever.
