Zeron Fastners
Industrial Valves & Fasteners3-Way & 4-Way Multiport Plug Valves
Multiport Plug Valves (3-Way and 4-Way) are versatile quarter-turn valves engineered to direct, divert, blend, or isolate multiple fluid streams using a single compact valve body. By replacing two or three standard two-way valves, tees, and associated pipe spooling, Zeron Fastners multiport plug valves significantly reduce system footprint, installation costs, and prospective leak paths.
Available in both 'L-Port' (diverting) and 'T-Port' (mixing/diverting) configurations, our multiport plug valves feature premium virgin PTFE sleeves or precision-machined lubricated tapers. They operate smoothly with low torque and deliver bubble-tight bi-directional shutoff in chemical refining, wastewater distribution, bulk chemical transfer, and heating loops.
