Plug Valve

Streamlined body, combined floating-ball disc with cone-shape sealing surface, these insure no abnormal vibration and noise when the valve is in use. These can also reduce pressure loss,makes the scope of upstream pressure much wider than other pressure valves and pressure output more stable. Widely used in potable water supply, building construction and so on.
Unique design
Streamlined body. Combined floating-ball valve clack. Cone-shape sealing surface.
Diaphragm type control. Filter installed at the pipe system. Screw hole at the bottom can clear the sediment.
Excellent proof corrosion characteristics
Internal and external epoxy resin coating. Floating-ball and filter are both made of bronze.
Reliable hygiene principles
Epoxy resin and rubber comply with hygiene standard. Sealing material are made of rubber and PTFE. Trims are made of stainless steel or bronze.
