Valvesonly is one of the famous Dual Plate Check valve manufacturer in USA. Dual Plate Check Valves are all-purpose non-return valves that are much stronger, lighter, and smaller in size than traditional swing check valves or lift check valves. They’re ideal for flowlines, manifolds, pipeline transmission and distribution, pressure regulation and metering runs, underground storage, hot tapping, water flooding, and general pipeline service.

Dual Plate Check valves are available in cast form. Valves are with single piece body construction with flanged, butt weld, wafer, solid lug ends. Two spring-loaded plates are hinged on a central hinge pin in the Dual Plate Check Valve. When the flow reduces, the plates close due to the action of the torsion spring before the flow reverses.

Advantages of Dual Plate Check valve:

  • No Water Hammer
  • No Slamming
  • Flexible installation
  • Reduced seat face wear and tear.
  • More compact and structural sound design
  • Long life and trouble-free operation
  • Under most flow and pressure conditions, the seal is efficient and positive.

Application of Dual Plate Check valve:

  • Water systems include boilers, potable water, fire protection systems, and cooling and heating water systems.
  • Hydrocarbon: In almost all the applications.
  • Chlorine, Hydrogen, Nitrogen, Carbon Dioxide, and Oxygen are examples of air and gas applications.
  • Sugar, pharmaceuticals, paper, cement, steel, aluminium, copper, and zinc are examples of metallurgical and chemical applications.
