Flowserve NAVAL

NAVAL Recognized as a leader of ball valves, Naval valves are common as a closing device for thermal energy power stations and district heating networks.

Naval ball valves are fully welded, free from all service and there is no need for any spare parts. This design facilitates an easy installation and isolation. All valves can be equipped with electrical or pneumatic actuators and the valve with actuator can be delivered according to the requirements of the ATEX directive (94/9/EC) to equipment group II if specially required.

The sizes of Naval valves range from DN 10 to DN 600 and pressure ratings from PN 16 to PN 40, also Class 150 and Class 300. The operational temperature range is from -40°C to 200°C (steam to 250°C).

Features

  • Steel ball valves are designed for District Heating (CHP) installations, Heat Transfer piping, oil lines and oxygen-free water lines.
  • Full bore ball valves are designed for District Heating (CHP) installations, Heat Transfer piping, oil lines and oxygen-free water lines.
  • Long stem ball valves are specially designed for pre-insulation and buried applications.
  • Hot tapping ball valves are designed for branching existing pipelines under pressure.
  • Butterfly valves are designed for District Heating (CHP) installations, Heat Transfer piping, oil lines and oxygen-free water lines.
  • Control ball valves are designed for control of liquid flows in heating, cooling and air-conditioning systems. Naval Control valves can also be used as shut-off valves.
