Cast Iron Angle SDNR Valve JIS 16K F7378

The JIS F7378 is an angle pattern cast iron SDNR (screw-down non-return) valve for marine piping systems with JIS 16K flanged connections. Product classification: angle SDNR valve with non-return function, type F7378.

Operation

The valve changes flow direction by 90°. The handwheel actuates a disc that seats mechanically for isolation. When open, the disc acts as a non-return element, restricting backflow. Standard JIS F7378:1996 covers cast iron 16K screw-down check angle valves for shipbuilding and marine applications.

Technical Specifications

  • Type: angle globe valve, SDNR
  • Connection: flanges JIS B2220 16K
  • Design/inspection standard: JIS F7400
  • Typical size range: DN50–DN200
  • Body: cast iron FC20 / FC200
  • Seat/disc: bronze BC6
  • Stem: brass C3771BD
  • Stem sealing: packing gland
  • Operation: handwheel, rising stem

Test Pressure

F7378 series: hydrostatic shell test 3.2 MPa, seat test 2.38 MPa for DN50–DN200. Final values must be confirmed by manufacturer’s test certificate.

Suitable Media

Applicable for fresh water, seawater, air, inert gases, steam, and oil, provided temperature, corrosion, and trim selection comply with project specifications.

Selection vs F7377 and F7376

F7378 is selected over F7377 when an angle pattern and flow direction change are required. Use instead of F7376 for JIS 16K lines (not JIS 10K). Not intended for precision control; primary use is isolation and non-return.

Maintenance

Inspect stem packing, seat/disc condition, free movement of the non-return disc, and body corrosion, especially in seawater or steam thermal cycling.
