1. Scope
  This Japanese Industrial Standard specifies marine cast iron 5K、10K and 16K gate valves, used for steam, fuel oil, crude oil lubricating oil,
fresh water, feed water etc. lines in ships.

2. Relation between Fluid Condition and Maximum Working Pressure

  The relation between fluid condition and maximum working pressure for 16K gate valves shall be 1.57 MPa [16 kgf/cm²] to oil and pulsation
water.

3. Construction, Shape and Dimensions
  The construction, shape and dimensions of the gate valve shall be as shown in the front tables. And the body, bonnet and disc shall be properly
ribbed where necessary. The permissible deviation of body thickness "a" and bonnet "a1" shall, as a rule, be within +15~-10%, but for 5K and
10K gate when the calculated value is below 1 mm, the deviation may be permitted up to 1 mm.
  For the nominal diameter 450 to 600 and working pressure of 0.2 MPa [2 kgf/cm²] or less of 5K gate, the thrust ball bearing may be replaced by
the directly turning type with hand wheel, when specified by purchaser.

4. Test and Inspection
  The gate valves shall be subjected to the following items (1) to(5) of inspection in accordance with JIS F7400.
  (1)Material inspection
  (2)Visual inspection
  (3)Dimensional inspection
  (4)Assembly inspection
  (5) Hydraulic inspection

  The gate valves shall be tested as given in the following tables. However, watertight inspection for valve seats of valves with nominal diameter
300 or more may be performed with lower pressures specified by purchasers, than the test pressure specified in the following tables.
