JIS F7312 C.S. Angle 5K

Fluid Condition Oil and pulsation water	Maximum Working Pressure MPa [kgf/cm²]
Fluid Condition Oil and pulsation water	0.49
Non-shock water of 120ºC or less	0.69

JIS F7320 C.S. Angle 10K (16K)

Fluid Condition Steam of 300ºC	Maximum Working Pressure MPa [kgf/cm²]
Fluid Condition Steam of 300ºC	0.98
Steam of 220ºC or less	1.18
Air, gas, Oil and pulsation water	1.18
Non-shock water of 120ºC or less	1.37

JIS F7314 C.S. Angle 20K

Fluid Condition Steam of 400ºC	Maximum Working Pressure MPa [kgf/cm²]
Fluid Condition Steam of 400ºC	2.26
Steam of 350ºC	2.55
Steam of 300ºC	2.84
Steam of 220ºC or less	3.04
Air, gas, Oil and pulsation water	3.04
Non-shock water of 120ºC or less	3.33

3. Construction, Shape and Dimensions
　　The construction, shape and dimensions shall be as shown in the following tables. The permissible deviation of body thickness "a" shall, as a rule, be within +15~-10%, but when the calculated value is below 1 mm, the deviation may be permitted up to 1 mm.

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

The angle valves shall be tested as followis:

   JIS F7312 C.S. Angle 5K
     （a）Watertight inspection for valve seats: 0.76 MPa[7.7 kgf/cm²]
     （b）Hydraulic inspection for body: 1.04 MPa[10.5 kgf/cm ²]

   JIS F7320 C.S. Angle 10K
     （a）Watertight inspection for valve seats: 1.51 MPa[15.4 kgf/cm²]
     （b）Hydraulic inspection for body: 1.04 MPa[10.5 kgf/cm ²]

   JIS F7320 C.S. Angle 16K
     （a）Watertight inspection for valve seats: 3.67 MPa[37.4 kgf/cm²]
     （b）Hydraulic inspection for body: 5.00 MPa[51 kgf/cm ²]
