3. Construction, Shape and Dimensions
The construction, shape and dimensions of the gate valve shall be as shown in the following table. And the body, bonnet and disc shall be properly ribbed where necessary. The permissible deviation of body thickness and bonnet 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 1mm.

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