Valve Marking and Identification Paint
This standard applies to valves in industrial pipelines and equipment. 1. Marking content:
(1) Nominal pressure (or working pressure), (2) Nominal diameter:
(3) Arrow of medium flow direction
(4) Factory name or factory logo of the manufacturer
JB 106-78
Replacement JB106-59
(5) Other marks: such as special valves or standard numbers, drawing numbers, special material grades, melting furnace numbers, etc. according to user requirements.
2. Marking method:
(1) Casting method
(2) Stamping method.
3. Marking position,
(1) Nominal pressure (or working pressure), nominal diameter and arrow should be marked on the front of the vertical center line of the valve body in the combination style specified in Table 1. Table 1
Direction of medium flow
The flow direction of medium inlet and outlet is on the same or parallel center line

Use nominal pressure to mark the style
The medium flows upward from the bottom of the valve disc
The medium inlet and outlet flow in a 90° angle
Angle style
The medium flows downward from the top of the valve group
The medium flows from the inlet to the two outlets at the same time to form a "T" shape

Note: ① Valves where the medium can flow in any direction do not need to be marked with arrows (such as gate valves, ball valves, plug valves, etc.). ② The square end face of the ball valve, butterfly valve stem and plug valve plug should have an indicator line to indicate the channel position. ③ The nominal diameter is below the arrow in the style. (2) The manufacturer's name or factory logo should be marked in a place that is easy to see, such as the valve body, valve cover (bracket), handle, wrench, handwheel spoke and other parts. (3) Other marks shall be marked on the back of the valve body or other locations. JB106-78
