Questions regarding the setting of sampling valves
Thread Content
The regulations state that: \"Generally, needle valves with a diameter of DN10 or DN15 are suitable for sampling valves. For viscous or crystalline materials, sampling valves designed for flushing or three-way plug valves can be used, depending on the properties of those materials.\" ”But these valves are rarely specified in project piping standards; so how do people go about installing them?
A “push-in” sampling valve with a crank can be used.
For special media, you need a complete sampling system, rather than just a few valves
A double-sealed guide rail valve can be used on the pipeline; this valve is equipped with a sampling valve.
Is this type of valve purchased as a special part?
A larger cut-off valve is placed at the front, and special sampling valves are available for viscous or crystalline substances.
Could you explain what kind of special valve this is? Thank you
Generally, it is a 25-ball valve plus a 15-pin valve
