Q:What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?

Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel

Q:What's the difference between the knife gate valve and the stop valve?

Minor force needed for opening and closing.Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.

Q:What do you mean by "2" and "200 CF8M"?

CF8M is 316,2 "is 50200 caliber stainless steel pressure (American Standard, LB)

Q:What does gate valve DN80-PN16-QT450 mean?

The outer diameter of the pipe is usually 89mm;"PN16" means the nominal pressure of the gate valve is 16Mpa;QT450 QT said, nodular cast iron, tensile strength is more than 450MPa 450.

Q:What is gate well?

Explanation:Valve wells also called valve wells, underground pipelines and underground pipelines (such as tap water, oil, natural gas pipeline valve etc.) in order to facilitate the opening and closing part of network operation or overhaul when needed, a pit is a similar small room (or well), the valve installation in the pit where, for regular inspection, cleaning and dredging pipeline, to prevent the blockage of the pipeline project. The pit is called a well. There are valves, wells must have valves, but there is not necessarily a valve valve wells.

Q:Which is more expensive, bronze gate valve or brass gate valve?

The advantage of casting method is more obvious. The casting of stainless steel is much more difficult than that of brass.

Q:What does the gate valve SZ45X-1.0 stand for?

A modelModel SZ45T-1.0, especially in DN100 ~ DN300 piping, soft sealing gate valve shall be used

Q:Why the valve can only be fully open and fully closed valve can adjust the flow?

You said the cut-off valve is that the spool is rotating rather than vertical movement structure?Theoretically, the flow regulation can be realized by controlling the position (angle or distance), and all of them have mature products.

Q:What is the difference between a flanged gate valve and a wire gate valve?

Flanged gate valves are flanged and must be welded to the flanges of the pipe, bolted together

Q:What are the main types of gate valves?

According to the different materials for carbon steel valves, forged steel valves, stainless steel valves, cast steel valve, iron gate, ceramic valve;
