Q: What exactly is the stem nut, please: Sometimes it is not possible to use copper alloy stem nuts for production and operation. Because some products or environment will corrode copper medium, the material of the stem nut can not be made of copper. On the basis of the electric valve, the stem nut has a melon clutch, which requires a certain amount of heat treatment to achieve more surface hardness and maximum hardness. When using the steel stem nut, we should pay attention to the thread, and the steel stem nut is easy to bite. But the stem nut is only suitable for low pressure and small bore valves. The strength of the stem nut of this material is less than that of the metal stem nut

Q: I have a client in Philippines told me that rival the valve plate and the valve stem is connected by bolts, and our products are connected with a taper pin, please tell me the advantages disadvantages of Comrade conical pin connection and bolt connection. Thank you all: The taper pin is easy to remove and can only be installed in the same direction.

Q: Where is excavator, multiway valve stem processing?: It can be said that the vast majority of the excavator main body assembly are imported, such as Kawasaki Rexroth main valve, main valve, the main valve pike.

Q: If the valve stem in the 50% position of the whole trip, then the flow through the valve is also in the most large 50%?: Not necessarily, depending on the structural characteristics of the valve. In the case of constant pressure difference between the two ends of the valve, if the valve is quick to open, the flow is greater than 50%;

Q: When the valve is installed, should the valve stem be lubricated, or will the material be selected?: Such as for pure water system, do not add, other best add

Q: then stem is how to fit inside the valve body? The outside diameter of the valve stem is larger than the bore diameter: Pass through the runner hole of the valve body and go up

Q: The role of valve stem in process gate valve: Therefore, in selecting the stem material, it must be guaranteed that it is specifiedThe temperature has enough strength, good impact toughness, scratch resistance and corrosion resistance. Valve stem is a vulnerable parts, in the selection of materials should also pay attention to the mechanical processing performance and heat treatment performance, extracted from the www bgfm /, and I hope to help you.

Q: Ball valve stem 90 degrees milling flat, how to process?: Batch processing:1 use special clamps and vertical clamps2 machine tools: horizontal milling machine3 cutter:

Q: I want to start with stem, but I don't know what brand is good, and how big wheels and main lines are used. Ask comrades to introduce.
