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 are the structural differences between parallel and wedge valves?

The advantages of dual gate plate is sealed and angle precision low temperature is not easy to make the wedge gate, the abrasion of the sealing surface and shim.The disadvantage is that the structure is complex, easy to stick in the dry medium, mainly the upper and lower baffles. After years of corrosion, the gate is easy to fall off. Although the single gate is sealed and angle accuracy requirements are relatively high, difficult processing and temperature change may make the gate wedge and other shortcomings, but has the advantages of simple structure, reliable use, especially to the flexible gate, can produce the micro elastic deformation to compensate for the deviation between the sealing surface angle processing, which is widely used at present.For more information about valves, please keep an eye on the valve knowledge section.

Q:What do you mean by gate valve type RVHX-0150-10 and Z45X-16Q?

Z45x-16q, Z means gate valve, 4 means flange connection, 5 refers to dark rod gate valve, X means rubber seal, 16 refers to nominal pressure 1.6MpaRVHX means manual gate valve, 150 refers to the caliber of DN150, and 10 indicates nominal pressure of 1.0MPa

Q:What's the difference between a soft seal gate valve and a hard sealed gate valve?

The difference is that the form of the gate seal surface is different.General gate valves are generally leaking, easy to rust and other phenomena. Soft sealing gate valve (elastic seat sealing gate valve), gate material for cast iron lining rubber, overcome the shortcomings of the general gate valve, such as poor sealing, elastic fatigue, easy to rust, etc.. Soft sealing gate valve is a new product of the traditional gate valve.

Q:What is an inverted seal gate valve?

The inverted sealing gate valve is provided with an inverted sealing device, and when the valve is fully opened, an inverted seal is formed, and the filling can be changed under the normal operation of the system.

Q:Is the gate valve clockwise or closed?

In general, the valve is clockwise turn off, in the case of special requirements under the opening.

Q:What is the difference between cut-off valve and gate valve?

Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way
