Q:What is the difference between Z41X gate valve and Z45X gate valve?

All flange soft sealing gate valve, but 41X is Ming bar, 45X is dark pole

Q:Gate valve Z41H-16Q generally used for what place?

Gate valve is one of the most commonly used cut-off valve, mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Suitable for medium and large diameter pipelines.

Q:How to distinguish between gate valve and cut-off valve?

Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!

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 are the meaning of the cast rigid gate valves z41h-16c?

According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== flange connection1== rigid single gateH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaC== body material: carbon steel

Q:What else, P54140V, 170V? What do they mean?

P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar

Q:What does gate valve Z41H-40 mean?

40 kg flanged cast steel gate valve；Flanged gate valve, 40 pressure

Q:The main question is, what are the functional differences in which case?

The gate (gate valve) is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle gate valve. The direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.Gate valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex

Q:What do you mean by forged steel gate valves 800LB DN20 SW?

Forged steel gate 800LB pressure DN20 is by SW said socketweld (connection)
