Q:Valve flange drawing n- up to what

A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size

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

Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. 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:greater than DN50 of the pipeline butterfly valve?

Have not heard of this requirement, before the ball valve and butterfly valve quality is rarely used now are good, can be used, but not easy to control the flow valve butterfly valve can close more time-saving, fluid resistance of small. HVAC branch pipe, to flow control, so the choice of gate valve and cut-off valve is more reasonable, and now choose a ball valve is also a lot.

Q:What is the gate valve for the DN65 hydrant?

DN150, of course. Ask me about fire protection

Q:What are the differences between the gate valve and the cut-off valve?

The operating principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outletAt the same time, usually with the cut-off valve instead of gate valve, but the valve can also be used instead of cut-off valve. Valve sealing performance better, but the size is generally not large, the size of the gate valve can be done great.The main difference between them lies in:1, different structure, gate valve structure is more complex than the height, larger size, from the appearance point of view than the cut-off gate valve is short and high, especially the gate height space needs a higher open bar, the selection in the installation space under the condition of limited attention to.2, sealing surface, valve in the opening and closing valve and the valve seat surface always contact and friction between the sealing surface, and thus easy to wear, especially in close off the valve when the valve before and after the great pressure, sealing surface wear is more serious. And the valve once the valve is in open condition, it's seat and disc sealing surface between, not in contact,

Q:What kind of copper gate valve copper content standards, there are no national standards?

Please refer to: GB/T12225-2005 "general purpose valve, copper alloy casting technical specification" and GB/T 15116-1994 "die casting copper alloy"

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 is the difference between gate valve Z41T and Z45T?

Z41T is a dark pole gate valve, and Z45T is a plain rod gate valve,

Q:Is the gate valve flanged?

The most commonly used gate valves are threaded connections, flanged connections, and welded connections.Like the outer thread connection, the clamp connection, the card sleeve is seldom used.
