Q: Soft sealed gate valve and hard sealing gate valve which good?: If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.

Q: Z41T one 10 gate valve and Z44T one, 10 gate valve difference: Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa

Q: What are the main types of gate valves?: sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate valve can be divided into single and dual gate gate plate.

Q: What is the difference between Z41X gate valve and Z45X gate valve?: 2 kinds of valve function, there is no difference.Nothing more than a one with a bright bar. One is a dark pole.Dark pole is cheaper.Everything else is the same. Contact me if you need another valve. Zhejiang Futai Valve Co., ltd.. The contact picture is in the head.

Q: Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?: 3, soft sealing rubber lining valve plate size uniform, interchangeable. Therefore, the soft sealing gate valve will be the direction of development, but also the water supply industry is willing to adopt a valve.

Q: What is an inverted seal gate valve?: It refers to the middle part of the valve sealing valve valve sealing surface, the valve cover has a sealing seat, which is the valve and stem as well as the joint of the valve rod and the valve cover (i.e. internal stuffing box at the bottom of a sealing structure).

Q: What are the differences between the gate valve and the cut-off valve?: 3, 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 a variety of occasions, such as the valve rod the dark bar valve, gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume. Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure and other occasions.4, the cut-off valve is able to stop and adjust the 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 sealing valve has the characteristics of one-way sealing effect, so that the utility model can prevent the working substance from flowing upstream

Q: What are the standards for the execution of cast iron dark pole gate valves?: They are also standard in the production of cast iron dark rod gate valves:Design and manufacture: as per GB/T12234-89 regulationsLength of structure: as specified by GB/T12221-89Flange dimensions: as specified in JB79 GB/T9112-9131Inspection and test: as specified in JB/T9092-99 GB/T13927-92Drive mode: manual, electric, gear drive

Q: Gate valve z41t what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy

Q: The legend of gate valve and stop valve: When the valve is installed, the medium can enter from the bottom of the valve core and enter the two way from the top. Medium from the spool into the advantages of the valve closed when the packing is not under pressure, can extend the service life of the packing, and can be pressure in front of the valve in the case of replacement of packing work. Medium from the spool into the bottom of the shortcomings of the valve driving torque is larger, about 1.05~1.08 times above the entrance, the stem by the axial force of large, easy to bend the stem. To this end, the media from below to enter the way, generally only applicable to small caliber manual stop valve, to the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way. The disadvantage of the medium entering from the top is just the opposite of the way it is entered below.Compared with the gate valve, the utility model has the advantages of simple structure, good sealing performance, and convenient manufacture and maintenance. The disadvantage is that the liquid resistance is large, and the opening and closing force is large. Gate and globe valves are fully open closed type valve, cut off or connected as the medium use, not as a control valve.The range of application of stop valves and gate valves is determined by their characteristics. In the smaller passages, the cut-off valve is used when required for better shutoff; in the steam pipe and the large diameter water supply pipe, the gate valve is generally used because of less fluid resistance.
