Dustproof sleeve DIN Gate Valve Ductile Iron PN16 / PN10

2. Main feathers of Dustproof sleeve DIN gate valve 


1)Gate Valves :Both design and manufacture are carried out strictly following GB/T 12234, API 600 and API 602. The products feature a reasonable structure, reliable seal, good performance and nice modeling…
2)Compact structure, small bulk, perfect rigidity, safety and reliable.
3)Co hard alloy welded sealing surface, which is wearing resistand, erosion proof, abrasion proof and long-lived..
4)  Manual valve with DN over or equal to NPS10", class 400 pounds and DN over or equal to NPS 6", class 600-2500 pound equip with rolling bearing to operate easily.
5)The structure and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistant..
6) Exchangeable seat, random combine the material of surface of blow down part to meet the requirement of work status, prolong service life.

5.FAQ

1. What's are the characteristics of gate valve?

The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. 

2. What is the work principle of gate valve ?

 The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.

Q:What is the allowable leakage rate of the gate valve D?
In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.
Q:What do you mean by "2" and "200 CF8M"?
CF8M is stainless steel, and 2 is caliber 50200 and should also be bore
Q:What is the meaning of socket welding gate valve A105, D&S:STLT, STEM:13Cr, CL800, SW, AP1602, BB-BG-OS&Y?
Body material: A105Sealing surface material: STLStem material: 13CrPressure rating: CL800Connection: SWImplementation criteria: AP1602BB-BG-OS&Y: plain rod support, bolt connection, flange valve cap.
Q:What's the difference between open rod gate and dark rod gate valve?
4, the dark pole gate valve height smaller size; Ming rod gate valve requires a larger installation space;5, the structure of the rod gate valve is beneficial to the lubrication of the valve stem, and the degree of opening and closing is obvious. The stem thread of the dark rod gate valve is not only unable to lubricate, but also directly accepts the medium erosion and is easy to damage. Therefore, the open bar gate valve is used more widely
Q:About fire valve is gate valve or butterfly valve problems?
Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.
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
Q:What kind of copper gate valve copper content standards, there are no national standards?
Usually copper alloy, rarely used pure copper, there are GB
Q:Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?
the valve before the pressure measuring point, distance of valve straight pipe length is 5 times the diameter of the valve after the pressure valve, the distance is 10 times the diameter of straight pipe length.
Q:What are the working principles of the electric gate valve?
Ordinary type electric valve should be equipped with the control box, the motor is the true story and the inversion, and in general to a trip signal signal is normally open and normally closed, closed in place are normally open and normally closed two points according to their own needs wiring, three lines and then open and close control of the line of control there are also 4 lines to control some manufacturers, as well as the valve position, some three lines connected with the potentiometer, some installed valve position transmitter is connected with two lines, and over torque protection fault signal.
Q:Stainless steel gate valve DN150 200300 weight, who knows?
It depends on different materials and pressure levels. 304 material, high pressure weight will be much heavier.
