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 does the gate valve SZ45X-1.0 stand for?
A modelModel SZ45T-1.0, especially in DN100 ~ DN300 piping, soft sealing gate valve shall be used
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 is the difference between the cut-off valve and the gate valve?
Selection of stop valve:There are two ways to install the valve, one is the media flow from the top of the spool, the advantage is that when the packing is not under pressure, the pressure can be replaced before the valve packing, there is a long service life characteristics. Another is the media from the bottom of the spool into, and its shortcomings are driving torque is large, is 1 times above the flow, the stem by the axial force of large, easy to bend the stem. Generally suitable for small caliber manual stop valve, to stop 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.Selection of gate valve and stop valve:Valve than the valve structure is simple, better sealing, manufacturing and maintenance to be convenient; shortcomings are fluid resistance, power, and opening and closing efforts. Gate valve, stop valve are fully open, fully closed valve, suitable for making cut off, it is not suitable for use as regulating valve. The application process should pay attention to the characteristics of the valve when selecting. Small pipes and better sealing performance generally use cut-off valve; in the steam system and large diameter pipeline, due to fluid resistance is small, suitable for use gate valve.
Q:What is gate valve (with force transfer joint)?
Flange valve is equipped with a force expansion joints, easy installation
Q:What type of flange does it fit with the gate valve?
This depends on the type of gate valve, valve standards are marked with matching flange standards. Different types of flanges for different gate valves are also different.The flange of General GB gate valve is GB/T9113 series.
Q:What is the difference between gate valve Z41T and Z45T?
The difference between Z41T and Z45T is that 41 is the dark rod, that is, the screw is not out of the turbine, and the 45 is the Ming bar, the screw out of the turbine outside, the price is also different?.
Q:Why the valve can only be fully open and fully closed valve can adjust the flow?
Valve, if adjusted, it is easy to wash the sealing surface, resulting in sealing surface damage.
Q:Why does the fire hydrant box in the air defense area need to be added with gate valves?
3, protective valve should be used for stainless steel or copper gate valve or cut-off valve;4, air defense enclosure structure, the distance from the proximal end of the valve should not be greater than 200mm. Valve should have obvious signs of opening and closing.
Q:What is gate well?
Gate valve well: it is a irrigation network system which aims at improving water utilization and efficiency, aiming at the construction of water saving and high-efficiency agriculture as well as scientific and technological innovation as well as convenient operation and management.
