Q: What are the advantages and disadvantages of flat gate valves?: The advantage of flat gate valve is that the flow resistance is small, and the flow resistance is similar to the flow resistance of short valve. The flat gate valve with guide hole is installed on the pipeline and can be directly cleaned with the cleaner. As the gate is sliding on the two seat surface, the flat gate valve can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually positioned automatically. The seat seal surface is not subject to thermal deformation of the valve body. Moreover, even if the valve is closed in cold condition, the thermal elongation of the stem will not cause the seal to be subjected to overload. The length of the structure is much shorter than that of the ball valve, and it is easier to start. Light plate gate valve is more refined, but the effect is exactly the same.The disadvantage of flat gate valve is that when the medium pressure is low, the sealing force of the metal sealing surface is insufficient, so as to achieve satisfactory sealing. On the contrary, when the medium pressure is high, if the sealing surface is not lubricated by the system media or foreign media, often opening and closing may cause the sealing surface to wear too much. Another disadvantage is that the circular motion of the circular gate in the circular flow, only when it is at the valve closed position of 50%, this valve is more sensitive to flow control. Moreover, the gate will produce severe vibration when it breaks the high-speed and dense medium flow. The valve seat can also be throttled if the seat is made of a V - shaped opening and is tightly oriented to the gate.

Q: What are the working principles of the electric gate valve?: You see what type of electric valve, is integral or ordinary type, if the overall type Denso took power on the line, is generally 380V and 220V power supply, and then according to their own needs and then open the signal line, in place and closing in place and remote control line, valve position feedback signal 4~20ma over torque protection, fault signal. 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: 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: 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: The difference and use of gate valve and stop valve: Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.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 many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.

Q: What does the gate valve 150# mean? Is it stress PN? What's that, PN16 or?It's better to have some specific links, thanks!: I think PSI is equal to 150#The sign behind is "PSI"You Baidu "ANSI standard pressure, pound scale and nominal pressure relations table" will knowI'm new, too, I understand

Q: What is an inverted seal gate valve?: When the inverted sealing gate valve is fully opened, the sealing of the sealing is brought together, and the sealing effect is reduced, and the erosion of the filling to the fluid is reduced, and the service life of the filler is prolonged, and the possibility of leakage is reduced. Generally on the gate valve, stop valve has inverted sealing requirements.

Q: What does gate valve DN80-PN16-QT450 mean?: DN80 means that the nominal diameter of the gate valve is 80mm, and PN16 is the nominal pressure of the gate valve is 16Mpa. Q quick form T cast iron, 450 flanged connection single gate valve.

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: Fire protection gate valve from the wall how many distance there is no regulation?: 1 meters away from the wall, leaving the maintenance and replacement distance
