Specifications

400X Flow control valve
1.Above 25 years professional manufurer
2.CE,WRAS and ISO9001
3.DN32-DN1200

The valve limits the flow rate in the pipeline to a preset rate, regardless of upstream pressure variations. The valve is controlled by pilot valve, which takes use of integrated orifice plate to detect flow rate represented by differential pressure, and the differential pressure is used to control the pilot valve to implement flow rate control.
The 400X flow control valve is a multifunctional valve that adopts the mode of flow control employed by high-precision pilot valve. It is suitable for use in water distribution pipes within which the flow and pressure need to be controlled, and can serve to keep thepreset flow constant, restrict excessive flow at a preset value and reduce the excessively high pressure upstream properly. This valve differs from other conventional throttle valve, which normally work through reducing the flow area bymeans of orifice plates or purely mechanically,by making use of an appropriate pilot valve to minimize the loss of energy in the course of flow regulation. The 400X flow control valve can completely stop the flow in case of an emergency to avoid loss. Accordingly, it boasts high control sensitivity and isreliable, safe,simple to debug and offers a long service life. Pressure Rating: PN10. PN16. PN25/Class150Size Range:
DN20mm-DN800mm (3/4" - 32")Test and inspection: GB/T 13927 API598

Q: Where is the filling portion of the valve?: Along the stem to find, stem into the valve can not see, invisible place, here is the filler. Popular bar!

Q: Where is the Shanghai valve? What brand is good?: To tell the truth, I think the Shanghai Yang Yi valve is good, in product quality, as well as product packaging are very good, especially after sale service, are free of charge

Q: What does "TD671F" mean?: You should type is wrong, or I should be D671F, with very limited knowledge and scanty information, this type of mean (D) pneumatic butterfly valve (6) of the clip (7) sealed the middle (1) fluorine plastic (F). There should also be a number of pressure figures and body material. For example, D671F-10C later means that the pressure is 10 kilograms (or 1.0MPa) and C represents the carbon steel

Q: How can you replace the other valve when the main valve is not closed and no water is stopped?: Not recommended against the flood to repair the valve, first you have to be repaired, second may be more complex, it is not easy. I have a bad experience this, take the valve, because it is plastic, and aging, the thread is broken, the new is not on do not have to flow out of the water, get it is. To find the valve, the mess!

Q: What courses in the University involve valves?: Pressure vessel design, the valve is essentially a pressure to withstand the container. The valve can be understood fundamentally.

Q: 1) the valve plate, valve gate valve, the difference (my personal understanding is that if it is on the ball, called the valve, if the valve is called the gate, is actually a meaning in different valve called, please help me understand it right?)2) valve clack. What's the spool?3) the valve seat is welded inside the valve, or is it directly installed inside without welding?4) when opening the valve, if the valve seat is not welded, then, under the pressure of the medium, why not open the seat?.5) excuse me, pressure self sealing (my personal understanding is that when the valve is closed, the valve plate and valve seat depend on the pressure of the media, and they fit together to seal the effect: The first question is basically the same, and you can understand that for the secondThe 3,4 problem, there are several seat connections, such as thread connection (threaded, the valve seat is connected with the valve), modular connection (such as adding the cage to a fixed seat, the crushed) as one of the body and there is (some welding). The valve seat must be fixed.The fifth question, you are right!

Q: How to check the quality of the valve?: First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level. Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem. Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.

Q: In the decoration, I do not know where to get the valve, what kind of products should be bought?It is hard to fit the valve in the water inlet of the house. If not, can you? Will it have any effect on future use?: All inlet pipes should be fitted with valves, so if the faucet breaks, you'll know the benefits

Q: What's the caliber of the valve 1/4?: DN6Metric corresponding tableDN3 1/8DN4 5/32DN6 1/4DN8 5/16DN10 3/8DN15 1/2''DN20 3/4''DN25 1''DN32 1-1/4''DN40 1-1/2''DN50 2''DN65 2-1/2''DN80 3''DN100 4''DN125 5DN150 6DN200 8DN250 10DN300 12DN400 16DN450 18DN500 20DN600 24

Q: What do O and S mean on the valve?: Generally used in process valves, operating conditions required to open and close, especially in the case of pneumatic actuators installed, the loss of power and gas supply valve when the state
