CHECK VALVE WAFER TYPE DUCTILC IRON DN40-DN2000

Q: Does the check valve differ in front of the water meter and press it behind the water meter?: According to the specification, check valve (check valve) should be installed behind the watch. If it is placed in front of the meter, it will cause the meter to be inaccurate and damage the meter parts.

Q: God, can you explain to me in detail why?: Check valve in the valve in front. To prevent water from flowing back.

Q: Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?: If it is water medium butterfly valve, in fact, the same, are used to prevent the media back of the valve, on the models are manufacturers themselves, there is no uniform standard, but only in the use of media on the difference.Butterfly buffer check valve is to rely on the flow of the media itself and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, counter flow valve, and back pressure valveMicro resistance slow closing check valve, also known as check valve, its role is to prevent the medium back flow in the pipeline.

Q: What does the number 16 on the check valve mean?: This is the pressure level of the valve, which represents 16Kg, which is used for piping pressure less than this pressure.

Q: Is the hdf41x 1.6Mpa a check valve?: Backflow prevention device according to tap water supply equipment, especially drinking water pipe back to serious pollution, and effectively prevent the pollution device under the condition of a strictly limited hydraulic control assembly pipeline water only one-way flow of development, its function is to prevent backflow pipeline media in any condition, in order to avoid the purpose of backflow pollution.

Q: What's the difference between the cut-off, check, check, and stop valves three? Better picture,: Stop check valve: when the handwheel is rotated so that the valve stem rises, the disc does not rise together, but only the valve clack is released.

Q: Does the check valve damage affect the flow rate?: Ball check valve will not affect the flow, such as the clip type check valve once damaged, it will affect the flow.

Q: What are the specifications of the DN200 check valve?: DN200, this is the standard! "DN" means the caliber?!

Q: What is the reason that the check valve does not stop water?: 7, when installing check valve, should pay special attention to medium flow direction, should make medium normal flow direction and the direction of the arrow on the valve body is consistent, otherwise it will cut off the normal flow of media. Valve should be installed at the bottom of the pump suction pipe.The general formula 8, lift check valve should be installed in horizontal pipe, vertical lift check valve and bottom valve is usually installed in a vertical pipe on the road, and the bottom-up flow of media.9, the check valve closes, will produce water hammer in pipeline pressure, will lead to serious damage to the valve and piping or equipment, especially for the big pipe or high pressure pipeline, it should pay attention to those who use check valve.

Q: Does the Vatti range hood e601a2z have check valves?: As long as the regular manufacturers of smoke machines must be equipped with check valves, Vatti as a well-known brand of kitchen electricity, this should not worry about you
