Q: The difference between swing check valve and lift check valve: The disc can be used in the high pressure small bore check valve. The valve body of the lift check valve is the same as the cut-off valve (which can be used with the stop valve), so it has a large coefficient of fluid resistance. The structure is similar to the cut-off valve, the valve body and the disc are the same as the cut-off valve. The lower part of the upper valve and the valve cover processing guide sleeve, the valve in the valve lift free guide simple simple light driven, when the medium downstream, the valve thrust open by the media, when the media stopped flow, the valve by the self vertical landing on the seat, preventing the media from the upstream effect. Straight through lift check valve, the direction of the entrance and exit of the medium is perpendicular to the direction of the valve seat. The vertical lift check valve has the same direction as the valve seat and the direction of the inlet and outlet of the valve, and the flow resistance is smaller than that of the straight through valve.

Q: Should the kitchen check be mounted on the wall or on the hood?: It should be mounted on the wall. If you have more questions, click ID.

Q: What are the differences between different check valves applications? For example, is the fire pump outlet swing check valve or a silent check valve?

And the bellow problem below, is there no answer?: General pump station project, for the pump outlet check valve, the following principles should be observed;The outlet check valve shall be used when the diameter of the outlet pipe of the pump is smaller, that is, DN<50mm.The pipeline of the pump outlet pipe diameter DN is larger than 50mm, should be used in swing check valveSwing check valves can be installed horizontally or vertically.

Q: What's the size of the check sleeve?: Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve.

SO just goes back! This valve switch is usually dependent on the medium itself. What about the stop valve?. The flow of water in your pipe is good, I said, stop (if it is an electric globe valve) press the Shimonoseki button. Stop and stop right now. Medium can not flow. I want to open. Press open. The stem is lifted and the medium will flow! Of course inside the internal structure will not give you too much!

Its valve moves up and down along the central line of the channel. The action is reliable, but the resistance of the fluid is large. It is suitable for small caliber occasions. The lift type check valve has an air passage type

Q: See English design drawings, found the check valve to a lot of good variety, do not know how to translate, please come and see God, and generous with your criticism.CHECK VALVE I search on the Internet, that is, the meaning of the check valve, but so many kinds, really do not know what it means, not only did not see, never heard of.CHECK VALVE - ANGLECHECK VALVE - ANGLE STOPCHECK VALVE - ANTI WHIPCHECK VALVE - STOPCHECK VALVECHECK VALVE - TILTING DISKCHECK VALVE - WAFERCHECK VALVE - Y STOPHigh reward oh, good answer, I will give you a big additional scores drop, huh, worried about kazakhstan.
