Ductile Iron Check Valve DN1400 Quality Guarantee China

Q:What are the brands of check valves?: Also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.

Q:What are the differences between the vertical check valve and the horizontal check valve?: The main difference is whether the valve center and valve seat are placed horizontally or vertically. It is usually designed with the pipe

Q:Are the common check valves stand upright or horizontally installed?: 1 straight through lift check valve should be installed in horizontal pipe, when the media to stop the flow, the valve by the weight of landing on the seat to prevent the media back; because the vertical lift check valve medium inlet and outlet channel direction and the direction of the valve seat, so it must be installed in a vertical pipe.

Q:The principle of the check valve: The function of the check valve is to allow the medium to flow in one direction only, and to prevent the flow in the opposite direction

Q:How much is the check valve for the concrete pump?: 31 concrete pump price ranging from 15W to 60W, different configurations have different prices, which one do you want?

Q:How does the check valve work?: Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, counter flow valve and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface.

Q:What does the check valve "H44Y-160" mean?: H- check valve, 4 flange connection, 4 spiral structure, Y- sealing surface material is hard alloy. 160 table nominal pressure 16MPa

Q:Is it necessary to install a check valve in front of the water meter? Does the water company have a definite requirement?: UnnecessaryWater meter before the loss of running water, their own things, do not need customers to bearAfter the water meter is equipped with a small gate valve or a ball valve, it is convenient to repair and replace

Q:Are check and check valves the same kind of thing?: The same thing is not the same as it is

Q:Why can't parallel check valve be installed firmly?Anonymous browsing | 51 times: The vertical installation is easy to cause the valve core of the check valve to clamp off or fall off, and lose the function of checking back. The direction of the check valve is restricted seriously from any direction of the medium
