Q:Which type of check valve should be selected for vertical pipes?
The check valve on the vertical pipeline shall ensure that the spool goes back to its position when the fluid is stationary and reversed.Optional:Butterfly check valves, pipes of low pressureVertical lift check valve, high pressure resistance, good tightnessSwing check valve: flow must be from the next up, the pipe diameter is unlimited
Q:Are rubber check valves and swing check valves the same type of valves?
Not the same model. The rubber valve check is HC44X, and the swing check valve is H44H
Q:How to install industrial check valves? How should they be used?

Q:What can I do with the lift check 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.
Q:Do you still need to check valve fittings for solar water heater installation?
Need, but now is to switch the valve three, without Duojiabie on it
Q:The difference between the plunger type check valve and the lift check valve
Lift check valve is 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. 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).Hope to be of some help to you!
Q:How much is the 6 point check valve for the water pipe at home?
1, home hose with 6 points of the water pipe, check valve, copper 20-40 yuan.2, check valve refers 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 valve.
