1.Lift check valve is self-sealing valve. The disc can be acted by the flow which can protect against the media flow back.

2.The disc with spring can keep the valve work in any direction.

3.Reasonable structure, reliable sealing, excellent performance and attractive appearance make a TKFM valve.

Q:What type of check valve is the h61y-40 check valve?
The disc type check valve is simple in structure and can only be installed on the horizontal pipe. The sealing performance is poor. Five. Check valves: Valves sliding along the centerline of the valve. Pipe type check valve is a new kind of valve. It is of small size, light weight and good processing technology. It is one of the developing directions of check valve. But the coefficient of fluid resistance is slightly larger than that of the swing check valve.
Q:What about boiler non-return valve without return?
There are two reasons: 1 pipe dirty, need to clean up.2 pressure difference between the two sides of the valve, see the pressure on both sides is how much?
Q:How to install the check valve?
Check valve [1] called one-way valve or check valve, its role is to prevent the media back in the pipeline, a swing check valve: Valve swing check valve cylindrical disk-shaped, around the seat of the shaft for rotation channel, because the valve channel into a streamlined, flow valve smaller than the lift check, for large caliber occasions in low flow and no flow frequently changes, but not for the pulsating flow, the sealing performance is less than lift. Swing check valve is divided into single, double, and most types of three, the three forms mainly by the valve bore points, the purpose is to prevent the media to stop flow or reverse flow, weakening the hydraulic impact. Two. Lift check valves: check valves slide along the vertical centerline of the valve body. The lift check valves can only be installed on the horizontal pipe. 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 direction of medium inlet and outlet channel direction perpendicular to the seat; vertical lift check valve, the media import and export channel in the direction of the same direction with the valve seat, the flow resistance is smaller than the straight through.
Q:How do I install the pump outlet check valve?
Order note: 1. Pump outlet check valveProduct name and model number 2. Whether or not to take accessories for our correct selection. Use pressure. Use medium temperature.Two, if the company has been selected by the design unitPump outlet check valve type, please pump outlet check valveThe model is ordered directly from our sales department.Three, when the use of the occasion is very important or the environment is more complex, please try to provide design drawings and detailed parameters, by our valve company experts for your audit checks. If you have any questions: please call us for advice:,We will do our best to provide you with quality service.
Q:What is the function of the check valve on the air compressor?
It can cause damage to the compressor (usually called liquid hammer). Also, the exit may be frosted by returning air.
Q:What is the difference between the H44H check valve and the H41 check valve?
The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system2, attention should be paid to the direction of the flow of the medium should be in accordance with the direction of the body marked arrow3. Vertical lift check valves shall be mounted on vertical pipes4.
Q:The difference between the plunger type check valve and the lift check valve
Standard light valve professionals to answer for you,The plunger type check valve is a variant of a conventional stop valve. In this valve, the disc and valve seat are usually designed on the basis of the plunger principle. The disc is polished into a plug and is connected to the valve stem. The seal is made of two elastic sealing rings attached to the plunger.
Q:Installation of stainless steel tank outlet must be equipped with check valve?
A stainless steel ball valve can also ah, inner thread
Q:Does the tap water return to the water?
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.
Q:Is the check valve the same?
Same。 Call a difference; a thing. You come to our store to have a look.
