Check Valves
Check Valves are used in pipes under pressure between Class 150~2500LB, working temperatures﹣196~600℃. They are used in industries including oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.
Design Feature of Check Valves
1. The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2. Either soft or hard seal can be selected for the product upon different working conditions. The sealing face is built up with Co-based carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
3. Small opening pressure, the disc can be opened fully with a very small pressure differential.
4. Inside-set bolt-bearing structure reduces leakage and reliable use.
5. Class≥1500LB, the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure the sealing performance.
6. Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirement

- Q:What is the check valve?
- Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.Check valve (Check Valve): divided by the structure, can be divided into lift check valve, swing check valve and butterfly check valve three. Lift check valve can be divided into vertical and straight through two. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check butterfly butterfly, double butterfly, butterfly single, more than a few kinds of check valve, in connection form can be divided into thread connection, flange connection, welding and clamp type connection four kinds.
- Q:How to control the common flue return and smoke return?
- In the decoration practice, in order to smoke more smoothly, often install lampblack machine, workers will tear down the developer of the check valve. Even then, there will be no recharge.If you check the check valve is no problem, then only the design of the flue, the smoke does not flow smoothly to the outlet. It is not the problem of lampblack machine.
- Q:What is the function of the ventilator's check valve?
- The utility model relates to a flue check valve, which belongs to an automatic valve, and the main function of the utility model is to prevent the backflow of oil smoke, and only to flow in one direction, and to block gasFlow in reverse direction. When the soot exhauster starts to work, the air flow with the oil smoke pushes the one-way smoke valve through the air inlet and the flow guiding curved surface, and the soot is discharged into the public smokeWhen the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.
- Q:Does the tap water return to the water?
- The tap water check valve will not be discharged without water
- Q:Check valve does not automatically check back, how to adjust?
- 4 the vertical lift check valve shall be mounted on a vertical pipe.5, the lift type horizontal check valve shall be installed on the horizontal pipe.6. Do not check the weight of the valve in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system.
- Q:Can the check valve be used on the steam pipe?
- The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
- Q:Is the check valve the same?
- Same。 Call a difference; a thing. You come to our store to have a look.
- Q:Installation position of air pipe check valve
- If you are not in a hurry, leaving QQ, etc. I reply to your husband for this afternoon, he is very professional.
- 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:I also calculate each pump check valve and gate valve?
- The pump adapter itself does not include the gate valve and the check valve! Only when a group called pump adapter will include adapter, gate valve and check valve!If the pump adapter in the list of units for the group then all included and work content in clear note on the contents.If you do it alone, write out no items!
