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 Valve
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

The package of Check Valve
- Q:Can the swing check valve stand upright?
- Ordinary lift check valves shall not be erected. Lift check valves with springs can also be mounted.
- Q:What is the function of the stop valve and check valve installed on the water supply pipe?
- 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 is the difference in price between the check valve HH48X-10C and the HH49X-10C?
- Since this model has exceeded the standard requirements, so there is no uniform manufacturers. There are dozen HH49X, there are also playing HH48X, HH49X, in fact, are the same kind of valve.
- Q:What does the H/F/P stand for in the check valve H41H/H41F/H41P?
- Respectively, the valve seat sealing surface is made of alloy / fluorine plastic / stainless steel.
- Q:Do you still need to check valve fittings for solar water heater installation?
- Need, the solenoid valve automatically control itself has the function of manual water valve was the installation of the installation, but now a lot of pressure to see you still go not installed, they save cost, but will give users the trouble
- Q:I also calculate each pump check valve and gate valve?
- Should not be installed, if the installation is repeated, in fact, the original design has satisfied these functions! Gate valve is not necessarily a good thing! Nothing is better than fine! Make good use of the gate valve!
- Q:My hood inside outside blow valve pops ringing
- Do you think the situation in the wind ` a valve installed in the opposite direction of the flue you can, you should pay attention to when installing wind don't understand the whole, an anti air valve system, like on the wall in the general store has large lampblack machine. Or you in the hood where to buy, you can go to a can go, I also bought the lampblack machine, where he will give you, or call at the time according to the hood people to give you what you can handle.
- Q:What are the main types of check valves?
- Two, noun explanation: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.
- Q:Why can't the check valve on the air pipe be used when the wind speed is less than 8 meters?
- First of all, you must understand the working principle of the check valve, indeed, as you said, you can adjust the position of the hammer by adjusting the position of the drop hammer.If you are in their own design and production, consider the thickness of the blade, drop hammer size, weight, and other parameters considered.Hope to be of help to you!
- Q:The self-priming pump with check valve (check valve, water valve)?
- Both, but there are good or bad points, good seal, with a spring, the general is a piece of rubber plus a piece of iron, plus a check valve is feasible
