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: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:Is the tank stop valve a non-return valve or a check valve?
- The check valve is not the same as the cut-off valve. The difference between them is mainly that the structure is very different.
- Q:Does the check valve differ in front of the water meter and press it behind the water meter?
- Try to press the front of the water meter, and the distance from the meter is 15 times of the water gauge (15 15*15=225 mm). On the one hand to prevent reflux, on the one hand placed bubble deposition.
- Q:How many kinds of structure are there in the check valve?
- 2. The swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves are generally applicable to medium calibre applications. Large diameter pipeline using single swing check valve, in order to reduce water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a kind of fast developing check valve. Multi valve check valve is suitable for large caliber pipeline;
- Q:Does the check valve of the flue of the range hood work?
- There is also a smoke exhaust smoke fire check valveThe utility model is installed at the rear end of a kitchen fume exhauster or a toilet exhaust fan to a common exhaust pipe inlet with a fireproof grade, and the fan is opened (exhaust gas) when working. In the fan does not work naturally closed (to prevent backflow, waste) or common duct inside temperature reaches a set value can be automatically closed, and within the stipulated period of time to meet the fire performance requirements, the role of smoke from fire retardant valve. This metal valve works on more, the basic effect should be good.
- Q:God, can you explain to me in detail why?
- Check valve in the valve in front. To prevent water from flowing back.
- Q:Today, I saw the name of the fire check valve on the drawing of a project. Who knows what this is? I haven't met before
- The valve of the product is opened, and the direction of opening and opening of the side open type fireproof check valve is consistent with the exhaust direction in the exhaust pipe of the smoke exhauster, and the exhaust is smooth.
- Q:What is the air pipe check valve?
- One-way valve, one-way flow, to prevent negative pressure reflux.
- Q:Does FOTILE hood have check valve?
- If necessary, you can contact the aftermarket directly, technicians can bring home Oh ~!
- Q:What's the difference between the H76H model and the H76J check valve?
- PN1.6-25mpa, 150LB-2500LB, 5K-63K class;6 check valve material: Q ductile iron, C steel, P-304, R-316, A, I titanium alloy chromium molybdenum steel;Check valve common model:Clip on lift check valves: H71X, H71H;Butterfly butterfly check valves: H76X, H76H;Pairs of wafer type check valves: H74H, H74I, H74M;Silent check valve: H42H, H42W;Micro resistance slow closing check valve: HH44H, HH46H, HH49H;Rubber disc check valves: HC44X;Muffler check valve: HC41H, HC41X, HC41T;Lift check valves: H41H, H41W;Swing check valves: H44H, H44W;Chute ball check valve: HQ41X;Welded check valves: H61Y, H62Y, H64Y.
