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: To prevent water meter rotation, where should the check valve be installed?: Do not pack more than 35 of the weak currentChasing the answerShould be installed at the outlet of the water meter (that is, water to the other side of the room)

Q: Does the check valve differ in front of the water meter and press it behind the water meter?: The combination of the meter and check valve must be the check valve behind the meter because the purpose of the check valve is to prevent the water meter from reversing and to protect the rotating vulnerable parts in the water meter.. At present, there are water meters with check valves, which can simplify installation and provide efficiency

Q: In the water supply system, water pump and water pump without check valve, a water output to another without pump water pump, effect of rotation, it will cause what kind of damage to the pump?: For the work of the pump, when stopped, the water will reverse the impact of the blade, resulting in changes in motor power, while the impact will bring air, it is easy to blade cavitation, affecting the life of the pump ah!Like you said, if the two pumps are connected in parallel, another pump reverses, and that's the same thing. Damage doubles. For a high power motor, it doesn't start several times.

Q: Only one is a soft seal and one is hard sealed: Not the same model. The rubber valve check is HC44X, and the swing check valve is H44H

Q: What is the function of the check valve installed in the water meter before entering the residential water?: Preventing water backflow is also considered from the point of view of water safety.

Q: What are the types of check valves?: Taiwan reasonable, this may not have domestic, if you can name, you can call three one-way valve, we can see in accordance with the structure of the spring type.Front Ze valve provides: hope to adopt!!!I hope I can help you.

Q: What does the check valve h44t-16 mean?: Flanged swing check valve [H stands for check valve, 4 represents flange, 4 represents structural form (swing type), T represents internal copper alloy, and 16 represents pressure 16 pressure. I hope it will help you

Q: What is the difference between the H44H check valve and the H41 check valve?: Swing check valve H44HLift check valve H41HThe installation of check valves (Check, Valve) shall pay attention to the following items1. Do not allow the check valve to bear weight in the line.

Q: How to install the kitchen flue check valve?: To see what the pipeline, the installation of the location of pipe drilling (Professional) wall pipe, according to the back valve installation size, with percussion drilling, with expansion bolts fixed. The calcium carbonate pipeline is directly fixed with screws (hardness is better)

Q: Is it necessary to install a check valve in the piston refrigeration compressor?: The small refrigeration system does not require the installation of a special check valve or check valve.Only the larger refrigeration system needs in the pipeline are arranged on the corresponding one-way valve or check valve when using the piston compressor, the main purpose is to prevent too much liquid refrigerant migration to the piston compressor resulting in frozen oil is liquid refrigerant dilution and lubrication performance variation, the compressor with varying degrees of lack of oil operation.
