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 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

Q:What are the ten major brands of copper check valves?
I knew that:1, Amico2, Jie Kelong3 crown4, good day5, KITZ
Q:Is the tank stop valve a non-return valve or a check valve?
Check valve is a one-way valve, automatically prevent reverse flow of fluid, no knob, can not be artificial blocking forward flow.
Q:Detailed distinction between backflow preventer and check valve
The backflow preventer consists of two separated check valves and a drain valve. Due to the local head loss of the check valve, the pressure in the middle cavity is always lower than the pressure at the inlet. This pressure difference causes the drain valve to be closed and the pipe is in normal water supply. In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.
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:Which kind of steam check valve is good?
Steam check valve selection spring pressure check valve is better, can be sealed tight.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.
Q:What's the use of the check valve?
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. 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:Are the common check valves stand upright or horizontally installed?
3. install the check valve, pay attention to medium flow direction and check valve arrow direction should be consistent.
Q:Does one-way check valve affect water flow?
The water inlet of the household water heater is equipped with a triangle valve, which will not affect the flow of water, and be convenient for maintenance and inspection
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!
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.
