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 working principle of the flue 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 prevent the airflow from flowing in opposite directions.Simon common flue check valve is the use of aerodynamics and mechanical principles of lever machinery, the use of South Korea's imports of high-quality ABS LG engineering materials for the material.
- Q:Check valve note BC/PISTON: SPR-L what does that mean?
- BC==Bolted Cover/ bolted bonnetPISTON== lifting typeSPR-L==Spring-loaded/ is loaded with springsTogether, it is: a spring-loaded check valve. Bolted bonnet (this is common)
- 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:Check valve can not stop water, how to solve?
- Valve is broken, change one, my family is like this
- Q:Use of fire pump adapter even before you install a check valve
- Multifunctional pump combination device usually comes with safety valves and check valves, usually in the flange pipe interface or who is interface settings simple check valve, safety valve is white, but does not apply to the north, the northern cold, need to separate the pipes below plus a check valve, a higher temperature of the South may be suitable for direct use of non frozen.
- Q:Check valve h44h-25p what does that mean?
- H- stainless steel4- flange connection4- rotary single structure check valveH sealing material is Cr13 stainless steel25- pressure 2.50MPAP-18-8 stainless steelH44h-25p= stainless steel flange connection, swing type single check valve pressure 2.50MPA valve body, material 18-8 stainless steel
- Q:What is the difference between check and check valves? Check and check valves?
- Check valve. Check valve is the same, but the name is not the same. According to the customary name of the country. In fact, the same valve. Are check valvesCheck valves are widely used and there are many kinds of check valves. The following are common water supply and heat check valves:1, spring: the liquid from the bottom up, rely on the pressure spring controlled valve, the pressure disappears, the spring force the valve, sealing liquid backflow. Often used in the smaller diameter check valve.
- Q:Check valve in the water pump when the sound of vibration is very large, what is the matter?
- Called water hammer effect, Baidu search Wikipedia detailed descriptionWater hammer blackout or shut off the valve too fast, because the pressure flow inertia, producing flow shock wave, like a hammer, which is called water hammer shock wave flow capacity pump electric pump and valve failure voltage 1s in the static state to accelerate the flow of the pipeline is zero rated speed rated flow due to fluid volume compression degree the flow changes in pipeline pressure caused by pressure or low impact and cavitation impact force and noise producing hammer like tube called water hammer effect of water hammer effect water pump inertia relationship never mind wall
- Q:What's the difference between a stop valve and a check valve? Is it a valve?
- The cut-off valve is a common valves, mainly used to connect or disconnect the line of medium, generally not for regulating flows.globe valves for a wide range of pressure and temperature, but are generally used for medium and small diameter pipes. The cut-off valve is closed parts (valve) moving along the centerline of the valve seat valve. The stop valve is mainly used for cutting in the pipeline.
- 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.
