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: 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: Check valve h42h-dn80 what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:H = check valve4 = connection: flange2 = structure form: vertical lifting typeH = sealing surface material: Cr13 stainless steelDN80== nominal diameter: 80mm

Q: What are the differences between different check valves applications? For example, is the fire pump outlet swing check valve or a silent check valve? According to 35How to recognize single wall corrugated pipe and double wall corrugated pipe? Which is better?.What's the use of the silent check valve? And the bellow problem below, is there no answer?: The application performance of the acoustic check valve only allows the medium to flow in one direction, and prevents flow in the direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow. Not suitable for medium containing solid particles and viscosity. The design of the check valve takes full account of the requirements of the use of the environment, and uses the inclined plate structure to achieve no vibration, no noise, stable operation, and ensure the quiet environment of the hotel and the residential environment, and has the effect of energy saving.

Q: What does the number 16 on the check valve mean?: This is the pressure level of the valve, which represents 16Kg, which is used for piping pressure less than this pressure.

Q: What are the differences between the vertical check valve and the horizontal check valve?: The structure principle is the same, but the cost and volume are different, there is nominal pressure difference, the use place is different

Q: How to use the check valve when the size of the pressure?: When using check valves, the magnitude of the pressure shall correspond to the pressure level of the pipe

Q: The difference between slow closed valve and open the valve: The difference is mainly that the opening and closing of the slow closing check valve depend on the external and external forces to perform the slow opening and closing (usually hydraulic cylinder or pneumatic cylinder). The swing check valve is opened and closed by the pressure of the pipe medium to complete the opening and closing (and the pressure of the pipeline).

Q: How do I install the pump outlet check valve?: Because the check valve is easy to be damaged, therefore, the check valve shall be installed near the pump outlet, and a shut-off valve (usually ball valve or gate valve) is arranged on the top of the check valve, so that it is easy to overhaul. In order to facilitate the check valve before disassembly pressure relief, the valve itself is not equipped with a net valve, should be installed between the check valve and the shut-off valve with pressure relief valve.

Q: See English design drawings, found the check valve to a lot of good variety, do not know how to translate, please come and see God, and generous with your criticism.CHECK VALVE I search on the Internet, that is, the meaning of the check valve, but so many kinds, really do not know what it means, not only did not see, never heard of.CHECK VALVE - ANGLECHECK VALVE - ANGLE STOPCHECK VALVE - ANTI WHIPCHECK VALVE - STOPCHECK VALVECHECK VALVE - TILTING DISKCHECK VALVE - WAFERCHECK VALVE - Y STOPHigh reward oh, good answer, I will give you a big additional scores drop, huh, worried about kazakhstan. StopPlease make a explanation according to my offer English name, online copy paste do not explain visual satisfaction, I will give you an additional 20~100.Starbooks | browse 5128: 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.Structure check valve (One-way valve): divided by structure, can be divided into lift check valve, swing check valve and butterfly check valve three. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three.Install vacuum check valve (One-way valve): should be installed in the top note of the following things: 1, the pipeline will not bear the weight of the check valve, large check valve (aetv One-way valve): should be independent of support, so that the pressure piping system from the.2, installation, pay attention to medium flow direction should be consistent with the body of the arrow direction.

Q: What is the difference between globe and check valves?: 1. check valve is called one-way valve, the role is to prevent fluid flow, can not be adjusted, can not be closed.2., the cut-off valve can be used to regulate flow, can be closed, can be closed.
