Wafer Check Valve

Wafer Check Valve

Check valve is installed on pipelines mainly for preventing the medium from return, being an automatic valve opened and closed by the medium itself.

     CHAODA group专业研制生产Wafer Check Valve等 valve products, CHAODA生产的Wafer Check Valve has the features of Good sealing, reliable, safety and long life span.Class150~Class900,PN10~PN160.  Wafer Check Valve由阀体,阀瓣,阀杆及弹簧等parts组成,采用对夹连接。由于阀瓣的关闭行程短,并且有弹簧加载,可显著减少水锤现象。Wafer Check Valve主要适用于城市,工业及高层建筑给水,排水管网上。由于其Face to face dimensions 比一般Check Valve短,对有安装空间限制的场所最为适用。Wafer Check Valve用于纯净管路及工业,环保,水处理,高层建筑给排水管路,阻止介质逆向流动之用。

CHAODA Valves Group is specialized in manufacturing Wafer Check valve(Ranges from Class150 To Class900, PN10 To PN160) with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. Wafer check valve consists of Valve body, disc, stem, spring and etc with wafer type connection ends. Wafer type check valve could obviously reduce the happening of water hammer with its quick closing together with the structure of spring loaded. As the Face to face dimension of Wafer Check valve is smaller than other types of check valve, it's very suitable to act as the device to prevent the backflow of medium in pipelines served in the Water supply & drainage system of urban, industry and top buildings, environmental protect area, water treatment and etc.

    CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD. is a wholly owned subsidiary of CHAODA VALVES GROUP CO.,LTD.With  Chaoda valves group(简称"CHAODA group") quality management and safety system(Get the approvals of ISO9001,ISO14001,OHSAS18001, API6D, CE/PED, API607,API6FA, ISO15848-1, TS and API600 gate valve certified),top level developing team(Provincial Key Enterprise research Institute,Provincial Key Enterprise Technology  Innovative Group, Provincial Enterprise Technology Center),advanced machining equipment, well chemical analyst and inspection equipment(Optical Spectrometer, Helium low emission tester, High & Low temperature performance equipment and etc)we could provide our clients with perfect products and satisfied service.

Wafer Check Valve product description

    Wafer Check Valve适用于Class150~Class2500,PN20~PN420的各种管路上,用于截断或接通管路中的介质。选用不同的材质,CHAODA group的Wafer Check Valve可分别适用于水,蒸汽,油品,硝酸,醋酸,氧化性介质,尿素等多种介质。

Wafer Check Valves are suitable for using on various kinds of pipeline from Class150 To Class2500, PN20 To PN420 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. 

     Common Problems of Check Valve
        ①密封面破坏;Damage of Sealing face;

        ②杂质附着在Check Valve阀瓣密封面商。修复密封面和清洗杂质,就能防止倒流。The impurity may exist on the sealing face. Clean the sealing face so the check valve could perform well to prevent the backflow of medium.

    选择Check Valve的好处:水锤压力很小,阀瓣行程短,阀瓣轻巧,具有弹簧辅助关闭,关阀速度很快。Face to face dimensions 很短,体积很小,重量很轻,为阀门的安装,搬运,存放及管道的布置带来很大的便利,并能大量节约 material,降低造价。

The advantages of Check valve: Little water hammer effection, short closing to opening stroke, spring loaded disc and quick operation speed. Small face to face dimension, small volume and light weight makes it very easy to install, carry & store the check valve, moreover at the same time reduces the valve's cost.

Wafer Check Valve product features

1.It has short face to face dimensions, only 1/4~1/8 times of traditional flange type check valve.

2.Small volume and light weight, the weight is only 1/4~1/20 of traditional flange type check valve.

3.The disc closes quickly with little water hammer pressure.

4.It is convenient in installation, being available for using on horizontal or vertical pipelines.

5.Smooth flowing passage with small flow resistance.

6.It acts sensitively with good sealing effect.

7.Disc travel is short with less impact force caused by valve closing. 

8.Compact structure and good appearance.

9.Long life span and reliable sealing performance.

Wafer Check valves developed by Chaoda have following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.

     CHAODA VALVES GROUP CO.,LTD. launched its quality management and safety system as ISO9001,ISO14001,OHSAS18001, API6D, CE/PED, API607,API6FA, ISO15848-1 TS and API 600.
