Product Details

Product Description:

The JIS Dual Plate Wafer Check Valve is used for pure pipelines and industrial, environmental, water treatment, high-rise building water supply and drainage pipelines to prevent reverse flow of media. The check valve adopts a clip type, the butterfly plate has two semicircles, and the spring is forcibly reset, and the sealing surface can be a body wear welding wear material or a lining rubber, and the utility model has wide application range and reliable sealing.

Applicable medium:

Fresh water, sea water, air, steam, food, medicine, and various oils, acids, alkalis, salts, etc.

Features:

Long service life, reliable sealing and no need for frequent maintenance. The flow characteristics of the butterfly valve are three times that of the shut-off valve, which is 75% of the gate valve of the same specification. The butterfly valve can realize the switching and regulating function of the fluid in the pipeline, and has a better multifunctional type than the gate valve and the shut-off valve. The choice of inner parts and elastic attack materials is a wide application of butterfly valves in the chemical industry.

The butterfly valve is light in weight and small in size. For example, the weight and volume of a 10" butterfly valve are 1/9 and 1/6 of a 10" gate valve, respectively. Therefore, the butterfly valve is easy to install and saves the cost of the piping system. Compared to metal-sealed gate and globe valves, a soft-sealed butterfly valve provides complete airtightness. The butterfly valve is easy to operate and can be opened and closed in the 90° range. The price of the butterfly valve of the same specification is about 35-40% of the price of the gate valve, and the installation cost of the butterfly valve is also relatively low. The correctly installed butterfly valve has a certain self-cleaning property and is not easily damaged by the dirt in the pipe.
