Quick Detail

Wafer dual plate 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 medium. The check valve adopts a clip type, the disc 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.


Characteristics

1. Small size, light weight, compact structure and convenient maintenance

2. The valve plate adopts the dual type, which can be closed by itself under the elastic force of the spring.

3, due to the speed closure, can prevent the media from flowing backwards

4. The valve body structure has small length and good rigidity.

5, safe and convenient, can be used for horizontal and vertical installation


Executive standard

1, flange connection size: EN1092-1/ANSI B16.5/JIS B2220

2. Structure length: API 594, ISO 5752, EN 558.1/JIS B2002
