Product Details

Product Structure Features

Flanged connection swing check valves(Stainless steel)are used in pipes under pressures between PN1.6~42.0MPa,Class150~2500,working tempertures between -29-570℃, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power generation to prevent the backward flux of the media.


Main structural features:

1. Rational structure, reliable sealing, excellent performance, pretty appearance.

2. Co-radix alloy welded sealing surface, anti-wearing, erosion-proof abrasion-proof and longer use life.

3. Inside-set bolt-bearing structure reduces leakage and reliable use.

4. Under pressures≥16.0MPa, Class1500,the valve belly, self-tightening structure offers a tighter sealing for a higher medium pressure.

5. Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customer' s requirements.
