Product Details: DN150 ANSI Class 250 Swing Check Valve


Product Usage


Swing check valves are used in pipes under pressures between PN1.6-42.0MPa, working tempertures between -46℃~570℃,they are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power generation to prevent the backflow of the media.


Product 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 used

  4. When pressures≥16.0MPa the valve belly, self-tighening structure offers a tighter sealing for a higher medium pressure;

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