GB Swing Check Valve
Product overview
Swing check valve 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 backward flux 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 use;
4. Under pressures≥16.0MPa 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 customers' requirements.
