H41Y forged steel flange check valve Product Description:

Forged steel flange check valve disc and seat sealing surface using cobalt-based carbide plasma spray welding hardness, erosion resistance, durability. Apply to the operating temperature of 600 ℃ petroleum, chemical, hydraulic, thermal power plants and other conditions of the pipeline cut off or connected to the media. Suitable media: water, oil, steam, and gas, some corrosive liquids.

H41Y forged steel flange check valve How it works:

Forged steel flange check valve disc, valve seat sealing surface using iron-based alloy or stellite (Stellite) Cobalt-based hard alloy welding surface into a wear-resistant, high temperature, corrosion resistance, abrasion resistance and good service life Long and so on. Stainless steel pin and valve flap with built-in structure - excellent performance - more reliable sealing. Products are widely used in petroleum, chemical, pharmaceutical, power industry and other conditions of pipeline anti-media backflow effect. Suitable medium for water, oil, steam, gas and some corrosive liquid media.

H41Y forged steel flange check valve Features:

1, the guide ribs on the hard alloy surfacing alloy sleeve made of stainless steel guide to ensure flexible action.

2, the valve disc and seat sealing surface made of cobalt-based carbide plasma spray hardness, erosion resistance, durable.

3, advanced pressure seal design and high purity graphite gasket ring to ensure high air tightness.

4, the valve cavity with self-tight pressure seal structure, the higher the pressure within the cavity sealing performance.

5, the valve flap around the valve seat outside the rotation, reducing the violent impact occurred when closed.
