One-way drain valve product introduction

Unidirectional drainage valve check valve. It is to rely on mediapressure to seal between the valve core and valve, medium pressureis bigger, better sealing performance. The valve cavity at any time canwithstand the pressure line. This valve for the alloy steel forging and become, have strong mechanical properties, can bear high pressure,has safe and reliable performance.

The valve cover and the valve body connected with bolts, the sealingfor the valve cover sealing ring and the inner wall of the valve body,sealing performance and reliable. The assembly clearance it makesthe valve cover and the valve body is very small (design 0), thereby reducing the erosion corrosion medium on the bolt and the screw and reduce the bolt load.

Surface of hard surfacing alloy spool and valve seal, which have good wear resistance and corrosion resistance, the valve core materialadopts anti sulfur steel, other parts of the hardness of the way, so thevalve can be used in the environment with H2S.chinacoal05
