H67YY Type Special Check Valve

The H67YY type special check valve designed by Dazhong Valve Group is installed on the horizontal pipeline as a safety device to automatically prevent the backflow of the medium. For the lifting movement, the connecting pipe connects the upper cavity of the valve disc with the valve outlet, the valve body is "Y" type, and the resistance is small. Iron-based cemented carbide is surfacing on the guide ribs, the guide sleeve of the upper cavity of the valve body is made of stainless steel, and the valve disc and valve seat sealing surface are made of cobalt-based cemented carbide plasma spray welding.

• Installed on horizontal pipes as a safety device to automatically prevent backflow of media

• The valve flap moves up and down, and the connecting pipe connects the upper chamber of the valve flap with the valve outlet. When the valve flap rises and falls, the impact and vibration are reduced, and the valve flap reaches the full stroke

• The valve body is "Y" type, with low resistance. Iron-based carbide is surfacing on the guide ribs, and the guide sleeve of the upper cavity of the valve body is made of stainless steel to ensure the flexible action of the valve disc

• Pressure self-tightening sealing mechanism, relying on the pressure of the medium itself to seal, the higher the pressure, the better the sealing performance

• The valve disc and valve seat sealing surface are made of cobalt-based cemented carbide plasma spray welding, with high hardness, erosion resistance, abrasion resistance, and durability
