DN300-350

Use

Installed in a horizontal pipe, as a safety device to prevent the media from countercurrent.

Structure Description

1.The valve flap moves up and down, and the connecting pipe communicates the upper chamber of the valve with the valve outlet, reduces the shock and vibration when the valve disc rises and falls, and reaches the whole stroke of the valve.

2. The valve body is "Y" type, the resistance is small, the guide ribs on the surfacing iron-based carbide, the valve body guide sleeve made of stainless steel, to ensure that the valve flap flexible.

3. Pressure from the tight seal mechanism, by the pressure of the media itself sealed, the higher the pressure, the better the sealing.

4. Valve and valve seat sealing surface using cobalt-based carbide plasma spray welding, high hardness, erosion resistance, anti-abrasion, durable.
