High and low pressure relief valves for direct coal liquefaction
Thread Content
The high and low pressure relief valves are severely worn – is there any good solution? Any requirements for the material? Which manufacturer is good to choose? ?
Weren’t the valve core and seat hardened?

Laser cladding of high-hardness alloy materials results in a hardness of 63HRC; compared to methods such as spraying and welding for strengthening, the wear resistance of the strengthened layer increases by more than 3 times at the same thickness.
