Selection Of Material For Boiler Safety Valve


How To Select Valve Materials | Winning Fluid

These materials are much more expensive than common metals, so economy may also be a factor in material selection. Table 2 shows ASTM materials widely used for valve bodies and bonnets. Table 2. But, the majority of valve applications handle relatively non-corrosive fluids at not so high pressures and temperatures to require any exotic material.
