Why is my Forbes Marshall Industrial Equipment leaking steam?
If your Forbes Marshall Industrial Equipment is leaking steam, ensure the arrow on the nameplate points downwards during installation. Additionally, inspect the valve and seat assembly for any deposits and clean them. For steam leaking from the trap body, tighten the cover nuts and bolts to the recommended torque. Also, check the gasket for damage and replace if necessary.
What to do if Forbes Marshall Industrial Equipment is not discharging?
If your Forbes Marshall Industrial Equipment is not discharging at all and the surface temperature of the trap is low, first verify the installation, checking the flow direction arrow on the cover and the name plate arrow on the base. Next, inspect the strainer for any blockages. Also, if the actual differential pressure exceeds the design pressure, the steam trap may be closed. Check the valve and seat assembly for blockages. Finally, check if the ball float is punctured; if so, replace it and address any water hammering to prevent recurrence.
How to fix Forbes Marshall SOFT31 Industrial Equipment not discharging enough condensate?
If your Forbes Marshall Industrial Equipment isn't discharging enough condensate, begin by checking the equipment parameters and trap sizing to ensure it matches the recommended size for the condensate load. Also, check for back pressure and corresponding discharge capacities. Leaking traps may increase back pressure, so replace or repair any faulty traps. If multiple traps discharge into a single condensate return line, make sure each has a non-return valve (NRV) on its outlet. Ensure all bypass valves are closed, as leaking or open bypass valves can also increase back pressure.
