Damaged or worn parts can decrease performance and shorten the life of the overflow trap.
A damaged float ball can result in the inadequate removal of condensate and overflow.
A damaged or worn end cover gasket or inner valve body gasket can cause external leakage resulting in damage
to surrounding equipment and the loss of the steam blanket from the tank.
A damaged float lever can result in the inadequate removal of condensate and overflow or the loss of the steam
blanket from the tank.
A damaged or worn pilot subassembly can result in the inadequate removal of condensate and overflow or the
loss of the steam blanket from the tank.
A damaged or worn piston can result in the inadequate removal of condensate and overflow or the loss of the
steam blanket from the tank and can also cause damage to the valve body.
A damaged or worn inner valve body can result in the inadequate removal of condensate and overflow or the loss
of the steam blanket from the tank and can also cause damage to the piston disc.
A damaged or worn stem guide can result in the inadequate removal of condensate and overflow or the loss of
the steam blanket from the tank and can also cause damage to the pilot assembly.
A damaged or worn clevis, clevis pin, or fulcrum link can result in the inadequate removal of condensate and
overflow or the loss of the steam blanket from the tank.
Three different parts kits are available. The inspection kit allows for the overflow trap to opened so its internal
parts may be inspected. The float ball kit allows for the float ball to be replaced. The internal vba kit allows for the
entire internal valve body assembly, minus the float ball, to be replaced. The internal vba kit is preset at the factory
to provide the correct water level in the float chamber. Please provide serial number to get the correct kit or
individual part numbers.
