Retrofitting and adjusting a stroke

the risk of burns.
Wear protective gear that is suitable
for the temperatures generated in your
plant.

You can retrofit a stroke limiter.
The optional stroke limiter limits the stroke length, i.
e. the max. opening of the valve. Consequently, you
can limit the flowrate.
A commercial-grade hexagon bolt with nut serves
as stroke limiter. The size of the hexagon bolt and
nut depends on the equipment type.
The required hexagon bolt and nut are
commercially available.

Procure a hexagon bolt and nut suitable for your
equipment type.
To fit the stroke limiter proceed as follows:
Screw the nut (16) onto the hexagon bolt (15).
Take the sealing plug (14) out of the handwheel
