Warning
1. Avoid using the valves in half opened position.
Since it may result in seat deformation or
leakage.
2. Operate the valves taking up a stable posture
from a set direction, after checking that the
specified handle is fastened by bolts/nuts.
Also, when operating the valve with spare
handle, please make sure that the handle
is reliably inserted into the shaft's end.
Insufficient insertion and forced operation of
the handle may result in damage or injury if
the handle slipps out.
3. Excessive handle operation may break the
lever, injure the operator, and/or deform the
stopper or the shaft, which may also result in
seat leakage.
4. Be careful in handling the valve where high
temperature fluid flows in the pipeline. The
heated valve may cause burn injury of bare
hands.
