1.  Operation instruction
  valve adjustment is performed through 

lever handle/gear operation. turning the 
shaft clockwise shuts the valve. check the 
operation of the valve by stroking it to ‘fully 
open’ and ‘fully close’. either the hand 
lever or the direction of the parallel flats 
on the top of the shaft indicate the open 
or closed position of the ktM ball valves. 
(see Figure 4) For gear operated valves, the 
position is indicated by the arrow-indicator 
(see Figure 5).

2.  gear operated valve adjustment
  If the gear-operating mechanism indicator 

does not correctly indicate the valve is 
completely open or shut, adjust the opening 
with the adjustment screw. For details, refer 
to emerson sales /service office.

3.  key-lock (option)
  a locking device at the open and shut 

positions can be provided to prevent 
unauthorized or incorrect operation. 
Unlock and detach the padlock otherwise

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.
