When installing the valve to pipes, do not allow any object, such as chips, to get inside a pipe or valve. Valve cannot fully
closes, or the valve seat may get damaged causing fluid leakage, due to an foreign object jammed inside the valve.
When piping, do not apply too much sealing material, such as solidifying liquid and tape, to the pipe connection sections so
that these materials flow into the valve. Valve cannot fully closes, or the valve seat may get damaged causing fluid leakage,
due to the sealing material jammed inside the valve.
When connecting the valve to pipes, hold the valve body (where a pipe is screwed) with a tool such as a wrench, and screw
the pipe into the valve. (See Fig. 5.) Do not apply excessive torque to the pipe. Refer to the table in Fig. 5 for the
recommended torque.
Figure 5. Valve connection to a pipe
Before activating the ACTIVAL (valve with actuator), flush the pipes (with the ACTIVAL installed) at the maximum flow rate
to remove all the foreign substances. Fully open (in 100 % position) the ACTIVAL to flush.

Identification of the ports A and B
Valve body without heat insulation material wrapped:
Identify the ports with the letters ‘A’ and ‘B’ embossed on the valve body.
Valve body with the insulation material wrapped:
Identify the ports with the tip of the valve joint surface, as shown in Fig. 7.
The port on the side where the tip points is the port B.

Heat insulation
Do not apply heat insulation to the joint surface. Correctly apply heat insulation to the valve as shown in Fig. 8.
