Ball Valve Mounting Installation Mx4D-xxxx-xxx Actuators on 1/2" to 3" Schneider Electric

DuraLynx Ball Valves

Install the actuator onto the ball valve according to Figure-16.

Note: If space constraints do not allow the actuator to be installed in the standard position,

reposition the mounting plate before mounting the actuator.

The valve should be mounted in a weather-protected area, in a location that is within the

ambient temperature limits of the actuator. The installation of the actuator assembly should

provide clearance on all sides to allow for any maintenance that may be needed (see

Figure-13 thru Figure-15).

1. Follow the general piping practices.

2. Apply pipe sealant sparingly to all but the last two threads of a properly threaded,

reamed, and cleaned pipe. Make sure the pipe chips, scale, etc. do not get into the pipe

since this material may lodge in the valve seat and prevent proper operation of the

valve. The valve must be piped with an inlet and an outlet.

3. Start the joint hand-threading the pipe into the valve. If the thread alignment feels

normal, continue to turn the pipe by hand as far as it will go.

4. Use a pipe wrench to fully tighten the pipe to the valve.

Caution: Do not over-tighten the pipe, which may cause stripped threads. Avoid twisting or

crushing the valve while tightening the pipe.

5. Insulate only the valve body and associated piping. Do not insulate the actuator.

6. In chilled or cold water systems where the environment is humid, use a drip pan under

the valve to catch condensate.

Caution: The Schneider Electric DuraDrive actuator is designed to effectively support its

own weight. No load or weight should be resting on the actuator. Long term damage may

occur to the actuator, mounting connection, or valve.

• Do not insulate the actuator/linkage. Doing so will result in excess heat buildup within

the actuator.

• For non-steam applications the ball valve assembly must be mounted so the actuator

is at least 5q above horizontal (Figure-13) to ensure that any condensate that forms will

not travel into the mounting bracket or actuator.

• On steam applications, the ball valve assembly must be mounted approximately 45q

from horizontal (Figure-14).

• Temperature Restrictions: To maintain the maximum ambient temperature 140 qF (60

qC) of the actuator/valve, the maximum allowable fluid temperature should not exceed

the 250 qF(121 qC) ball valve maximum rating.
