4.2 Installation of a Valve With Closemount Hardware
If the electric actuator has been specified for use with closemount hardware, it will
be received from the factory with the CR4/clamp ring already affixed to the
actuator. The clamp ring is attached to the actuator with a two HWSC-SC8-
6TDH/modified socket head screws (8-32 x 3/8").
CAUTION: Do not use screws longer than 1/2" to attach clamp rings to
electric actuators. They will interfere with internal moving parts and
damage the actuator.
1. Plug in the electric actuator and put it into the LOAD position (indicated by a
red light in the LOAD position) on the control box. The valve will have been
rotated to the counterclockwise position before the knob or the handle was
removed, so they should now be in the same relative rotational position.
CAUTION: The valve and the actuator must be in corresponding
rotational positions before assembly. If they are not, the valve or
actuator may be damaged when operated.
2. Place the slotted coupling over the driver (Figure 8) or the valve shaft
(Figure 6 and 7) and engage the rotor pin.
3. The actuator is shipped with the CR41/closemount standoff mounted in the
CR4/clamp ring. Remove the CR41 from the CR4 and attach it to the valve
body with the two HWSC-SC6-10NT/modified socket head screws (6-32 x
5/8"). (Only one is used for a P-Type 10 port valve.) The CR41 must be
oriented so that the valve cutout is visible through the long slot on its side.
4. Press the flange of the CR41/closemount standoff into the CR4/clamp ring
on the actuator, making sure that the square driver of the actuator engages
the squared hole of the slotted coupling. (It may be easier to put the slotted
