INSTALLING A VALVE ON AN ACTUATOR

4.1 Preparing a Manual Valco Valve for Mounting on an Actuator

A manually switched 2 position valve has a handle or knob which must be re-
moved before the valve can be installed on the actuator. Sections 4.11 - 4.14
describe the procedures for various Valco valves.

4.11

Disassembly of a Manual W or UW Type Valve

1.

Rotate the knob counterclockwise so the valve is positioned properly for
later installation on the electric actuator.

2.

See Figure 4. Loosen the set-screw within the W valve knob and pull the
knob off of the manual drive shaft.

3.

Using a 9/64 hex driver, unscrew the two HWSC-SC8-16/socket head
screws (8-32 x 1") until the valve comes loose from the rest of the assembly.
Keep the driver with the valve.

4.

The rest of the assembly will slide easily apart, but you may wish to keep it
together for future use.

5.

Proceed to Section 4.2 for closemount assembly, or Section 4.3 if the valve
will go on a standoff before being installed on the actuator.

4.12

Removing the Handle or Knob from a Valve on a Standoff

1.

Rotate the knob counterclockwise so the valve is positioned properly for
later installation on the electric actuator.

2.

See Figure 5. Simply pull the handle or knob, with the manual handle
adapter and retainer, off of the standoff tube.

3.

Proceed to Section 4.3.
