applications the valve cannot be mounted vertically and if mounted horizontally the valve
must be 0° to 45° off center of the pipe. Do not install with actuator below pipe.

Instruction Manual
2. If a replacement, remove existing valve, linkage and actuator from the
piping system.
3. If actuator and linkage are removed, they must be reinstalled correctly.
The actuator must be rotated so that the valve seats properly for close off.
4. Install valve with the proper ports as inlets and outlets. See drawings on
page 2 and 4. Check that inlet and outlet of 2-way valves are correct;
check that the “A” and “AB” ports of three-way valves are piped correctly.
Flow direction arrows must be correct.
5. Blow out all piping and thoroughly clean before valve installation.
6. Clean male pipe threads with wire brush and rag. If threads have been
damaged or exposed to weather, running a tap or die over the threads
may straighten them. Clean pipes, threads, and valve threads before
installation; check for any foreign material that can become lodged in trim
components. Strainers should be cleaned after initial startup.
7. Pipe sealing compound should be applied sparingly after cleaning and
may not be applied to the two lead threads of a screwed pipe, which are
innermost inside the valve. Sealing compound is to be placed on male
threads only. The purpose is to lubricate the pipes when tightening.
Mounting
The flange allows the actuator to be either parallel or perpendicular to the
pipe; there are four orientations possible.
If field installing a spring return actuator, disconnect power and allow actuator
to spring closed. Flip actuator over if necessary to achieve proper rotation
direction. DO NOT USE THE REVERSING SWITCH TO DO THIS.
Two-Way Valves Mounting
For NORMALLY CLOSED operation:
The ball of the valve must be rotated so that the ball is CLOSED to flow. The
actuator should be mounted with the clamp fully rotated CW (R). Spring
return actuators will show the CW (R) symbol near the clamp and position
indicator. Depressing the gear release to move the clamp rotates non-spring
return actuators.
For NORMALLY OPEN operation:
The ball of the valve must be rotated so that the ball is OPEN to flow. The
actuator should be mounted with the clamp fully rotated CCW (L). Spring
return actuators will show the CCW (L) symbol near the clamp and position
indicator. Depressing the gear release to move the clamp rotates non-spring
return actuators. There are marks on the top of the valve stem, which indicate
the port directions.
Do not force. Do not use the actuator to turn the pipe or the
stem. Do not use any toothed tool such as pliers, which may
damage the stem.
8. Valve must be installed with the stem towards the vertical, not below
horizontal.
9. Start the connection by turning the valve or pipe by hand as far as
possible. Be certain the threads mate by the “feel” of the connection.
•
Check that the actuator rotates so that the valve seats for close off and
also rotates open to achieve full Cv. Use the gear release or the AF
crank to verify. For LF or NF models apply power and control signal if
necessary.
•
Verify that CCW (L) rotation of the actuator will open the ball to flow.
•
Install and tighten the hold down screw not more than 1/2 turn beyond
the point where resistance is felt.
10. Use wrenches to tighten the valve to the pipe. Do not over tighten or strip
the threads. Two wrenches are necessary to avoid damaging the valve.
Warning!
Valve should not be used for combustible gas applications. Gas leaks and explosions may result. Do not install in systems, which exceed the
ratings of the valve.
•
Avoid installations where valve may be exposed to excessive moisture,
corrosive fumes, vibration, high ambient temperatures, elements, or high
traffic areas with potential for mechanical damage.
•
Avoid excessive stresses. Mechanical support must be provided where
reducers have been used and the piping system may have less structural
integrity than full pipe sizes.
•
Valve assembly location must be within ambient ratings of actuator. If
temperature is below -22°F a heater is required.
•
•
The valve assembly will require heat shielding, thermal isolation, or
cooling if combined effect of medium and ambient temperatures –
conduction, convection, and radiation– is above 122°F for prolonged time
periods at the actuator.
Sufficient upstream and downstream piping runs must be provided to
ensure proper valve capacity and flow response. Five diameters in each
direction are recommended.
•
Life span of valve stems and O-rings is dependent on maintaining nondamaging conditions. Poor water treatment or filtration, corrosion, scale,
other particulate can result in damage to trim components. A water
treatment specialist should be consulted.
•
Normal thread engagement between male pipe thread and valve body
should be observed. Pipe run that is in too far will damage the valve.
•
Following standard procedure, a strainer should be installed before the
coil and valve or in another appropriate place in the system.
•
Visual access must be provided. Assembly must be accessible for routine
schedule service. Contractor should provide unions for removal from line
and isolation valves.

Installation
1. Inspect shipping package, valve, linkage, and actuator for physical
damage. If shipping damage has occurred notify appropriate carrier. Do
not install.
