Installation
1.
Inspect shipping package, valve, linkage, and actuator for physical damage. If
shipping damage has occurred notify appropriate carrier. Do not install.
2.
Install valve with the proper ports as inlets and outlets. Check that inlet and outlet
of 2-way valves are correct. Flow direction arrows must be correct.
3.
Blow out all piping and thoroughly clean before valve installation.
4.
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.
5. 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.
6.
Valve must be installed with the stem towards the vertical, not below horizontal.
7.
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.
8.
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.
9. Two-way valve Normally Open or Closed confi gurations must be verifi ed by
examining both the mechanical drawings and the valve and actuator.
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 traffi c areas with
potential for mechanical damage.
•
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.
• 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.
•
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.
•
Suffi cient upstream and downstream piping runs must be provided to ensure proper
valve capacity and fl ow response. Five diameters in each direction are recommended.
•
Life span of valve stems and O-rings is dependent on maintaining non-damaging
conditions. Poor water treatment or fi ltration, 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.
The fl ange allows the actuator to be either parallel or perpendicular to the pipe; there
are four orientations possible.
If fi eld 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 fl ow. 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 fl ow. 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.
Mounting
The valves can be mounted in any position, except stem below horizontal.
