Mounting
1. Clean the lines upstream from the valve. Remove
any debris (welding slag, pipe scale, or other
contaminants) larger than 1/16 inch (1.6 mm).
NOTE: If the system experiences large amounts
of debris, steps should be taken to keep
the system clean, such as 20 mesh strainer
installed upstream of the valve.
2. Align the valve assembly according to the system
flow requirements (see the illustration below).
3. The valve may be mounted on either vertical or
horizontal pipe lines. On horizontal lines, mount
the valve so the actuator is positioned upright
and over the valve. (Leave sufficient room on all
sides to service the actuator and valve.)
CAUTION
To prevent condensation from dripping onto the
actuator housing on horizontal lines, mount the
valve with the actuator in the upright position or, at
most, at a 45° angle.
4. Install approved flange gaskets (not supplied by
KMC Controls) and bolt the valve to the pipes.
5. Eliminate air from the system to keep the valves
full of fluid during operation.

lines)
CAUTION
Using mineral oil lubricants or other incompatible substances in
system fluids may damage EPDM rubber seals in valves. Before
using any lubricant or additive in a water or ethylene glycol
base, consult the substance manufacturer for compatibility with
EPDM (Ethylene Propylene Diene Monomer).
