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.

UP (on

horizontal

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).
