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).

Wiring

Wiring is dependent on the type of actuator and

the desired options that are available. Consult the

actuator model label and then the relevant sections

in the

MEP-7500/7800 Series Actuators Installation

Guide

for detailed instructions on the applicable

wiring, feedback selector, and actuator/signal range

reset (auto-mapping) of the valve’s actuator. (See the

More Information section on the next page.)
