KTM RICHARDS FIGURE R382/R384/R392/R394 BALL VALVES
INSTALLATION AND OPERATING INSTRUCTIONS
Installation and operating instructions for:
R382, DN 15 - 50 reduced bore; R384, DN 15 - 50 reduced bore;
R392, DN 8 - 40 full bore; R394, DN 8 - 40 full bore
MAINTENANCE
The only routine maintenance required is
periodical checks and adjustment to the
stem assembly. Adjustment to the gland
nut is recommended after the first 5000 and
10000cycles; and every 10000 cycles thereafter
to compensate for the bedding of thrust and
gland seal and ensure leak free operation.
When tightening the gland nut, do not exceed
recommended torques, see table overleaf. After
reaching recommended gland nut torque, back
off to nearest flat on nut. Bend the lock washer
over the nut in this position.
When fitting actuators to valves, refer
to mounting instructions supplied with
mountingkit.
SAFETY PRECAUTIONS
Whenever a valve is being installed or removed
from the pipeline, ensure the line is not
pressurized and any hazardous medium is
drained away. Slowly cycle the valve several times
to relieve the cavity area and leave in the open
position.
Check that the seat and body pressure ratings
aresuitable for the service prior to installation.
These ratings must not be exceeded.
PIPE COMPATIBILITY
Emerson ball valves are suitable for installation
into most piping systems. The standard end
connections are:
• BSPT
• NPT
• Socket weld pipe Sch. 40
• Socket weld O/D tube Sch. 10
• Butt weld pipe Sch. 40
Other end connections are available upon
request.
STORAGE INSTRUCTIONS
The valves ball, seats and end connections
should be adequately protected against
damage.
The protective end covers should not be
removed until ready for installation.
GENERAL
All valves are bi-directional, controlling flow
in either direction. They can be installed in any
position, horizontally or vertically.
Thread tape or sealant is recommended to
ensure effective sealing. Check that the tape/
sealant is suitable for the service.
INSTALLATION
Prior to leaving the factory each valve is
pressure tested, and to prevent damage to the
ball surface and seats protective covers will
have been fitted. Leave these in place until
such time as the valve is ready for installation.
On removal make sure the valve is in the open
position and free of foreign matter.
When installing valve, follow relevant standards
and statutory regulations.
Examples:
Local gas fitting regulations, municipal building
codes or electrical wiring regulations.
a) Screwed valves: valves should not be
dismantled prior to fitting, and installed as
a unit following standard piping practice
(eg.using thread tape or pipe sealant).
When screwing the valve to the pipe
DO NOT OVERTIGHTEN.
b) Weld valves: follow instructions for weld
valves (see overleaf).

WELDING INSTRUCTIONS
CAUTION: failure to follow these instructions
could result in serious damage to the valve seats
and seals.
1. To prevent weld splatter damaging the ball
surface and to facilitate the later removal of
the center section, ensure the valve is in the
open position.
2. Locate the valve in the pipeline and tackweld
the valve in position.
3. Loosen and remove the body bolts (010)
and nuts (011), allowing the body (001) to
be removed from between end connectors
(009). For R384 and R394 valves only - extra
care must be exercised at this stage as the
body will not slide out from between the
end connectors unless the pipe ends are
separated sufficiently to give clearance for
the raised fire lip and the spigot on the end
connectors. Damage to either the fire lip
or the spigot will effect the integrity of the
valves body seal (012) and the secondary
metal to metal seal of the ball and fire lip in
a fire condition.
When removing the body (001), ensure the
body seal (012) and seats (101) remain in the
original locations.
OPERATION
All Emerson ball valves are quarter turn.
Handle operated valves provide visual
indication of the valve position. When the
handle is across the line of the valve, the valve
is closed, and when the handle is in line with
the valve, the valve is open. Stops are integral
with the valve and only Emerson handles must
be used.
Actuated valves are available and Emerson
has various options of pneumatic and electric
actuators.
For further details on fitting actuator, refer
tothe mounting instruction sheet.

INSTALLATION AND OPERATING INSTRUCTIONS
4. Complete welding process, taking care
to protect the sealing faces of the end
connectors from weld splatter. Allow
cooling of the ends before reassembly.
5. Reassembly:
a) Check the body seal (012), seats (101) and
ball (100), making sure they are clean,
undamaged and in original locations and
that the ball is in the open position.
b) Check sealing faces of end connectors
(009) to ensure the surface is clean and
not damaged by weld splatter.
c) Relocate the body (001) between end
connectors (009), taking care that the
pipe ends are sufficiently apart to provide
clearance to slide the center section into
position between the ends. For R384 and
R394 valves only - care should be taken
not to damage the fire lip and spigot on
the ends. Make sure the end connector
spigots fit in the body seal grooves.
Replace body bolts (010) and nuts (011)
and retighten to recommended torques.
6. Inspect for leakage at plant start-up and
adjust if necessary.
CAUTION: if seats or seals are in any way
damaged, do not reassemble valve without
replacing damaged components.
