KTM RICHARDS FIGURE R382/R392 BALL VALVES
INSTALLATION AND OPERATING INSTRUCTIONS
Installation and operating instructions for:
• R382, DN 65 - 100 reduced bore ball valves
• R392, DN 50 - 80 full bore ball valves
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.
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.
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
The R382/R392 are bidirectional valves,
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).
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.

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).
When removing the body (001), ensure
the body seals (012), seats (101) and seat
retaining ring (103), remain in the original
locations.
4. Complete welding process, taking care
to protect the sealing faces of the end
connectors (009) from weld splatter. Allow
cooling of the ends before reassembly.
5. Reassembly:
a) Check the body seal (012), seats (101),
ball (100) and seat retaining ring (103)
making sure they are clean, undamaged
and in original locations and that the ball
is in the open position.
TORQUE VALUES (Nm)
Valve size DN Body bolts
Note: R382 DN 65 - 100 valve illustrated
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. 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.
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.
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.
