The valve is intended for installation in fully enclosed pipework,
when installed the pipework will prevent access to the moving
parts. The valve must not be used if either connection remains
open.
Care must always be exercised when removing and installing the
rotor. Beware of trap points and sharp edges paying particular
attention to the vane edges, the end cover/body interface and the
interconnection of the rotor shaft in the drive hub and tail piece.
Beware also of other personnel in the vicinity who may come into
contact with the moving rails.
Deterioration of the gland seals can lead to leakage along the
shaft and there will be some product retention in the housing
when the valve is opened for cleaning or maintenance. Proper
provision for dealing with any potential leakage of the conveyed
material must be made by the end user.
The valve is fitted with hexagonal headed dome nuts to prevent
direct access to the valve internals. If the valve is intended to be
RVB90.40.R.EN.Issue A
ROTOR
If the valve is being fitted in an extreme temperature installation it
must be appropriately protected so as not to cause injury.
2.2 Check the valve externally for damage and internally for foreign
objects. Install the valve using compressible gaskets on both
flanges; the valve body must not be stressed or used to support
ancillary equipment. Valves must be installed the correct way
up, i.e., with the slide rails horizontal and below the valve centre
line. Air purge shaft seals (if fitted) must be connected to a
regulated clean dry air supply at a pressure 0.33 bar (5 p.s.i.)
above the maximum static pressure in the valve.
2.3 The motor must be connected to a suitable electrical supply in
accordance with the manufacturer’s nameplate / operation and
maintenance instructions. Check that the Geared Motor Unit is
filled with lubricant, in accordance with the manufacturer’s
instructions. Top up or fill as necessary. Check that the valve
rotates in the correct direction. Check the arrow on the drive
guard or gearbox. The valve is now correctly installed and ready
to operate.
2.4 Connect the end cover release switch to a suitable control circuit.
It should ensure the motor supply is isolated if the valve is not
closed correctly; switch details are provided with this manual.
NOTE! The end user/installer is responsible for the control system
connected to the valve.

The speed has been set at our factory for the duty and
throughput required.
The valve performance is related to that of the system and any
major departure from the specified throughput will require
investigation.
Failure of the valve to maintain its performance may indicate
excessive wear and the valve clearances should be checked.
BLOCKAGES: Are normally symptomatic of problems elsewhere
in the system and if this is the case then these are the
responsibilities of others.

Rota Val Ltd FCT Rotary Valves are designed to require
minimum maintenance: however, regular attention in accordance
with the following instruction will prolong valve life.
BEARINGS
Standard bearings are greased packed and sealed for life, no
maintenance being necessary. Bearing should be checked for
wear and damage every 3 months or 2,500 hours and replaced if
necessary. REPLACE EVERY 12 MONTHS OR 10,000 HOURS
(See DISMANTLING and REASSEMBLY).
SHAFT SEALS
Seals are not adjustable so leakage can only be cured by
replacement.
AIR PURGE
Ensure that air passages to the lantern ring do not become
blocked.
GEARED MOTOR UNITS
Geared units are proprietary and are to be maintained in
accordance with manufacturer’s instructions - provided with this
manual.
Wear and tear within the Rotary Valve is always uneven, usually
affecting all internal components.
Some improvement of
performance may be achieved by replacing the most worn
component(s), the improvement in most cases will be marginal
and temporary.
C L E A N I N G
Isolate all electric and pneumatic connections before proceeding.
Ensure that any cleaning products used are compatible with the
product being handled.
EXTRACTING ROTOR FROM VALVE
6.1 Ensure the feed into the Rotary Valve is clear of product and

Inspection of internal surfaces can be performed with reference
to cleaning instructions, sections 6 & 7. Check all surfaces for
scoring and wear, any high spots may be eased away using
emery cloth, a smooth file or grind stone. Acceptance of deep
score marks or excessive wear will depend on the duty
requirement and the characteristics of the media handled. If in
doubt consult our technical sales department.
Refer to
maintenance section for wear limits.
Check rotor shaft ends for burrs, dress away as necessary using
emery cloth, smooth file or grind stone. Check seal journals for
wear, any excessive wear in this area will require replacement of
rotor or alternatively the area may be built up using a recognised
cold reclaim technique and reground.
Inspection of internal components seals, bearings etc. may be
carried out after reference to dismantling instructions, sections
10 & 11. Check journals on Tail Piece (2.5), Bearing Support
Sleeve (2.11) and Drive Hub (3.2) for wear. Check Bearing
