4.6. Safety lnstructions for Inspection and
Installation work
4.6.1. General
On an actuated valve the operating instructions of the valve must be
strictly followed as well as those of the operating instructions of the
actuators, the limit switch or automation boxes.
The user is responsible for ensuring that all inspection and installation
work is carried out by authorized, adequately qualified staff who are
thoroughly familiar with this instruction manual.
Any work on a valve may only be performed when the valve is
un-pressurized and has cooled down to 60° C.
Any work on actuated valves may only be done after the actuator has
been disconnected from its energy supply. The procedure described
in the operating instructions to shut down the actuator must be
observed.
Valves in contact with hazardous media must be decontaminated.
Immediately following completion of the work, all safety relevant and
protective devices must be reinstalled and/or re-enabled.
Refer to the points listed under section 8 Commissioning.
4.6.2. End of line installation
Use as end of line and downstream dismantling at ambient
temperature of standard range.

NB: A valve fitted at the end of a pipe with a blind flange
downstream is not to be considered as an end of pipe service.
4.7. Unauthorized Modification
The equipment shall not be altered or modified in any way prior to
consultation with the manufacturer. The manufacturer cannot be held
responsible for damage resulting from the use of non--genuine parts or
accessories.
4.8. Inadmissible Modes of Operation
Operational safety and reliability of the valve supplied is only
warranted for its designated use as defined in section 3 "General" of
the operating instructions.
The limits stated in the technical documentation must not be
exceeded under any circumstances.
5. Transport & Interim Storage
5.1. Transport
The valves in the as-supplied condition are ready for operation.
ATTENTION For Transport and storage, the valves must always be
maintained in the semi--closed position and be packed in cardboard.
ATTENTION To prevent damage, do not hang the valve by its neck,
handle or actuator.
After delivery or prior to installation, the valve should be checked for
damage during transit.
5.2. Interim Storage
The valves must be stored in such a way that correct operation is
assured even after prolonged storage. This comprises:
-- Storing at 5 ° from the closed position
-- Suitable measures against contamination, frost and corrosion .

6.2. Functioning principle
The valve consists mainly of a body, operating shaft, shaft , disc and
rubber liner.
The in--house designed formulated and manufactured rubber liner
achieves the leak tightness at shaft passages, pipe flanges and
downstream/upstream around the disc.
Disc- -shaft connection: The disc and shaft connection is achieved
by a forced fixing of the shaft to the disc.
Operation: The valves are quarter--turn operated manually
handles or gear box or electric actuators bolted on the valve top plate
(as per ISO 5211 standard).
This valve is maintenance free.
7.

Installation

7.1. General
ATTENTION To avoid leakage, deformation or rupture of the body,
the piping should be laid out in such a way that no thrust or bending
forces act on the valve bodies when they are installed and operational.
ATTENTION
The sealing faces of the flanges must be clean and
undamaged (Ra ≤ 25μm).
