! WARNING

s

The safety precautions in these operating
instructions are specially marked with the
standard symbol for danger when
non-observance could result in personal injury,
loss of life or property damage.

! CAUTION

l

Non-observance of these safety precautions
can endanger the valve and its functions.

0.1.1 QUALIFICATIONS AND TRAINING
OF PERSONNEL

The personnel responsible for operation,
maintenance, inspection and assembly must be
appropriately qualified.

The operating company must precisely define the
responsibilities, competence and supervision of the
personnel. If the personnel lack the necessary
knowledge, they are to be trained and instructed. If
required this can be carried out by the
manufacturer/supplier of the valve by order of the
operating company. Furthermore, the operating
company is to ensure that the contents of the
operating instructions have been fully understood by
the personnel.

OPERATOR

If hot or cold components of the valves are a

-

source of danger, these components must be
secured against contact by operating company.

Contact guard for moving parts may not be

-

removed when valve is in operation.
Do not hang items off the valves. Any

-

accessories must be firmly or permanently
attached.

Do not use the product as a step or hand hold.

-

Do not paint over identification tag, warnings,

-

notices or other identification marks associated
with the product.

Plastic PTFE diaphragms emit toxic fumes due

-

to thermal decomposition at temperatures of
716°F (380°C) or greater.

0.1.5 SAFETY PRECAUTIONS FOR
MAINTENANCE, INSPECTION AND
ASSEMBLY

Work on externally actuated valves should only be
carried out when the valve is removed from service.
Valves that have been exposed to harmful media
such as caustic chemicals must be decontaminated.

On completion of work, all safety and protective
equipment must immediately be fitted again or
reactivated.

Before the re-operation, attention should be paid to
the points in the following sections.

0.1.2 DANGERS THROUGH
NON-OBSERVANCE OF THE SAFETY
PRECAUTIONS

The non-observance of the safety precautions can
result in the endangering of lives as well as the
environment and the valve. The non-observance of
the safety precautions can lead to the loss of all
claims for damages.

Non-observance can result in the following:

-

Failure of important functions of the valve/plant.

-

Endangering of lives by electrical, mechanical
and chemical influences.

-

Endangering the environment through leakage
of dangerous materials.

Personal injury or property damage.

0.1.3 SAFETY AWARENESS AT WORK

Attention must be paid to the safety precautions in
these operating instructions, the current national
regulations concerning the prevention of accidents as
well as any labor, company and safety-regulations of
the operating company.

0.1.4 SAFETY PRECAUTIONS FOR THE
OPERATING COMPANY / INDIVIDUAL

0.1.6 UNAUTHORIZED
RECONSTRUCTION AND MANUFACTURE
OF SPARE PARTS

Reconstruction or modification of the valve is only
admissible after consultation with the manufacturer.

Genuine spare parts and accessories authorized by
the manufacturer serve to maintain safety. The use of
other parts can annul all liability for the
consequences.

Manufacturer's parts are not to be used in conjunction
with products not supplied by the manufacturer. The
use of manufacturer's parts with products not supplied
by the manufacturer can annul all liability for the
consequences.

0.1.7 INADMISSIBLE MODES OF
OPERATION

The operational reliability of the valve supplied is only
guaranteed when used as designated. The operating
limits given on the identification tag and in the data
sheet may not be exceeded under any circumstances.

If the product label is missing or worn contact
manufacturer at the address listed within this manual
for specific instructions.

0.2 TRANSPORT AND STORAGE

! WARNING

s

The universally recognized technical standards
and the regulations regarding prevention of
accidents must be observed at all times when
handling.

0.2.1 TRANSPORT

The goods have to be carefully handled in order to
prevent damage.

The end flange caps supplied are to be fitted to the
valve as applicable.

0.2.2 UNPACKING

Unpack the shipment, check to make sure that all
contents are present and undamaged.

0.2.3 STORAGE

If the valve is not to be installed immediately following
delivery, it must be properly stored.

Storage should be in a dry room at a temperature as
constant as possible. Product should not be stacked
on top of one another.

Storage over a longer period may necessitate
individual moisture proof packing. This is dependent
on the local conditions.

0.2.4 DISPOSAL, RECYCLE OR RETURN
SHIPMENT

The personnel responsible for disposal of the product
or associated components are to comply with
federal, state and local requirements.

If the return shipment is required, contact
manufacturer at the address listed on backpage for
specific instructions.

! WARNING

s

The operator of valves used for aggressive or
toxic media such as caustic chemicals must
ensure that these are well flushed and cleaned
before being handed to the maintenance
personnel. This is particularly important when
returning to the product manufacturer,
disposing of or recycling the product or its
component parts. MSDS are required for
authorization to return valves to the
manufacturer.

1.0 INSTALLATION

1.1 BONNET ASSEMBLY TO BODY INSTALLATION

This section to be followed when assembling a bonnet
assembly including diaphragm and backing cushion to
a valve body.

1.1.1 Prior to assembly to the body, the
diaphragm/backing cushion should be resting flat
against the bonnet flange. The compressor should be
extending just short of the full closed position. Rotate
the input shaft to achieve this position.

1.1.2 Position the bonnet over the studs and onto the
body. Drop washers over the studs.

1.1.3 After the bonnet assembly is positioned over the
studs and rests against the body, lightly lubricate the
studs with Chevron Poly FM2 just above the bonnet
flange (i.e. the location at which the nut will engage the
stud when tight against the bonnet).

1.1.4 Assemble nuts finger tight. Final tightening of
bonnet fasteners shall be done by hand. Pneumatic
tools are not permitted. Bring the torque up gradually
with at least 3 passes on each nut. Nuts shall be
tightened in a crisscross pattern, so as to compress
the diaphragm evenly. Tighten nuts securely to 10
ft-lbs (120 in-lbs, 13.5 N-m).

! CAUTION

l

Nut assembly torque requirement of 10 ft-lbs
(120 in-lbs, 13.5 N-m) is critical to the success
of the valve's sealing function. Excessive
torque decreases the valve's sealing function
and increases the amount of effort required to
actuate the valve.
