2. WARNINGS
a) In order to avoid possib e injury to personne or damage to any equipment any
‘WARNING and CAUTION’ notes must be strict y adhered to.
b) Modification of this product, substitution of non-approved components and use
of maintenance procedures other than those detai ed within this document cou d
drastica y affect the performance, nu ify any warranty and be hazardous to
personne and equipment.
c) Persona injury, equipment damage, eakage due to escaping gas or fai ure of
pressure containing component may resu t if the va ve or anci aries are over
pressured or insta ed where service condition exceed the imits detai ed in the
manufacturer’s specification or on the va ve namep ate. To avoid such injury or
damage a re ief va ve for over pressure protection shou d be provide as required
by industry and sound engineering practices or app icab e safety codes.
d) Due to the possibi ity of both e evated and ow temperatures occurring on
exposed surfaces of the va ve assemb y during operation, adequate safety
precautions must be taken. This may invo ve insu ating the va ve assemb y or
the provision of safety c othing and equipment to avoid persona injury.
e) It is a requirement of PER 1999 that both the maximum working pressure and
temperature of the va ve are detai ed on the namep ate. The stated va ues must
be adhered to separate y and in iso ation. Attention must be paid to the
combined pressure and temperature characteristics of the appropriate va ve
pressure containment materia group as stated in ASME / ANSI B 16.34.
f) When purchased each va ve / trim configuration and construction materia s are
specifica y se ected to satisfy the particu ar app ication, conditions of f ow,
temperature, pressure drop and contro ed f uid conditions for corrosion and
erosion. Inc uded within the Pneucon Va ve se ection process is the
consideration of the amount of power conversion a owed to reduce vibration
eve s within the va ve and a so the materia s of construction are specifica y
se ected for each app ication. The va ve must not be used on any other
app ication, without a review by Pneucon Va ve.
g) The va ve is not suitab e for fire safe service and is not certified for this
app ication or duty. Un ess otherwise detai ed in the quotation and order
documentation the va ve wi not have been designed to dea with excessive
seismic activity or bending moments resu ting from misa igned pipe work.
h) It is not intended that externa y app ied ever arms wi be used on the va ve and
actuator assemb y.
)
For cage guided va ve, use of strainer is recommended to remove ine debris to
protect any damage to va ve interna so as to have smooth movement of p ug in
cage.
