VALVOLE ACCIAIO - CORAL

Ball valve in stainless steel, of solid and advanced design is backed by the twentyyear experience gained by ENOLGAS
in production of ball valves. In order to keep tolerances and material quality constant, investment casting of body
and end adapter was preferred to forging, with careful subsequent toolings on CNC machines,
which guarantee a high quality standard. Leading design and accurate machining and finishing
of the valves guarantee a perfect tightness and lifetime troubleless working operations.



 
  WORKING PRESSURE
PN 105 series 1500
PN 64 series 800
  TEMPERATURE LIMITS
From -20°C to +150°C
  UTILISATION
CORAL is suitable for use in high pressure and high temperature condiction.
For special uses, see the table of chemical resistance.
TECHNICAL FEATURES
Full bore
The machining of the body and end connection
  takes place on CNC high precision machines,
so as to guarantee the compliance
with the design specifications.
Possibility of stops at 90° by operation without lever.

Nm
Values in Nm can change depending
  on the material used for seats,
on temperature and on the fluid used.
For a safe working of the various sorts
of servocontrol, it is necessary to consider
a safety factor = 1,5 in each condition.
While the valve is working, with frequent
on/off cycles, the operationg torque
can become extremely low in comparison
with the beginning one.
