Valve Body Style
Flangeless (wafer-type) valve body to be installed
between pipeline flanges
End Connection Styles
Flangeless (wafer-style) valve body mates with
CL125 flat-face flanges per ASME B16.1, with
CL150 and 300 raised-face flanges per ASME
B16.34, or EN flanges
Maximum Allowable Inlet Pressure (1)
Consistent with applicable pressure/temperature
ratings for
JCL125B per ASME B16.1, or
JCL150 and 300 per ASME B16.34 unless
limited by maximum allowable pressure drop
specification or by material temperature
capabilities in table 2
Vacuum Service
The valve is suitable for vacuum service to
approximately 10
-7 mm Hg absolute

Installation
WARNING
Always wear protective gloves,
clothing, and eyewear when
performing any installation operations
to avoid personal injury.
Personal injury or equipment damage
caused by sudden release of pressure
may result if the valve assembly is
installed where service conditions
could exceed the limits given in table 1
or on the appropriate nameplates. To
avoid such injury or damage, provide a
relief valve for over-pressure
protection as required by government
or accepted industry codes and good
engineering practices.
Check with your process or safety
engineer for any additional measures
