closes valve) and
J push‐down‐to‐open (extending actuator rod
opens valve)
Valve Body Classification
NPS 14 to 24: Face‐to‐face dimensions are in
compliance with MSS SP68 and API 609 standards.
Valve bodies are designed for installation between
ASME B16.5 CL150 and CL300 raised‐face flanges
NPS 30 to 36: Valve bodies are designed for
installation between ASME B16.47 CL150 and CL300
raised‐face flanges
Disk Rotation
Clockwise to close (when viewing from the drive shaft
end) through 90 degrees rotation
Shaft Diameter and Approximate Weight
See tables 3 and 4
ENVIRO‐SEAL™ Packing
This optional packing system provides improved
sealing, guiding, and transmission of loading force to
control liquid and gas emissions. Contact your
Emerson Process Management sales office for
availability of ENVIRO‐SEAL packing
1. The pressure/temperature limits in this manual, and any applicable code or standard limitation should not be exceeded.
2. Ratio of maximum flow coefficient to minimum usable flow coefficient may also be called rangeability.
Description
The valve is available in either a flangeless wafer body or a single‐flange (lugged) body design, with a variety of seals
and internal components. The pressure‐assisted seal provides tight shutoff. The upper (splined) shaft combines with a
variety of pneumatic piston or spring‐and‐diaphragm actuators. Maximum inlet pressure/temperature ratings are
consistent with CL150 and CL300.
