12 valves and in Wafer or Single flanged style (NPS
2 available in wafer only)
Maximum Inlet Pressure
(1)
Carbon Steel and Stainless Steel Valve Bodies:
Consistent with CL150 and 300
pressure/temperature ratings per ASME B16.34
unless limited by material temperature capabilities.
NPS 2 is also consistent with CL600.
Maximum Pressure Drops
(1)
Consistent with CL150 and 300 pressure‐temperature
ratings per ASME B16.34 except for PTFE, UHMWPE
and Phoenix III seals which are derated at some higher
pressure‐temperature values. Refer to figure 2
Shutoff Classifications
J
PTFE, Reinforced PTFE, and UHMWPE
(3)
Seals:
Bidirectional shutoff to Class VI per ANSI/FCI 70‐2 and
IEC 60534‐4.
J
NPS 2 Metal Seal:
Bidirectional shutoff. 0.001%
of maximum valve capacity (1/10) of Class IV per
ANSI/FCI 70‐2 and IEC 60534‐4. Maximum Pressure
drop is 51 bar (740 psi) forward and 6.9 bar (100 psi)
reverse.
J
NOVEX Seal:
For NPS 3 through 12. Unidirectional
shutoff is 0.0001% of maximum valve capacity (1% of
Class IV) in the reverse flow direction per ANSI/FCI
70‐2 and IEC 60534‐4.
J
Phoenix III Seal:
For NPS 3 through 12. Bidirectional
shutoff to Class VI per ANSI/FCI 70‐2 and IEC 60534‐4.
For the optional
Phoenix III Fire‐Tested seal, consult your
Emerson
sales office
or Local Business Partner.
Flow Characteristics
Approximately linear
Disc Rotation
Clockwise to close (when viewing from the drive shaft
end) through 90 degrees of disc rotation (see figure
10)
Flow Direction
See figure 3
Actuator/Valve Action
With the diaphragm or piston actuators, the valve
action is field‐reversible. Refer to information in the
Installation section.
Valve Classification
Face‐to‐face dimensions of NPS 3 through 12 are in
CL150 and 300, and meet
API 609 or MSS‐SP‐68 standards for face‐to‐face
dimensions of wafer‐style and single flange valves.
Shaft Diameters
See table 2
Approximate Weights
See table 2
ENVIRO‐SEAL Packing
This optional PTFE or graphite packing system
provides excellent sealing, guiding, and transmission
of loading forces to control liquid and gas emissions
(see figure 8). See bulletin 59.3:041 ENVIRO‐SEAL
Packing System for Rotary Valves (
D101638X012
) for
more information.
1. The pressure/temperature limits in this manual and any applicable standard or code limitation for valves should not be exceeded.
2. For components selection and applicable fire tested standards and codes, consult your Emerson sales office.
3. UHMWPE stands for ultra high molecular weight polyethylene.
