Table 1. Specifications
Valve Sizes(1)
NPS J1, J1-1/2, J2, J3, J4, J6, and J8.
DN 25, 40, 50, 80, 100, 150 and 200 sizes are also
available.
End Connection Style
JRaised‐face flanges, Jring‐type joint flanges
(ASME B16.5), Jor flangeless valve body designed to
fit between raised face flanges. JCL150, JCL300,
or JCL600; (CL600 is not available in NPS 6 and 8
flangeless valve bodies). DIN PN10 through PN100
flanges also available; consult your Emerson sales
office or Local Business Partner.
Maximum Inlet Pressure(2)
Consistent with applicable ASME B16.34 or
EN 12516-1 ratings
Shutoff Classification
Class IV per ANSI/FCI 70‐2 and IEC 60534‐4 (0.01% of
valve capacity at full travel), for either flow direction.
Leak rates for full and restricted port valves are based
on full port capacities. Reduced port valves seat at the
full port diameter.
Flow Characteristic
Modified linear
Flow Direction
JReverse Flow (Standard Direction): Past valve plug
and through seat ring tends to close the valve,
recommended for erosive and general service
JForward Flow: Through seat ring and past valve
plug; tends to open the valve, recommended for high
pressure drop and high cycle service
Actuator Mounting
JLeft‐hand or Jright‐hand as viewed from the
upstream side of the valve. See figure 2
Valve Plug Rotation
Counterclockwise to close (when viewed from
actuator side of valve) through 90 degrees of valve
plug rotation
Valve/Actuator Action
With diaphragm or piston rotary actuator,
field‐reversible between Jpush‐down‐to‐close
(extending actuator rod closes the valve) and
Jpush‐down‐to‐open (extending actuator rod
opens the valve)
Shaft Diameters(3) and Approximate Weights
See table 2
1. The Valve Size shown in this manual refers to Nominal Pipe Size (NPS).
2. The pressure or temperature limits in this manual and any applicable standard limitations should not be exceeded.
3. Shaft diameter and spline end must match available shaft diameter of actuator.
Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given on the appropriate nameplates, or the mating pipe flange
rating. Use pressure‐relieving devices as required by government or accepted industry codes and good engineering
practices.
Check with your process or safety engineer for any other hazards that may be present from exposure to process media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
CAUTION
When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,
pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve
