Table 1. Specifications

Valve Sizes

NPS J 2, J 3, J 4, J 6, J 8, J 10, or J 12

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 10-7mm Hg absolute

(3.4 x 10-12mbar, absolute)

Maximum Shutoff Pressure Drop(1)

Standard Operation

Cast Iron Valve: 12.1 bar (175 psi)

Steel or Stainless Steel Valve: 15.2 bar (220 psi)

Material Temperature Capabilities(1)

See table 2

Flow Characteristic

Conventional Disc: Approximately equal percentage through 60 degrees of disc rotation

Fishtail Disc: Approximately equal percentage through 90 degrees of disc rotation

Flow Direction

Conventional Disc: Bidirectional

Fishtail Disc: Forward flow – The tail of the disc opens into the downstream end of the valve (see figure 2).

Disc Rotation

Conventional Disc

On/Off Service: J 0 to 60 or J 0 to 90 degrees

Throttling Service: 0 to 60 degrees

Fishtail Disc: 0 to 60 or 0 to 90 degrees for on/off or throttling

Shutoff Classification per ANSI/FCI 70-2 and IEC 60534-4

Nitrile Liner or PTFE Liner: Class VI

Mating Flange Capabilities

All sizes compatible with welding-neck flanges; also see Installation section for slip-on flanges

Code Classifications

Dimensions meet MSS SP-67 specifications for face-to-face dimensions for flangeless valves

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
