V280 Valve
August 2019

Specifications

Valve Sizes and End Connection Styles
NPS J 6, J 8, J 10, J 12, and J 16 flanged valve
size with CL900 raised-face flanges compatible with
ASME B16.5. Consult your
other end connection styles
Maximum Inlet Pressure and Temperatures
Consistent with CL900 pressure-temperature ratings
per ASME B16.34
Maximum Allowable Shutoff Pressure Drop
For Single-Seal and Dual-Seal Construction (except
where further limited by pressure-temperature rating
of the valve body):
CL900: 153.2 bar (2220 psig) at 38°C (100°F)
Shutoff Classifications
Single or Dual-Seal Construction
Class IV standard: ANSI/FCI 70-2 and IEC 65034-4
Class VI optional: ANSI/FCI 70-2 and IEC 65034-4
Flow Characteristic
J
Modified linear with single high-density attenuator
J
Modified equal percentage with single
characterized attenuator
J
Modified equal percentage without attenuator
Flow and Shutoff Direction
Unidirectional flow is forward flow. Seal is upstream
Single Seal Construction: Should be used for
unidirectional flow and unidirectional shutoff only
Dual Seal Construction: V280 with Aerodome and
unattenuated V280 may be used for unidirectional
and bidirectional flow
V280 with Hydrodome should be used for
unidirectional flow only for effective anti-cavitation
protection. Bidirectional shutoff requires dual seal
construction
1. The pressure or temperature limits in this bulletin and any applicable standard or code limitation for this valve should not be exceeded.
2. PTFE stands for Polytetrafluoroethylene and PEEK stands for PolyEtherEtherKetone.
