Valve Body Style Wafer (angeless) and single ange with tapped holes
Face-to-Face Dimensions Meets MSS SP68, API 609, and EN 558 standards
Shutoff
PTFE seal ring - Class VI per ANSI/FCI 70-2 and IEC 60534-4.
S31600 (316 SST) seal ring - 0.001% of maximum valve capacity [1/10 of Class IV
per ANSI/FCI 70-2 and IEC 60534-4]
Flow Directions
Standard (forward ow) is with the seal retainer facing upstream; reverse ow is
permissible within specied pressure drop limitations
Flow Characteristic Equal percentage (characterized disk)
Global standards
The Control-Disk valve meets API, ASME, and EN
standards, making it suitable for use in all world
areas. It has ISO 5211 actuator and NAMUR VDE/
VDI 3845 accessory mountings.
Excellent emission control capabilities
Optional ENVIRO-SEAL packing systems are
designed with very smooth shaft surfaces. Live
loading provides improved sealing, guiding,
and loading force transmission. The seal of
the ENVIRO-SEAL packing system can control
emissions to below 100 ppm (parts per million).
Sour service capability
Control-Disk valve trim and bolting materials are
available for applications involving sour uids.
These constructions comply with MR0103 and
MR0175/ISO 15156.
Application assistance
Specify a Fisher Control-Disk valve from Emerson
to keep quality on spec, output on target, your
facility on stream, and operations on budget.
