FEATURES
GENERAL APPLICATION
TECHNICAL DATA
Ideally suited for many industrial applications
such as food and beverage, pulp and paper,
chemical, mining, water treatment, HVAC,
power, and automotive where a heavy-duty
resilient seated butterfly valve is required.
Available in a wide variety of body, disc and
seat materials to fit a wide variety of media
applications.
Size range:
DN 50 to 900 (NPS 2 to 36)
Wafer and lug styles
Pressure rating: DN 50 to 300 - 17.2 bar
(NPS 2 to 12 - 250 psi)
DN 350 to 600 - 13.7 bar
(NPS 14 to 24 - 200 ps)
DN 750 to 900 - 10.3 bar
(NPS 30 to 36 - 150 psi)
PTFE seat or elastomer
covered disc
DN 50 to 300 - 10.3 bar
(NPS 2 to 12 -150 psi)
Dead end rating: Full rated in preferred
direction of flow
(Lug style only)
Flange standard:ASME Class 125/150

• Suitable for high pressure and full vacuum
service due to the use of a cartridge seat
design.
• Triple function cartridge seat isolates the
body and stem from the media, provides
positive drop-tight shut-off of line media at
full rated pressure and provides a flange seal,
eliminating the need for flange gaskets.
• Full rated unidirectional dead-end service is
achieved by utilizing a unique patented lip in
the lug body.
• Strong disc-to-stem connection and
elimination of exposed pins or bolts is
achieved through a rectangular drive.
• Ability to install the valve with the disc in the
closed position eliminates the risk of damage
to the valve during installation.
• Maximum flow and rangeabililty is achieved
with the use of a streamlined disc.
• Blowout-proof stems as a standard.
• Longer seat life with low operating torques
is ensured by utilizing upper and lower stem
bearings.
• Need for costly brackets is eliminated due to
the ability to direct mount actuation onto the
valve top-plate.
• Designed to comply with MSS-SP-67 and
API 609 (may be shell tested to spec request)

KEYSTONE SERIES 60 BUTTERFLY VALVE
METRIC DATA
VALVE SIZING
Rate of flow through a valve depends upon the pressure drop. The most common method of
presenting this information is by Kv. The Kv is the valve coefficient of flow and represents the
volume of water in cubic meters per hour (m³/h) that will pass through a valve with a pressure
drop of 1 bar at 21°C. The higher the Kv, the greater the flow and the better the control
characteristics. Throttling characteristics are shown in the same manner with Kv’s at the various
disc openings. Tabulated below are the Kv’s for the Series 60 Butterfly Valve.

TORQUE DATA
Torque is the rotary effort required to operate a valve. This turning force in a butterfly valve is
determined by three factors - the friction of the disc and seat due to interference for sealing,
bearing friction, and fluid dynamic torque.
Breakaway torque at 21°C
Breakaway torque is the total of the torques resulting from bearing friction and disc/seat
interference friction at a given pressure differential. Listed below are torques to open and close
the valve at pressures shown in wet services (normal conditions).
NOTE
These values are valid for water and lubricating fluids only at 21°C. Since torques are greatly increased for dry
and nonlubricating fluids and temperature variations, contact your Keystone representative for accurate values
in these applications.

IMPERIAL DATA
VALVE SIZING
Rate of flow through a valve depends upon the pressure drop. The most common method of
presenting this information is by Cv. The Cv is the valve coefficient of flow and represents the
volume of water in gallons per minute (GPM) that will pass through a valve with a pressure drop
of 1 psi at 70°F. The higher the Cv, the greater the flow and the better the control characteristics.
Throttling characteristics are shown in the same manner with Cv’s at the various disc openings.
Tabulated below are the Cv’s for the Series 60 Butterfly Valve.

Breakaway torque at 70°F
Breakaway torque is the total of the torques resulting from bearing friction and disc/seat
interference friction at a given pressure differential. Listed below are torques to open and close
the valve at pressures shown in wet services (normal conditions).
NOTE
These values are valid for water and lubricating fluids only at 70°F. Since torques are greatly increased for dry
and nonlubricating fluids and temperature variations, contact your Keystone representative for accurate values
in these applications.
