Double flange available 28" to 48" valves.
Wafer body features four alignment holes.
Pressure ratings for tight shutoff at temperatures up to the
maximum limit of the seat material:
2" to 12" — 200 psi, 125 psi for PTFE/Buna seat.
14" to 48" — 150 psi.
Ideal for on-off or throttling services.
Available with handles (2" to 12"), manual gear operators
(2" to 48"), and electric or pneumatic actuators (2" to 48").

electric actuators.
Compatible with ASME B16.1 and ASME B16.5 flanges.
Valves 2" to 20" meet the intent and have passed the
AWWA C-504-87 Section 5 proof of design tests.
Type approval certification from ABS & USCG Category A
for marine applications (2" to 48").
Bi-directional dead-end capability to 200 psi (2" to 12")
and 150 psi (14" to 24") is standard on lug valves.
Operators mounted perpendicular to pipe.
For bolting information, consult the Center Line Installation and
Maintenance Manual.
Vacuum Service Rating: zero leakage at 24" of mercury.
Commercial cleaning available for Oxygen level 2.
CE/PED Certification available for sizes 2" to 24".
All torques shown in these charts were derived from test data using water
at 60°F. For torques using dry gases, multiply these numbers by 2.0. For
torques involving other media, please consult the factory.
There is no safety factor included in the numbers shown on these charts.
For actuator sizing, Crane recommends that these values be multiplied
by 1.2 for single valve applications, or 2.0 for 3-way (“tee”) applications.
For PTFE/Buna seats multiply the numbers shown by 2.0.
Under certain conditions, hydrodynamic torque can meet or exceed
seating and unseating torques. When designing valve systems,
hydrodynamic torque must be considered to help assure correct
selection for the application.

Although elastomers have an effective operating temperature
range, when used in valves, these ranges may have to be
modified. The temperature ranges shown in the table have been
adjusted accordingly.
For Low Temperature: While the seat materials selected for
use in Center Line butterfly valves are capable of withstanding
lower temperatures without damage, the durometer of the
elastomer is changed. This “hardening” of the seat may increase
the operating torque beyond the structural limits of the stem
and/or the disc to stem configuration.
For High Temperature: When using High Temperature Viton®,
the operating pressure of the valve is reduced above 275°F.
Field Replacement: Replacing seats in sizes 14" and above
requires factory service.
L1 and M1 refer to Lug style valves, L2 and M2 refer to Wafer Style. “C” dimension is listed with elastomer in the relaxed condition. Approximately 1/8" total compression is required
for proper sealing with pipe flanges. Valves are designed for installation between ASME B16.1 Class 125 (Iron) and B16.5 Class 150 (Steel) flanges. Gaskets are not needed, and should
not be used since the seat face seals against the mating flange. If the valve is to be installed in bet ween any other flanges, consult your Center Line agent or the factory for additional
information. Center Line recommends that a blind flange be used on end of line applications.
