Flow characteristics (90° open, 100% open Cv (Kv))
Cv (Kv): USgpm at dP=1 psi, 68°F (m3/h at dP=1 bar, 20°C)
Flow @ 29psi dP
Leakage Characteristics
The F2 Emech ceramic shear action valves have bubble tight (zero leakage) shut-off. The Emech seat seal performs beyond the re-
quirements of ANSI B16.104 and FCI 70-2 Classes V and VI.
Body Pressure Rating - Designed to ASME B16.34
Operating Pressure @ <257°F (125°C) psi (bar)

Notes:
(1) Note G12 actuator is recommended for 3/4" (20 mm), 1" (25 mm), and 1 1/2" (40 mm) F2 sizes. The G1.3 is recommended for the F2
size 2" (50 mm) valve.
• All specifications are for water.
• Flows are quoted without terminal fittings, restrictors, or non-return valves on the inlets. (Non-return valves are recommended.)
• If operating at more than one maximum rated condition, contact Armstrong to confirm the application is appropriate.
