CODD
20:1 ratio, pilot-to-close check valve
SERIES 1 / CAPACITY: 2,8 mm / CAVITY: T-11A
This valve is a spring biased closed, pilot-to-close check cartridge that has a 20:1 pilot ratio. The valve allows flow
from port 1 to port 2 and blocks reverse flow. Pressure at the pilot (port 3) opposes pressure at port 1 at a ratio of
20:1.
TECHNICAL DATA
Maximum Operating Pressure 350 bar
Maximum Valve Leakage at 110 SUS (24 cSt) 0,07 cc/min.

TECHNICAL FEATURES
Pressure at the port 2 area directly opposes pilot pressure.
Reverse flow through the valve from port 2 to port 1 is not possible under any condition.
The valve is a poppet design that results in very low leakage of stored fluid from the accumulator.
With equal pressures at all ports the valve is closed.
Capacity is the equivalent of a .109 in. (2,8 mm) diameter orifice.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
