CBV1/2-10
Counterbalance valve
For 4:1 Ratio
Pilot pressure, =
Cracking pressure + (5 x Port 2 pressure) - Port 1 pressure
4
For 10:1 Ratio
Pilot pressure, =
Cracking pressure + (11 x Port 2 pressure) - Port 1 pressure

A - Piloted open port 1 to port 2
B - Free flow port 2 to port 1
Description
The CBV*-10 is a 3-ported,
externally piloted, screw-in
cartridge type counterbal-
ance valve.
Operation
The CBV counterbalance
valve allows free flow from
port 2 (inlet) to port 1 (load).
Flow from port 1 to port 2
is blocked until either the
predetermined pressure
setting has been reached or
sufficient pilot pressure has
been applied to port 3
(pilot).
