Back-to-back check/shuttle valve with signal at port 2
SERIES 1 / CAPACITY: 10 L/min. / CAVITY: T-11A
The back-to-back check valve combines two simple check valves into a single cartridge. It connects the work port
with the higher pressure to the signal or common port. The signal is sensed at port 2.

TECHNICAL FEATURES
Back-to-back check cartridges feature hardened, spherically lapped, guided poppets and a lightly stressed helical spring that result in excellent wear characteristics
and extremely low leakage rates.
The back-to-back checks do not provide a means of lowering a signal. They will trap a high signal if the load pressures drop to a lower pressure. Some means of
bleeding off the signal should be provided.
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.
