Data Sheet
ECO80LS EVB-HPCO
ECO80LS High Pressure Carry Over
ECO80LS EVB-HPCO (High Pressure Carry Over) is
module designed to deliver excess pump flow
downstream of the ECO80LS valve to other open
center valves
Features
•
Full pressure and flow available to
downstream open center valve while
ECO80LS valve sections are not in use.
•
Enables the standard EVP inlet “T” port
to function as “HPCO” port.
•
Includes “T” port for ECO80LS return
flow to reservoir
•
Includes pilot pressure supply
eliminating the need for EVP inlet pilot
supply.
•
Includes adjustable LS relief valve
controlling max working pressure to
ECO80LS valve.
•
Include fixed shock valve facility (PVLP)
for pressure peak protection to
downstream open center valve.
Benefits
•
Manages all open center (fixed) pump
flow while adding priority to ECO80LS
functions
•
Reduces the number of pumps and
plumbing connections to multiple open
center valves
