The Cla-Val 131VC-1 Electronic Control System is
designed to achieve unprecedented valve control
accuracy and stability. Ideal for remote valve control,
the 131VC-1 Electronic Control System provides the
interface between SCADA system computers and
hydraulic control valves sites.
Electronic Control of Hydraulic Valves
The 131VC-1 Electronic Control System is designed to work in
conjunction with Cla-Val 131 Series hydraulic control valves—
a combination that takes advantage of the simplicity of
hydraulic valve operation and the control possibilities available
with electronics.
The 131VC-1 Electronic Control System receives transmitted
signals and activates dual solenoid pilots on the hydraulic con-
trol valve. These pilots direct hydraulic pressure within the sys-
tem to position and regulate the valve. By continuously com-
paring system conditions to the programmed set-point, the sys-
tem is automatically maintained at the desired value.
Additional important control features, unique to this type of
valve control, are offered as standard. They are designed for
user friendly operation and system safety and are addressed in
this brochure.
