RZMO-TERS Hydraulic Proportional valve AERS pressure 315bar Flow 4L/min
RZMO are poppet type hydraulic proportional
pressure relief valves, direct operated with
integral or remote pressure transducer,
which provide pressure regulation
proportional to electronic reference signals.
They operate in association with electronic
drivers, see section , which supply the
proportional valve with proper current to
align valve regulation to the reference signal
supplied to the electronic driver.
