 1. DESCRIPTION
1.1. GENERAL
According to DIN 2429, HYDAC
3/2 way ball valves are units
system pressure system pressure
which shut off and divert the flow diverted
shut off
of an operating medium.
The 3/2 way ball valves are
available in nominal bores
DN 04 - 25.
These ball valves have the
following advantages:
– Visual indication of the switching
position by means of a slot on the system pressure
control spindle
– Switching limited by means of
stop pin and stop disc
– Support ring on the control
spindle seal
– No glands, therefore no manual
re-adjustment of seals required
– Sealing principle with floating ball,
sealing on the outlet side
– Full flow passage for unrestricted
flow of medium
– Easy operation
– Compact design
– Surface phosphate-plated or
yellow zinc-plated
HYDAC ball valves are available A Housing E Stop pin
