P3Y Global Soft Start Valves offer a combined soft
start/quick dump or soft start only option that provides safe introduction of
pressure to a machine or system allowing the pressure to gradually build to a
set point before fully opening to deliver full flow at line pressure. These
valves can
be an important safety factor and prevent damage to tooling. These P3Y soft
start valves can be mounted using a modular connector to other P3Y global air
preparation products.
These valves should be
mounted downstream of the FRL and used in combination with valves and cylinders
as a main function of protection for machinery. Installation should be made with
the soft start needle easily accessible for manual adjustment. Pressure supply
piping must be the same size as the inlet port or larger, to ensure the pilot
valve receives sufficient pressure supply during high flow conditions.
Once installed a pilot signal
is received at the pilot operator, the valve shifts, closing the connection
between ports 2 and 3. At the same time, air flow begins between ports 1 and 2
at a slow rate, controlled by the needle valve located on top of the valve.
When the downstream pressure reaches approximately 60% of the supply pressure,
the main valve spool opens, allowing full flow through the valve in the system.
When using the P3Y combined
soft start/quick dump valve option, if the pilot signal or system pressure is
lost, the valve returns to its initial state, venting the downstream pressure
through its exhaust port.
Note: soft start valves are
not intended to be used as emergency shut-off valves but should be placed after
a manual shut off valve.
