Series MD
soft start valves
Ports with interchangeable cartridges: threaded (1/8, 1/4, 3/8) or
integrated with super-rapid fitting for tube with Ø 6, 8 and 10 mm
Modular assembly
The soft start valves are used to avoid
the sudden movement of pneumatic
actuators.
Feeding them pneumatically is enough to
begin the phase of the pressure gradual
increase in the system. By means of
a regulation screw, it is possible to
determine the time the valve needs to
reach the 50% of the inlet pressure.
Once this value is reached, the valve
opens completely the passage.
The blanked connection on the upper
side allows either the time increase to
fill the system through a small additional
volume or the connection of a pressure
switch.
» » Security function to maintain
the command sequence
» » Opening of the main air
path at about 50% of the
value of the inlet pressure
» » Upper air intake to connect
a pressure switch or to
extend switching time
» » Additional air intakes with
the same characteristics
of the outlet air (line)
