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.
