ASCO Solenoid/Air Controlled Soft-Start Devices
A soft-start device allows for gradual pressurization of the downstream equipment. An adjustable air flow causes the actuators to move slowly, and prevents damage from machinery being started at full speed. It can also return machinery to a safe, end-of-cycle position before re-starting.
Solenoid/Air Controlled Soft-Start allows the user to specify when the device switches to the full flow position. Position sensors on the machinery trigger the energization of the solenoid pilot valve. The solenoid pilot valve is energized under normal operating conditions, and upon de-energization the device switches to the low flow position.
The shut-off and soft-start units must be installed after the filter and before the lubricator.
