Note: Automated PLC Pigging systems control the upward and downward
movement of the primary and secondary launch pins which are gas
driven utilizing pipeline gas pressure. The PLC driven controls
require a 24 VDC power supply. The System will launch spherical pig
either at the control panel locally, or on a pre-determined time
intervarl, or from a remote signal. Optional hydraulic or electric
driven pins are available. A valve control panel can be provided for the valves
equipped with actuators. Standard units will hold 10 spherical pigs
up to the 12" size and 8 spherical pigs in 14" and larger sizes
