Specifications include, but are not limited to:
The actuators shall be mounted on four existing Plug Valves located in Decant
Structures 8A and 8B. Each Decant Structure has two 16-inch eccentric plug
valves to be equipped with automatic actuators. The equipment ID tags for the
LAGN_8A_VPG_3681_13 (previously noted as Valve 13A-3608-VP)
LAGN_8A_VPG_3681_14 (previously noted as Valve 14A-3608-VP)
LAGN_8B_VPG_3682_13 (previously noted as Valve 13B-3608-VP)
LAGN_8B_VPG_3682_14 (previously noted as Valve 14B-3608-VP)
Automatic actuators shall be used for full opening and closing of the plug valves.
A remote control station will be installed in the controls room above the installed
valve, with the capability to operate the valve in Local mode. When the control
station is set to Auto, the valve will automatically open and close based on the
PLC logic. Limit switches will send a digital feedback signal to SCADA indicating
the valve position. See SCADA standards in Section 00 30 00, Appendix A.
