The New River Regional Water Authority (NRRWA) is accepting proposals from suppliers to provide and install open/close actuators on two existing 20” butterfly valves within a control vault, replacing existing electric actuators which were damaged by flooding in the vault.
The supplier of the new actuators will be responsible for removing the existing actuators, installing new actuators, making power and control wire connections, and performing startup and training for the new equipment. Supplier shall also be responsible for verifying compatibility of new units with existing power and control signals, or making field adjustments necessary to allow proper operation from existing controls and provide open/close limit switch feedback.
The control valve vault is located near 2083 Chapman Road, Wytheville, Virginia. The controls are located in a separate above grade building approximately 150 feet to the east. Power and signal wiring is installed through existing conduit and is intended to remain in place and be reconnected to new actuators.
The NRRWA will be installing a sump pump within the vault and a float switch to provide remote alarming in the event of future flooding.
The following attachments are integral to this Request for Proposal:
- Existing 20’ Butterfly Valves (Original Submittal Data)
- Existing Actuators to be Replaced (Original Submittal Data)
