Insertion Valve Sample Clauses
An Insertion Valve clause defines the terms and conditions under which a valve can be installed into an existing pipeline system without shutting down the flow. This clause typically outlines the technical requirements for the valve, the procedures for its installation, and any safety or operational standards that must be met. By specifying these details, the clause ensures that maintenance or upgrades can be performed efficiently and safely, minimizing service interruptions and reducing operational downtime.
Insertion Valve. 1. Insertion type valves shall be resilient wedge gate valves designed to be installed into an existing pressurized potable water main without interruption of flow through the pipe and no reduction of line pressure.
a. Valve shall be fusion-bonded epoxy coated in compliance with AWWA C550.
b. The construction of the resilient wedge shall comply with AWWA C509 requirements.
c. The resilient wedge shall be fully encapsulated with EPDM rubber and shall seat on the valve body and not the pipe. The resilient wedge shall be totally independent of the carrier pipe.
d. Valve shall be restrained to the pipe.
e. Valves shall be suitable for operating pressures up to 250 psi.
Insertion Valve. Insertion valves shall be measured on an individual basis on the number of each size valve acceptably installed. Three-dimensional survey shall be measured as one lump sum for a complete and accepted survey. This item will be included in the overall pipe measurement. No separate payment for this work.
Insertion Valve. Insertion valves shall be paid for at the unit price per each size valve inserted and shall cover the cost for all materials, transportation, labor, equipment, excavation, sheeting and shoring, installation of the valve, valve boxes, fittings, restraints, concrete pad or collar, valve identification disc, valve marker, polyethylene encasement, protection of existing utilities, chlorine for disinfection, disinfection, sampling points, backfilling, backfill material, disposal of unsuitable backfill materials, tamping, testing, densities, dewatering, trench stabilization, clean-up, restoration, and all work and materials necessary to install the insertion valve and place it in service.
