Gate Valves. Gate valves shall be paid for at the unit price per each size gate valve and box assembly installed and shall cover the cost for all materials, transportation, labor, equipment, excavation, sheeting and shoring, installation of the gate valves (including valve box), concrete pad or collar, valve identification disc, valve marker, valve tag, polyethylene encasement, protection of existing utilities, chlorine for disinfection, disinfection, backfilling, backfill material, disposal of unsuitable backfill materials, tamping, testing, densities, utility crossings, dewatering, trench stabilization, clean-up, restoration, and all work and materials necessary to install the gate valve and place it in service.
Gate Valves. Gate valves shall be measured on an individual basis for each size valve and box assembly acceptably installed.
Gate Valves. Flanged, raised face, wedge, ASTM A-216 Gr WCB cast steel bodies, OS&Y and bolted bonnets. Valve trim shall have a proven 10 year service life in similar geothermal service, for example stellite or 316 sealing surfaces and 17-4 PH valve stem. Valve specifications shall be submitted to Company for approval and verification prior to order by Contractor.
Gate Valves. A. Resilient seated gate valves shall meet AWWA C515 or C509 and be UL listed and FM approved. This valve shall be ductile iron-body, bronze mounted, non-rising stem, 3-inch through 12-inch in diameter as shown on the Drawings. All valves shall open RIGHT. All valves shall be mechanical joint.
Gate Valves. The buyer will provide the necessary vacuum gate valves for connection the stand-by pumping system (turbomolecular and roughing pump) and the gate valves for connection of the output flanges to the beam duct of the tokamak. All other vacuum valves are the responsibility of the Seller, e.g. valve between the Vacuum tank assembly and Ion source assembly.
Gate Valves. Gate valves shall be paid for at the unit price per each size gate valve and box assembly installed and shall cover the cost for all materials, transportation, labor, equipment, excavation, sheeting and shoring, installation of the gate valves encasement, protection of existing utilities, chlorine for disinfection, disinfection, backfilling, backfill material, disposal of unsuitable backfill materials, tamping, testing, densities, utility crossings, dewatering, trench stabilization, clean-up, restoration, and all work and materials necessary to install the gate valve and place it in service.
Gate Valves. All gate valves shall comply with the requirements of SABS 664 and shall carry the SABS mark. Gate valves shall completely clear the bore of the valve in the fully open position. The direction of closing shall be clearly marked on the bonnet of the valve. Xxxxx shall be drip-tight from zero to maximum working pressure under test conditions.
Gate Valves. The Contractor removes all old gate valves on the polyelectrolyte dosing system and disposes of them according to the Employer’s waste management procedure. The Contractor supplies and installs new gate valves on the polyelectrolyte dosing system including new gaskets, reducers, extensions, spacers, supports, brackets, bolts, nuts and washers etc., where required. The Contractor supplies the relevant datasheets, material certificates, hydrostatic pressure test certificates, final inspection reports and safety clearance certificates for all valves. 25 mm Gate Valves: o Quantity: Seven (7) o Type: Brass Manual Gate Valve, Internally Threaded o Rating: PN 16 o Size: 25 mm o KKS List: Table 40: 00 xx Xxxx Xxxxxx XXX List Functional Loc.
