| | | A. | Tri-Service Valves - Models FTV-S, FTV-A: |
| | | | 1. | Mount valve to a spool piece on the discharge side of the pump. Spool piece required is based on a minimum recommended space of 12 inches (305 mm) for pump sizes 2 inches by 2 inches (51 mm by 51 mm) to 6 inches by 6 inches (152 mm by 152 mm) and 24 inches (610 mm) for pump sizes 8 inches by 8 inches (203 mm by 203 mm) to 12 inches by 12 inches (305 x 305 mm). |
| | | | 2. | Do not mount valve directly to pump to avoid causing undesirable noise in the system. |
| | | | 3. | Leave sufficient clearance around valve for valve removal or repair. |
| | | | 4. | Install valve in the direction of flow arrows on valve body. |
| | | | 5. | Mount valve to flanged equipment using Gruvlok Flange Adapter or industry standard grooved coupling, suitable for system pressure and temperatures encountered. |
| | | | 6. | Valve body has been designed to handle the weight of the pump on vertical in-line installations. The valve body is not designed to support the piping weight. Support piping by hangers. Provide pipe supports under valve and strainer bodies. |
| | ** NOTE TO SPECIFIER ** Delete if not required. |

| | | B. | Globe Valves - Model GBV-S (Soldered), GBV-T (Threaded), Balancing Valves - Model GBV-G (Grooved-End Straight), GBV-A (Grooved-End Angle): |
| | | | 1. | To ensure accuracy of measurement of GBV-S, GBV-T, GBV-G and GBV-A valves, locate valves at least 5 pipe diameters downstream from any fitting and at least 10 pipe diameters downstream from a pump. |
| | | | 2. | Install no fittings within 2 pipe diameters downstream of valve. |
| | | | 3. | Install valves with flow in the direction of the arrow on the valve body. |
| | | | 4. | Provide easy access to probe metering ports (PMPs), drain ports and handwheel. |
| | | | 5. | For solder applications, solder valve body in line using 95/5 solder. |
| | | | 6. | Install valve-bonnet assembly into body, making sure non-asbestos gasket is in place. |
| | | | 7. | Install valves in horizontal or vertical piping as indicated. |
| | | | 8. | Do not install metering ports below the pipe (pointing down), as this will allow system sediment to accumulate in the ports. |
| | | | 9. | Metering ports and body/drain plugs may be interchanged for improved accessibility. |
