SECTION 15050 (CONT.)
Basic Mechanical Methods and Materials
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 ftting and at least 10 pipe diameters downstream from a pump.
2. Install no fttings within 2 pipe diameters downstream of valve.
3. Install valves with fow 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.
