- 1. All parts should be clean to assure the best results.
- 2. The pipe with the companion flanges installed should be properly supported and aligned. Be sure the companion flange is flush with the face of the valve body flange and lined up squarely.
- 3. Use a gasket material (not provided) that is recommended for the medium being handled.
- 4. See Figure-5 for flange and flange bolt details. Figure-5 also shows the proper way a flanged valve should be mounted.

- CHECKOUT
- 1. Make sure the valve stem operates freely before installing the valve linkage and the actuator.
- 2. If the stem does not operate freely, it may indicate that the valve was twisted or crushed during installation or that the stem was bent by rough handling. These conditions may require that the valve be replaced.
- 3. After the piping is under pressure, check the valve body and the connections for leaks.
- 4. After the valve linkage and the actuator are installed, check their operation.
- a. Drive the actuator and run the valve to the stem down position. Make sure the linkage and valve stem move freely. At the stem down position, the valve should shut off the “B” port.
- b. Drive the actuator and valve to the stem up position. Again, the valve stem and linkage should operate smoothly. At the stem up position, the valve should shut off the “A” port.
- 1. Make sure the valve stem operates freely before installing the valve linkage and the actuator.
