Selecting the Correct Size
Select the PPS1 RSIF valve according to both the PPS pipe outside diameter and the required female thread size. The first measurement in the variant name identifies the PPS pipe OD, while the second identifies the female threaded connection.
For example, 2" OD x 1-1/2" FNPT identifies PPS1 RSIFA50207 for 2" PPS pipe with a 1-1/2" female threaded connection.
Installation Considerations
- Confirm the PPS pipe outside diameter before ordering.
- Confirm the required female thread size.
- Verify compatibility with the mating threaded component.
- Review published dimensions for available installation space.
- Allow adequate clearance for full valve handle operation.
- Use compatible PPS piping and system components.
- Keep threaded, connection, and sealing surfaces clean during installation.
- Use appropriate sealing practices for the threaded connection.
- Provide appropriate support for connected piping and equipment.
- Do not exceed the published maximum operating pressure of 232 PSI.
- Maintain the system within the published -4°F to 176°F operating temperature range.
- Test the completed connection before normal system operation.
