Figure 2. Available Seal Configurations

Notes:
This unidirectional seal must be installed so that the retaining ring is downstream from the high pressure side of the valve at shutoff, as shown.
For this bidirectional seal, the “preferred” valve orientation places the retaining ring downstream from the high pressure side of the valve at shutoff.
NPS 3 only.
