Liner<br />
To specify liners add L suffix to part number and advise of specific movements to<br />
properly size liner. On combination ends specify flow direction.<br />
Cover<br />
To specify covers add C suffix to part number<br />
NOTES<br />
1. Rated cycle life is 5000 cycles for any<br />
one movement tabulated minimum per<br />
EJMA.<br />
2. To combine axial, lateral or angular<br />
movements the sum of each must not<br />
exceed 100%. Refer to pages 36 to 43.<br />
3. To obtain greater movements or cycle<br />
life contact <strong>Thorburn</strong>.<br />
4. Maximum axial extension movement is<br />
50% of tabulated axial value.<br />
5. Maximum test pressure: 1-1/2 x rated<br />
working pressure.<br />
6. Catalogue pressure ratings are based<br />
upon a design temperature range of -<br />
20ºF to 800ºF. Actual operating<br />
temperature should always be<br />
specified.<br />
7. For higher pressure temperature,<br />
movement and cycle ratings, contact<br />
<strong>Thorburn</strong> with your application details<br />
for fast action.<br />
