A "push-to-open" Manual Relief Valve that is similar in construction to and mounts in the same hole as the TA327 Pressure Relief Valve.  Side venting design permits pressure equalization even when the button is depressed by personnel wearing arctic gloves.  May open automatically at vacuum pressures above 6.0 psid.  Can be mounted through a 0.51 in. (13 mm) diameter hole.  Part No. TA317, without hex nut, installs in a 0.500-20 UNF-2B threaded boss.

Materials and Finish: Housing is aluminum with anodized finish.  Weight: 0.046 lb. (21 grams)

Mounting Requirements: Each valve comes complete with nut and o-ring.
Mounting hole diameter: 0.51 ± 0.01 (13 ± 0.25 mm)
Installation torque: 30-40 in. - lbs. (3.4-4.5 N•m)
Maximum wall thickness: 0.14 (3 mm)
Add washer for wall thickness less than 0.03 (1 mm). (P/N MS15795-855, order separately.)
For threaded boss installation: 0.500-20 UNF-2B; 0.51 ± 0.01 (13 ± 0.25 mm) diameter X 0.02 (1 mm) minimum deep counterbore required for thread relief. Part No. TA317 comes without hex nut.
