N O W . . . A New I m p r o v e d - D e s i g n 60,000 p.s.i. Valve by Autoclave Provides G r e a t e r Safety Prevents Unsafe Use of L o w e r Pressure Fittings
I n their continuous effort to improve the operation of high pressure equipment, $£, engineers and craftsmen offer you this new (^ improved 60,000 p.s.i. valve. You will recognize that these design improvements provide greater operational safety and prevent interchangeability with lower pressure fittings:
4. Weep holes are drilled at the base of the female thread of the valves and fittings. 5. Threads with rounded root are used throughout to prevent interchangeability with lower pressure fittings. 6. Threads on the gland are relieved to the base of thread to minimize stress concentration. 7. Female threads on valves and fittings are relieved at base of thread.
1. The outside diameter of both the collar and gland is increased for added strength and safety. 2 . The increased length of the gland permits longer thread engagement. 3. Internal corners are machined with a radius . . . corners on the collar are chamfered to minimize hazard at points of stress concentration.
8. All essential parts are 414SS heat treated to 100,000 p.s.i. minimum yield with 1 8 % minimum elongation. BULLETIN 455 GIVES COMPLETE DETAILS . . . IT'S YOURS FOR THE ASKING.
