6 The Special Sealing Design Applied In All Anti-tamper*. Astava Instrument Monoflanges Features A. Non-Rotating Ceramic Ball Tip. T-bar The chemical composition of a ceramic ball tip is superior in Locking device hardness and functionality to a metal ball tip, eliminating sealing tip deformation and significantly increasing the life time of the product. The stem threads are rolled and an integrated back seat design is applied to the packing type of bonnet. Applying a Stainless Steel 316 Ti stem with a chromium carbide diffusion coating results in maximum operation cycles and minimal risk of stem galling.

7 Both packing and O-ring bonnets are designed with sealing below stem threads for maximum protection of the stem threads. For maximum safety, the bonnet design prevents stem blowout, and a locking pin prevents unintentional disassembling of the bonnet. HANDLE OPTIONS. The standard handle of the ASTAVA Line of Instrument PRESSURE AND TEMPERATURE RATING Monoflanges is a Stainless Steel T-bar. For high pressure applications of 10,000 psi (690 bar) an extended T-bar or hand Temperature ( F) wheel can be applied.
