Li etselitsoe ho fihlela litlhoko tse hlakileng tsa bareki ba Europe, li-valve tsa rona li na le tekanyo ea khatello ea 300lbs, li latela maemo a bohlokoa a moralo oa API 6D. Li entsoe ka thepa ea boleng bo holimo, ho kenyeletsoa ASTM A216 WCB bakeng sa 'mele, ASTM A217 CA15 + N bakeng sa polaka, le ASTM A182 F6a bakeng sa kutu, li-valve tsa rona li netefatsa ho tšoarella le ts'ebetso e sa bapisoang.

E 'ngoe ea lintlha tsa bohlokoa tsa li-valve tsa rona ke bokhoni ba tsona ba ho mamella mocheso ho fihlela ho +330°C, e leng se etsang hore li be ntle bakeng sa lits'ebetso tse hlokang ts'ebetso ea mocheso o phahameng. Ka moralo oa BARE STEM o ntlafalitsoeng bakeng sa li-actuator, kopanyo e se nang sekoli lits'ebetsong tsa hau e tiisitsoe.

Ho Nortech, boleng ke ntho ea bohlokoa ho rona.
