Application & Features:
1. It's serciced where the heat preservation of fluid is needed, such as equipment of polyester, ethylene, pitch, urea, etc.
2. Body including inlet and outlet flanges are heat preserved, so the effect is very well, the function of vapor flushing be added if neeeded.
3. Balanced bellows construction protects set pressure from being affected by variable back pressure, and the parts in bonnet, such as spring, from being corroded.
4. Trim(nozzle and disc) is normally made with austenitic stainless steel, and faced with stellite alloy.
5. To meet specail service, the material of trim can be 316LN, 0Cr25Ni6Mo3CuN, 00Cr25Ni6Mo2N, F51(UNS S31803), F53(UNS S32750), F55(UNS S32760).
