Product Features
Valve components parts that contacted with the media before deep process must be strict cryogenic treatment according to the requirement of the specifications, to ensure valve parts can fully under temperature change and cause inflation, contraction ,and the structure of seat part will not have permanent deformation due to the temperature change.
Cobalt chromium tungsten carbide over laying welding structure of the seat and gate sealing surfaces.
The built-in yoke structure, to avoid external leakage in low temperature medium.
Welded nipples is available on request.
Low leakage is available upon request. Detail technical requirements please refer to the low leakage sample.
Main components parts combination.
