Product Features
Valve components parts that contacted with themedia before deep process must be strict cryogenic treatment according to therequirement of the specifications, to ensure valve parts can fully undertemperature change and cause inflation,contraction ,and the structure of seatpart will not have permanent deformation due to the temperature change
Cobalt chromium tungsten carbide overlayingwelding structure of the seat and gate sealing surfaces
The built-in yoke structure, to avoid externalleakage in low temperature medium
Welded nipples is available on request
Low leakage is available upon request. Detailtechnical requirements please refer to the low leakage sample
