Válvula Globo Criogênica

A cryogenic globe valve is made to specifically withstand temperatures below freezing point in industrial applications. Geralmente é feito de aço inoxidável e bronze. Ele também vem com um capô estendido para proteção contra temperaturas extremas.

Introdução de Produtos

The valves which operated below -40℃ usually call cryogenic valves. It mainly used in ethylene, liquefied natural gas plants,natural gas LPG, LNG storage tanks, receiving bases and satellite stations,empty Sub-equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid hydrogen, liquid nitrogen, liquid argon, carbon dioxide low temperature storage tank and tank truck, pressure swing adsorption oxygen system.

características do produto

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

Using the long neck bonnet structure that can protect the stuffing box

No matter how the temperature change it can maintain the disc reliable seal, globe valve use cone disc

Back seal seat cobalt chromium tungsten carbide surfacing welding structure, to avoid the stainless steel material Scuffing each other

Cobalt chromium tungsten carbide overlaying welding structure of the seat and gate sealing surfaces

The flow direction of medium is lower end in inlet and higher end in outlet higher( inflow from the disc lower end);Stem surface nit riding hardening process, to prevent valve in the process of opening and closing surface scratches affect the sealing performance

Packing chooses fugitive emission packing on request, ensuring valve packing place leakage to meet environment requirements

Welded nipples is available on request;Insulation board (drop water board) is available on request

Low leakage can be chosen upon request, detalhes dos requisitos técnicos, consulte a amostra de baixo vazamento.

Material

Nota: Material can be chosen upon request.
