Cryogenic Globe Valve

A cryogenic globe valve is made to specifically withstand temperatures below freezing point in industrial applications. It is generally made from stainless steel and bronze. It also comes with an extended bonnet for protection against extreme temperatures.

Products Introduction

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.

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

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, detail technical requirements please refer to the low leakage sample.

Material

Note: Material can be chosen upon request.
