Steel wedged-gate valves ZKS (ЗКС)

 

Full-opening  wedged-gate valves ZKS with rising stem are used as locking device on pipe lines, processing lines of oil-refining, chemical,  petrochemical, gas, paint and varnish industries, transporting liquid and fluid working mediums.

 

 

 

 

 

 

Characteristics:

  • Gate valves’ shut-off joint parts are made of stainless steel with advanced durability:

          o 30x13 – spindle;

          o 30x13 – wedge;

          o 20x13 – bush.

  • Valve body is forged and made of:

          o alloy steel 18HGT (18ХГТ) for isolation of non-aggressive media (water, steam, natural gas, air, nitrogen, inert gases, fuel oil, oil distillates, diesel fuel, diesel oil, petroleum and petroleum products);

          o cold-resistant steel 09G2S (09Г2С);

          o stainless steel 12H18N10T (12Х18Н10T) for isolation of food and aggressive mediums (steam, natural gas, drinking water, liquid food products, alcohol, acids, alkalines, dry chlorine and chlorine gas, phosphorus and its inorganic compounds).

 

Parts, made of austenitic steel, are checked on intergranular corrosion resistance according to GOST 6032-75.
