Industrial fittings 

Huta Małapanew Sp. z o.o. is a manufacturer of castings for valve wedges (switch-valve type) and other ones with passages from DN 40 to DN 1200. Castings are made of cast carbon steel and alloy cast steel.
We offer castings for the following installations:

  • power,
  • heat
  • refinery
  • chemical
  • gas

We manufacture also all types of other steel castings in line with individual requirements of our clients and on the basis of our production capabilities.

We manufacture cast carbon steel and alloy cast steel bolts and valves

  • valve wedges for power industry, heat engineering, chemical industry and refinery and other:

cat. No. 043, 43A, 055, 0554, 122SW, 122, 190S

  • refinery bolts (ZR 150 type)
  • side valves (P.I-29 and K.I-30 types)

The fittings are mainly made of castings from cast carbon and alloy cast steel depending on the purpose and clients’ orders.
