Shut-off and regulating valves

Main page / Pipeline equipment / Shut-off and regulating valves

Industrial, technological and main pipeline valves, by rules ISO, EN/DIN, ASME/API, GOST etc.

  • material design – of carbon / alloy / stainless steel, non-ferrous metals and alloys. Chemical industry valves maybe also designed of special plastic, ceramic materials, PTFE
  • mounting length and process connections are sized by EN/DIN, ANSI, GOST. Mixed attributes are also available (e.g. ANSI length / DIN flanges)
  • special connections such as wafer, lug, butt weld ends
  • pressure range up to 400 bar (class #2500), for wellhead valves – up to 2500 bar (class #15000) 

the sign  marks double block & bleed valves with guaranteed zero leakage


multi-turn valves

  • gate valves with flexible or solid wedge
  • globe valves with flat or elliptic disc
  • slab gate or dual expanding gate valves
  • pinch valves for abrasive or corrosive media
  • plug/gate DBB valves
  • knife gate valves for bulk or abrasive media


quarter-turn valves

  • ball valves of different design
    • fully-welded, split of 2 or 3 parts, top entry
    • floating or trunnion ball
    • special types of seats – spring loaded, metal-by-metal
  • butterfly valves
    • centric, 2х and 3х eccentric
    • special types of seats – metal-by-metal, lined etc.
  • plug valves
  • diaphragm valves


flow and pressure regulating/control valves

  • regulating globe valves with conical disc
