Fluoroplastic Seats for Ball Valves

Sealing ring for ball valves are fabricated in accordance with:
  • Clients' drawings
  • TU2291-001-49990416-2001 (finished fluoroplastic parts)
  • TU6-05-810-88 (PTFE)
  • TU6-05-1413-76 (F420, F515, F4155, F4155)
  • GOST10007-80 (guidelines applicable to fluoroplastic powder)

Our company fabricates sealing rings (seats) for ball valves. We produce PTFE seats for valves with DN 10-300 mm to be operated under pressures of 6 to 20 MPa and seats made from PTFE compounds (F420, F4155, F515, F5155) for valves to be operated under pressures of 16 to 40 MPa.
Characteristics of some compounds:
F415 - increased strength as compared to F4, including improved pressure deformation characteristics, wear resistance, chemical resistance and plug/ball surface "polishing" properties of the material;
F4155 - improved strength and reduced fragility as compared to F415; addition of molybdenum disulfide (MoS2) leads to formation of an additional protective coating on the mating metal surface which increases wear and corrosion resistance of the sealing seat and plug (ball); also, this compound has a better coefficient of friction which reduces efforts required for valve opening/closing. This compound is the material of choice for valves operated in liquefied gas media.
All parts can be fabricated to Clients' drawings or technical documents.
