Products Design Features

Flanged ends cast steel gate valve are used to cut or connect the pipe media under nominal pressure between PN 1.6 ~ 4.2.0 Mpa (Class 150 ~ 2500), working temperatures =< 600>

The main structure features include:

  1. Both design and manufacture are carried out strictly following GB/T12234, API600 and API602. The products feature a reasonable structure, reliable seal, good performance and nice modelling.
  2. Co hard alloy welded sealing surface, which is wearing resistant, erosion proof, abrasion proof and long-lived.
  3. The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistant.
  4. PN >= 15.0 Mpa (class900), the middle cavity uses a self-tightening sealing structure to have the sealing perfomance reinforced along with the pressure rise so as to ensure the sealing performance.
  5. There is no backward sealing structure in the vlave, so the sealing id reliable.
  6. The material of the filling and the flange size can be chosen and matched according to the applications and the requirements of the use's. That can satisfies all kinds of working requirements.
