Features

Valve parts in contact with the medium undergo strict low-temperature treatment according to the specifications before precision machining to ensure that the valve parts can fully withstand the expansion and contraction caused by temperature changes, and the structure of the valve seat will not undergo permanent deformation due to temperature changes.

Valve seat and disc sealing surface using cobalt chromium tungsten hard alloy overlay structure.

Adopting a built-in bracket structure to avoid leakage of the medium at low temperatures.

Welded sleeves can be provided according to user requirements.
