Description
Product Features
The valve parts in contact with the medium are strictly low-temperature treated according to the requirements of the specification before finishing to ensure that the valve parts can fully withstand the expansion and contraction caused by temperature change, and the structure of the valve seat part will not be permanently deformed due to temperature changes.
The valve seat and disc sealing surface cladding with CoCrW.
Adopt the built-in bracket structure to avoid the leakage of the medium at low temperature;
Welding sleeves can be customized if needed.
