Features

1. In order to prevent abnormal pressure increase in the middle cavity, pressure relief holes are set up on the inlet side of the ram
2, according to the working temperature of the valve to determine the top length of the valve cover, to ensure the reliable sealing of the valve stem packing
3, according to the working temperature reasonable selection of packing, gasket and other parts of the material
4, strictly control the chemical composition of the material and low temperature impact toughness and other mechanical properties indicators
5, the use of a variety of pipe flange standards and sealing surface types, suitable for various engineering needs
