Product Overview
The product complies with the national standard GB12235, with reasonable structure, reliable sealing, excellent performance and beautiful appearance.
The sealing surfaces of the valve disc and valve seat are made of stellite cobalt-based hard alloy surfacing, which is wear-resistant.
The valve stem has been tempered and surface nitrided, and has good corrosion resistance and scratch resistance.
Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.
The valve body has a complete range of materials, and the packing and gaskets are reasonably selected according to actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions.
The inverted seal is made of threaded seal seat or body surfacing of austenitic stainless steel. The inverted seal is reliable. Packing replacement and maintenance can be performed without stopping the machine, which is convenient and quick without affecting the system operation.
