The structure is novel, the structure is novel, and the valve is communicated with the upper cavity, and the upper and lower pressure self balancing can be achieved by the structure of the API and the relevant standards. The composite packing is adopted, which is reliable in sealing, and the friction force is small. Sealed with live seat structure. Surfacing cemented carbide. Valve can be installed in horizontal or vertical pipe.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
