»> Product Overview
The product design and manufacture is in accordance with the national standard ANSIB16.34, the American petroleum institute standard AP16D and API600 requirements.
The structure is compact, compact, rigid and reliable.
The closed parts (gate) adopt elastic structure and can automatically compensate the deformation of body due to abnormal load or temperature in the work. Therefore, the seal is reliable and does not produce gate wedge.
The nominal size is greater than or equal to NPS1011, and the pressure level is 400 pounds and the nominal size is greater than or equal to NPSS611, pressure level 150 ~ 2500 pounds of manual valve, and its operating equipment is equipped with rolling bearing, which is easy to open and close.
The material of the main body material, inner part material, packing, gasket and fastener can be combined according to user's requirement or actual working condition.
The seat can be a more open seat, which can be combined with the closing of the sealing material to meet the working conditions and extend the service life.
