features:
1. The product is designed and manufactured according to API standard, with reliable sealing and excellent performance, and can be used with imported equipment.
The gate and valve seat seal above 600Lb is overlaid with Stellite cobalt based cemented carbide, which is wear-resistant, high-temperature resistant, corrosion-resistant, scratch resistant and has long service life
3. After quenching and tempering, the valve rod has good corrosion resistance and scratch resistance.
4. Wedge shaped elastic plunger structure, large diameter in rolling bearing, easy to open and close.
5. The material of valve body is complete, the packing and gasket are matched reasonably according to the actual working condition or user's requirements, which is suitable for various pressure, temperature and medium conditions.
The 6.1500lb and 2500lb middle chambers adopt pressure self tightening sealing structure. The sealing performance increases with the increase of internal pressure, and the reliability is high.
7. The inverted seal is made of stainless steel threaded joint seal seat or body surface austenitic stainless steel. The inverted seal is reliable. The replacement and maintenance of packaging can be carried out without stopping the machine. It is convenient and fast, and does not affect the operation of the system.
