Pressure self sealing cast steel globe valve

Overview and Application

Pressure self sealing cast steel globe valveThe valve stem has an upper sealing function, and the sealing surface is welded with CR13, hard alloy or body, wear-resistant, high temperature resistant, and has a long service life

Features:

The valve cover is equipped with a cooling chamber, which can reduce the aging phenomenon caused by temperature and improve the compensation and sealing performance of the packing; The gland bolt adopts a joint bolt design, which is easy to disassemble.

The bracket adopts a double reinforcement design, with good rigidity

The valve stem is precision ground to ensure smooth sealing and operation, and the upper part of the valve stem is fixed with mechanical threads to improve toughness and enhance durability

The valve seat is easy to replace and adopts a welding method, which can reduce the deformation of the valve seat caused by external pressure. Its surface has been hardened to ensure good wear resistance and corrosion resistance

Graphite sealing rings can maintain good sealing performance even under low and high pressure, and even under instantaneous high pressure and high temperature conditions
