Bonnet: The gland bolts are designed with slip-knot bolts, which are easy to disassemble.

Valve seat: Sealed surfacing method is adopted to reduce the valve seat caused by external pressure

Deformation; its surface is hardened to ensure good wear resistance and resistance

Corrosive.

Bracket: Double rib design with good rigidity.

Stem: After precision grinding to ensure the sealing and smooth operation process, the stem

The upper part is fixed by mechanical threads to improve toughness and enhance durability.

Graphite sealing ring: It can still maintain a good sealing effect under low pressure and high pressure, even in the case of instantaneous high pressure and high temperature.
