Stem: Lifting and lowering the stem, which is easy to operate while ensuring sealing.

Gland bolts: Double-head bolts are used, which is easy to disassemble the packing.

Process hole: easy to disassemble the sealing ring retaining ring.

Bracket: Double rib design, good rigidity.

Graphite sealing ring: It can maintain a good seal even under instantaneous high temperature conditions.

Hard sealing surface: high heat resistance, corrosion resistance and wear resistance.

Elastic wedge gate: The elastic wedge gate is one piece and is completely guided by the casting guide; it can adapt to the deformation of the valve seat caused by the thermal effect and the load of the connecting pipe; it can ensure the reliability of the seal under the low pressure difference working condition; it can avoid harshness Under working conditions, the gate plate and the valve seat are bonded or warped; it can be used in high-pressure, high-temperature steam conditions and other occasions that have strict requirements on valve closing tightness and reliability.
