Structural features:

1, the whole series of valve body forging process, smooth appearance, uniform organization, high strength, meet the high temperature and high pressure operating safety requirements;

2, spherical seal high hardness, wear resistance and corrosion resistance, effectively prolong the service life;

3, self-sealing design, good sealing performance, no leakage;

4, valve stem surface by precision grinding and hardening treatment, anti-abrasion corrosion, effectively reduce the opening and closing torque, easy operation;

5, the use of special corrosion inhibition filler structure design; Avoid the stem surface corrosion, avoid leakage;

6, all kinds of intelligent electrical configuration, realize remote automatic control and field control;

7, lifting rod design, plane bearing effectively reduce operating force.
