Structural features:

1. The sealing surface of valve seat and gate adopts plasma spray welding machine to automatically surfacing cobalt-based hard alloy. The sealing surface has uniform hardness and HRC40-45 can be used under high temperature and high pressure conditions below 650℃, with wear resistance, corrosion resistance, abrasion resistance and long service life.

2, elastic single ram, elastic double ram design, to meet the requirements of different working conditions;

3, stem surface hardening and corrosion resistance treatment, easy operation, packing box seal reliable;

4, corrosion inhibition packing, special conditions using composite packing, to ensure no leakage;

5, can be matched with a variety of domestic and imported electrical equipment, to meet the DCS control requirements.
