 1. Flat straight bottom design, avoiding odds and ends healed up, which ensures it has no effect on the sealing performance after long using.
 2. Epoxy painting on the body, isolated to the medium, and avoid of corrosion.
 3. Triple sealing to protect against leakage in shaft, which ensures none leakage of valve.
 4. Setting up the inverted sealing actuator, which ensures in the condition of using  valve, it can change seal--packing, without dismantling valve.
 5. The high quality of seat rubber ensures its entailing performance and excellent re--elasticity.
 6. The excellent in corrosive performance..
     (1) Epoxy resin coating in the shell.
     (2) Adopting the interior six angle bolt in connecting bolt, rubber--sealing in top.
 7. Dependable hygienic.
     (1)Epoxy resin coating conforms to hygienic standard GB/T17219--1998.
     (2)Whole cover of disc conforms to the rubber of hygienic inspection.
