Structural advantages and characteristic

1.      The operation reduces effort: The medium pressure will produce the good action on the spheroid to transmit completely gives the lower bearing, the spheroid relative position migration, the both side valve seat seal stress will not be even, the operation moment of force will be low.

2.      Uses the spring pre-Canada load the movable metal valve seat structure, can be suitable, the high temperature, the high pressure as well as each medium pipeline.

3.      According to the request, may design can be suitable in contains medium and so on pellet, ground paste.

4.      Widely is suitable for medium pipeline and so on food, medicine, petroleum, chemical industry, natural gas, steel and iron, environmental protection, papermaking
