Brief

The plunger valve structure characteristic is that when clockwise rotation handwheel does through the valve lever impetus plunger valve petal in the about packing ring to the under translation ,causes the plunger valve petal the nose conical surface hard seal ,its seal effect is especially good.

 

The plunger valve has the advantage of no leakage outside because of the features of hard-sealing and rapid open-close, forming new products of new structure and wide range of uses.
