#CMT# #/CMT# A ball valve has a plastic housing (4) around a supporting structure (3) in which a ball valve (2) with a passage rotates between open and closed presentations. The supporting structure consists of two rings (10a, 10b) held together by a link fitting (11) and supporting the ball valve (2). The supporting structure completely separates the ball valve from the housing. #CMT#USE : #/CMT# Ball valve. #CMT#ADVANTAGE : #/CMT# The ball valve has a better seal than prior art. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of the ball valve. 2 : Ball valve 3 : supporting structure 4 : plastic housing 10a, 10b : rings 11 : link fitting. |
