6 STRUCTURE AND FUNCTION

6.1 Structure

Theglobevalveconsistsofapneumaticallyactuatedpiston

actuator and a 2-way body.

Theactuatorismadefrompolyphenylenesulphide(PPS).The

proven,self-adjustingpackingglandguaranteesahighdegreeof

tightness.Thestainlesssteelvalvebodyaidsinowandfacili-

tateshighowrates.
