6 STRUCTURE AND FUNCTION
6.1 Structure
Theglobevalveconsistsofapneumaticallyactuatedpistonactuator
anda2/2-wayglobevalvebody.
TheactuatorismadefromPA.Theself-adjustingpackinggland
guaranteesa highdegreeof tightness.The stainlesssteel valve
bodyfacilitateshighowvalues.
