Optimal flow feature The flow road is similar to the pipe. It has no
popping parts and is suitable for the transportation of clotty and high
viscosity liquid. heat and cold insulation efficiency It use the total flow
jacket to have equal heat and cold insulation efficiency for all parts of valve
body Small volume, and weight The common jacket valve has big volume, and
weight. But the FCV jacket ball valve has the minimum volume, and weight among
all the jacket valves. Heat insulation jacket The outside of valve body is
welded by the jacket(carbon-steel shape). The permitted heat-insulation medium
is 1Mpa steam and cooling water.
