CL94, CL44, CL51, CL52 Ball Valve

Brand: Worcester-Controls

Worcester Controls has the quality solution for tough applications involving chlorine, from the manufacture of the basic chemical to processes involving its use including pulp and paper bleaching and production of feedstocks. 

With many years experience in handling dry chlorine (less than 150 ppm water), Worcester offers two basic lines of valves; the Series CL44 and CL51/52 for general service and the Series CL94 for antifugitive emission containment and high-cycle applications. 

All valves feature leak-tight seats, adjustable stem seals, body cavity pressure relief and corrosion resistant materials. An emission monitoring port is standard with the CL94 design.
Features
  • A relief hole in the ball to bypass the upstream seat and ensure that expansion pressure in the ball and body cavity of a closed valve will relieve spontaneously toward the direction of high pressure
  • Stem seals that are externally adjustable to stop stem leakage
  • A bottom-entry stem to prevent accidental removal while valve is in service (CL44, CL51/52)
  • Internal stem retention (CL94)
  • Visual indication of valve position
  • Body, ball and stem materials proven compatible with chlorine
  • Special testing for seat tightness
  • Special cleaning
  • Special packaging
