LQ Siries

LQ Series actuators are the new generation of our company and can be used for driving and controlling the butterfly valves,ball valves and plug valves (part-turn valves with 90° movement).With the functions of local control and remote control both.

  • They are widely applied to control on industry, waste and water treatmen, air conditioning, chemical engineering,food  industy and etc.
  • The enclosure protection is IP67,and the explosion proof class is d II CT6(LQ1,LQ2) and d II BT6(LQ3,LQ4,LQ4JS)

General

  • Integrated gas flow meter
  • Rate valve
  • Pressure gauge
  • Electrical full/empty alarm
  • Gas types: Cl2, SO2, CO2, NH3

Vacuum Regulators are designed to feed gas chlorine and with minor alterations also for other gases (SO2, CO2, NH3 ), working on the indirect vacuum principle. They are made of the best and most resistant materials. The springs are made of tantalum alloys, the inlet valve of technically pure silver, the casing of rubber and plastic mixture, the membranes and washers of quality materials like ECTFE foil, FPM/FKM, PTFE, PVDF, which all ensures faultless operation of these devices at high mechanical and temperature load.
