  • Modular design – The regulator is combined by actuator, trim, main valve and slam shut modules
  • All of the regulator can choose slam shut status signal electricity remotely transferred (Anti-explosion: EEx d IIC T6) except Type RTZ-40/0.4SE – 
  • Fast response, large flow rate – It’s suitable for the field that needs fast response, such as boiler; special design body can give more flow rate than same nominal diameter regulator
  • Full balance trim, good accuracy – Full balance trim can avoid influence of P1, increase the accuracy
  • Simple structure, convenient maintenance – All the modules can be pulled out, replaced or maintained in line except body
