Pneumatic Control Valves for Steam (with Built In Separator & Trap)

PN-COS-16

Remotely controllable pneumatically actuated control valve

The PN-COS is a pneumatic control valve designed for remotely controlling steam pressure based on the structure of the TLV COS pressure reducing valve. As it includes integrated screens, separator, and steam trap, it also conditions steam quality, and is suitable for use in steam heating processes.

Benefits and Features

  • มีเครื่องแยกแบบไซโคลน สกรีน และกับดักไอน้ำ Free Float® ติดตั้งอยู่ในตัว
  • The rapid response pneumatic actuator precisely adjusts the valve position to ensure accurate pressure control.
  • Built-in cyclone separator, with condensate separation efficiency as high as 98%, and self modulating free float steam trap provide dry, high-quality steam supply.
  • Large surface area integral screens for pilot valve and main valve extend trouble-free service.
  • Combining with a controller and an electropneumatic transducer enables automatic PID operation
  • When combined with an air regulator it can be used as a pressure reducing valve to set secondary pressure remotely, and 2 point pressure switching is possible as well.
  • By adjusting the internal spring load, steam can continue to be supplied at the required lowest set pressure even with motive air cut off (emergency case).

Application Areas

  • เหมาะสำหรับการควบคุมอัตโนมัติของแรงดัน อุณหภูมิ และอัตราการไหลของน้ำ ไอน้ำ เป็นต้น
