Project Description

Self-Acting Direct type Pressure regulator

The KOMOTO PR-1207A pressure reducing regulators precisely control downstream pressure to a predetermined set-pressure. Thanks to the innovative design, they provide quick response to sudden pressure changes.
The PR-1207A series regulators offer maximum capacity, quick response, and accurate pressure control. The optimized design for fast and easy maintenance will minimize the total cost of ownership.


  • Top-entry design for ease of maintenance
  • Variable actuator sizes for all pressure control ranges
  • Sufficient balanced diaphragm for increased sensitivity
  • Full port design for high capacity
  • Stable guiding piston design
  • Tight shut-off with soft seat at all pressure differentials
  • Excellent pressure control rangeability
  • Light weight and compact design
Control range: 0.005 to 45 BarG
Temperature Range : -25 ~ 200 ˚c
Size : 1/2” ~ 2”
