Project Description

Self-Acting Direct type Back- Pressure regulator

The KOMOTO PR-1207R back pressure regulators precisely control upstream pressure to a predetermined set-pressure. Thanks to the innovative design, they provide quick response to sudden pressure changes.
The PR-1207R 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.

Features

  • 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

Control range: 0.005 to 45 BarG
Temperature Range : -25 ~ 200 ˚c
