Self-Acting Pilot type Back- Pressure regulator 2021-05-11T03:03:16+00:00

Project Description

Self-Acting Pilot type Back- Pressure regulator

The KOMOTO PR-1807R 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-1807R series regulators offer maximum capacity, quick response, and accurate pressure control. Amplifying effect of the pilot provides superior pressure control performance.

Features

  • Top-entry design for ease of maintenance
  • Full port design for high capacity
  • Stable guiding piston design
  • Tight shut-off with soft seat at all pressure differentials
  • Excellent pressure control rangeability
Control range: 0.005 to 20 BarG
Temperature Range : -25 ~ 200 ˚c
Size : 1/2” ~ 2”
