The KOMOTO PR-1807A pressure reducing valves are the most advanced two-path control pilot type pressure regulators. Pilot type pressure regulators provide better accuracy and higher capacity compared to conventional direct type pressure regulators. And Two-path control type of pilot operated regulators offer quicker response time and more precise control ability than other types of pilot operated regulators.
The KOMOTO PR-1807A pressure reducing valves precisely control downstream pressure to a predetermined set-pressure. The superior performance of KOMOTO PR-1807A series is due to the amplifying effect of the pilot and the two-path control system. Changes in outlet pressure act quickly on the actuator diaphragm to provide fast response to system changes.
