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.
Control range: 0.005 to 45 BarG

1. PR-1807AEP — Very Low Pressure (Tank Blanketing Valve)
PR-1807AEP tank blanketing pressure regulators are used for accurate pressure control on very low pressure of gas blanketing systems, which is introducing an inert gas into a storage tank. Tank blanketing regulators reduce a high-pressure gas, such as Nitrogen, and maintain positive pressure in a tank which is slightly higher than atmospheric pressure. By maintaining the pressure, they reduce possibility of tank collapse while the liquid in the tank is being pumped out.
2. PR-1807ALP — Low Pressure, PR-1807AMP — Medium Pressure
PR-1807ALP/MP series pilot-operated, springloaded, diaphragm type regulators provide precise downstream pressure control at low and medium set pressures. The large pilot diaphragm area of PR -1807ALP provides more accurate control at lowpressure settings.
3. Piston Type PR-1807AHP — High Pressure
Introduction PR-1807AHP Series pilot-operated, spring-loaded, piston type regulators provide precise downstream pressure control at high set pressures.
4.PR-1807ALT — Low Pressure & High Temperature,
Introduction PR-1807ALT/HT Series pilot-operated, springloaded, piston type regulators are designed for high temperature services. The large pressure sensing area of PR-1807ALT provides more accurate control at low-pressure settings.
5.PR-1807AHT — High Pressure & High Temperature
Introduction PR-1807ALT/HT Series pilot-operated, springloaded, piston type regulators are designed for high temperature services. The large pressure sensing area of PR-1807ALT provides more accurate control at low-pressure settings.
