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.

1.PR-1807REP — Very Low Pressure (External air supply is required)
PR-1807REP tank blanketing back pressure regulators are used for accurate pressure control on very low pressure of gas blanketing systems. Tank blanketing back pressure regulators maintain positive pressure in a tank which is slightly higher than atmospheric pressure by relieving the pressure of gas. By maintaining the pressure, they reduce possibility of tank explosion while the liquid in the tank is being filled in. Due to lack of actuating force, external instrument air supply is required.
PR-1807REP Set Pressure Range (BarG) : 0.005 ~ 0.05
Temperature Range • -25 ~ 80 ˚C
Diaphragm Material • Nitrile (NBR), Fluorocarbon (FKM)
Disk & Elastomer Seal Material • Nitrile (NBR), Fluorocarbon (FKM)
2.PR-1807RLP — Low Pressure, PR-1807RLT — Low Pressure & High Temp. (External air supply is required)
Introduction PR-1807RLP/LT series pilot-operated, springloaded, back pressure regulators provide precise upstream pressure control at low set pressures. PR1807RLT is designed for high temperature services. Due to lack of actuating force, external instrument air supply is required.
Temperature Range • -25 ~ 120 ˚C (PR-1807RLP) • -25 ~ 200 ˚C (PR-1807RLT)
PR-1807RLP Set Pressure Range (BarG) : 0.05 ~ 0.5
PR-1807RLT Set Pressure Range (BarG) : 0.05 ~ 0.5
Diaphragm/Piston Elastomer Material • Nitrile (NBR), Fluorocarbon (FKM)
Disk & Elastomer Seal Material • Nitrile (NBR), Fluorocarbon (FKM)
3.PR-1807RMP — Medium Pressure
PR-1807RHP — High Pressure
PR-1807RHT — High Pressure & High Temperature
Introduction PR-1807RMP/HP/HT back pressure regulators are unloading type pilot operated pressure regulating valves. PR-1807RP Series spring-loaded, diaphragm type pilot regulators provide precise upstream pressure control at medium range set pressures. PR-1807RHP Series spring-loaded, piston type pilot regulators are designed for high set pressure control services. PR-1807RHT Series pilot-operated, spring-loaded, piston type regulators are designed to provide upstream pressure control for high pressure & high temperature services.
Temperature Range • -25 ~ 120 ˚C • -25 ~ 200 ˚C (PR-1807RHT)
PR-1807RMP/HP/HT Set Pressure Range (BarG) : Max. 20
Piston Elastomer Seal Material • Nitrile (NBR), Fluorocarbon (FKM)
Disk & Elastomer Seal Material • Nitrile (NBR), Fluorocarbon (FKM)
