IMPCO Over Pressure Regulator Model Loper , LNG , Robust Design , On-Road / Off-Road Applications
Key Features
• Ideal for use in on-road and off-road applications
• Stainless steel components for continued
operation at cryogenic temperatures:
-- SS diaphragm (bellows) retains full
functionality at sub-zero levels
-- SS plunger body and all springs stay working
at sub-zero levels
• MAP (Manifold Absolute Pressure) reference
fitting is built into the design
• Retains steadier output than competitive models:
-- pressure balanced plunger design maintains
outlet pressure vs. flow (droop) performance
as inlet pressure varies
• Designed for operation with fuel temperatures
of -40°C to 120°C with excursions to -60°C
• Flexibility for a range of applications with
outlet pressure setting range from 3.8-9.0 barg
(55-130 psig) depending on model
• Robust design validated through rigorous testing
