The Modular Subminiature Relieving Regulator is configured for accurate pressure regulation with minimal consumption. It will only relieve pressure after the output has risen above the setpoint. This feature prevents excess consumption in the system. Pressure compensated design improves the performance of supply pressure variation and flow characteristics

The Unique Modular Dovetail design allows the regulator to be configured individually or assembled into a modular combination of pneumatic components.
