When choosing the port selection the input port is the starting point. The remaining ports are then selected counterclockwise. Part Number Guide FEATURES • Configurable Ports * Excellent Repeatability * Miniature Size • Non-Rising Stem with 20 Turns • Pressure Compensated Design • Very Low Bleed • Elastomeric Seat 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.
