The Modular Subminiature Non-Relieving Regulator is configured for accurate regulations of pressure without needing a pressure bleed. Setpoint creep and over-shoot are minimized by a combination of elastomeric seat and go high seat force. In an open system, Non-Relieving Regulator will operate without the risk of set point creep. In a closet system, Non- Relieving Regulator should only be used in combination with secondary relief.

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