Missiles & Space Pressure Regulators


Our family of piston-sensed pressure-reducing regulators are available in relieving and non-relieving configurations. For extremely low control pressure applications, bellows-sensed absolute pressure regulators are also offered. A wide range of available elastomer and PTFE soft goods ensure maximum compatibility with the process media.


Our pressure regulators are designed for reliable and dependable operation in propulsion pressurant systems used in reaction control systems (RCS) and attitude control systems (ACS). They are especially suitable when high vibration and large temperature extremes are present.
