The Marsh Bellofram Type 10 Air Pressure Regulator is designed to control output pressure with accuracy of 0.1% and high-repeatability, with very low sensitivity to changes in supply pressure, ambient temperature and flow.
The highly rugged design of the Type 10 includes unique features such as high start-up stability, which eliminates the need for regulated start pressure readjustment after long downtimes with automatic return to output setting at start-up; incorporation of a high-gain pneumatic servo amplifier for regulated pressure, ranging from dead end to 20 cubic meters per hour (12 SCFM), held constant over substantial flow changes.
Incorporation of an extra-large capacity integral relief valve, for exhaust flow when regulated pressure is reset to a lower value, with automatic high downstream relief under dead end conditions; and incorporation of a high-performance servo-operated control mechanism in the regulator, for added pressure stability.
The entire measuring element, including pilot valve, is fabricated from heat-treated stainless steel to eliminate hysteresis or permanent deformation under all working conditions.
An integral relief valve provides for exhaust flow whenever the regulated pressure is reset to a lower value.
In addition, the available Type 10 motorized configuration allows for easy integration into open- or closed-loop process control systems and programmable controllers.
